These experiments with Locusta migratoria show that temperature conditions during breeding have a great influence on the normal development and general health of this insect. There is a certain limit of favourable temperature, below which the development of the genital products in the imagines ceases, and the insects easily succumb to bacterial diseases.

Megastes grandalis was first reported from Brazil ; there have been no other records until 1919, when it was reported from Trinidad as a serious pest during certain seasons of the year to the roots and tubers of the sweet potato. At present this is the only known food-plant.

The eggs are laid two or three together in the axils of the leaf-petioles or on the underside of the leaf. The laxva at first feeds near the place where it hatches, then travels to the base of the stem and bores its way in, eating out tunnels through the roots and tubers, leaving the cortex untouched. It pupates in a silken cocoon near the surface. The moths live only a few days during which oviposition takes place. Descriptions of the immature stages are given. The writer obtained a Trichogramma egg parasite and Tachinid larval parasites.

This work was undertaken at the Imperial College of Tropical Agriculture, Trinidad, West Indies.

The Imperial Bureau of Entomology kindly identified the parasites.

Specimens of the interesting new species described herewith came into the hands of both authors of this paper at about the same time from the same source, and were determined by each as new to science. Each being in ignorance of the fact that the other had received specimens, both proceeded to describe it. Before either description was published, however, the duplication was discovered through correspondence, and the description has been made the subject of this joint paper. The type and allotype specimens are in the United States National Museum, but paratypes are in the British Museum as stated below.

Ectropis deodarae, sp. n.

♂ 38–40 mm. Face rough-scaled. Palpus rather short, rough-scaled beneath. Tongue rather short and slender. Antenna with ciliation about 1, not or scarcely fasciculate. Thorax apparently not crested. Pectus densely hairy. Femora moderately hairy. Hind tibiae not dilated. Abdomen slender, not long. Head and body brown-grey, slightly paler beneath than above ; fore leg banded.

Some months ago I received from Dr. Guy A. K. Marshall, Director of the Imperial Bureau of Entomology, London, a collection of termites from Ceylon which he kindly entrusted to me for the purpose of identification. The termites were collected by the Government Entomologist of Ceylon, Mr. T. C. Hutson, in different parts of the island, in tea plantations. If this is the case, the termites were presumably not collected on the plains but at some height above the sea-level, where tea preferably is cultivated. There are, however, no detailed records of the height of the localities.

Theresia (Procris) ampelophaga, Bayle, a moth of the family Anthroceridae (Zygaenidae) is one of the most important pests of the vine in various countries, but the existing accounts of its bionomics are very contradictory and not free from inaccuracies.

From June 1925 to December 1925 a number of Phlebotomus, considered at first to be Phlebotomus minutus, Rondani (1843), were collected in Jericho. As Austen (1921) had recorded P. minutus var. africanus, Newstead (1912), from the Jaffa district and Buxton (1924) had recorded P. minutus only from Haifa and Jerusalem and did not find among his material any specimens with the palpal formula of P. minutus var. africanus, we commenced a systematic examination of our material with particular reference to palpal characters in order to determine whether any varieties of P. minutus occur in Jericho.
