During the course of revisional studies of the tribe Larvaevorini, a number of undescribed species were received from outside sources. Rather than delay the return of specimens, and on the chance that the final revision will not be published for some time, the descriptions of these new forms are given below.

Juriniopsis aurifrons new species

Until the present only one species of Juriniopsis, adusta Wulp. (floridensis Tns.) has been recognized from the United States. The new species, which ranges in Arizona, New Mexico and Utah differs from adusta Wulp. in the following characters: female front tarsus slender (widened and flattened in adusta); male vertex 0.35 head width (0.27 head width in adusta); parafrontals subshining yellowish with yellowish or brownish-yellow pollen (subshining bluish-grey with greyish or yellowish-grey pollen in adusta), and in the structure of the genitalia.
