base, with strong bristles on the sides and at the tip ; male genitalia a little prominent, 

 lyegs short and stout ; middle tibiae with a single spur ; claws of the male very 

 short, the last tarsal joint a little dilated. 



Wings long, with a small costal bristle ; auxiliary vein indistinct at the end ; 

 first vein short ; 2nd straight ; 3rd bristly throughout its length, curved beneath near 

 the tip ; small cross-vein after the middle of the discal cell ; posterior cross-vein per- 

 pendicular ; anal cell drawn out into a broad point, as long as the 2nd basal cell. 

 Pattern consisting of a broad yellow band along the fore border and of some streaks in 

 the posterior half. 



Type : the following species. 



This genus is an aberrant one in the absence of the or. , but it shows all the other 

 characters of a true Trypaneid. It is very probable that some Oriental species, placed 

 by the authors in the Ortalids, belong here, as some Xiria, etc. The Neotropic genus 

 Xanthacrona, Wulp, has a very similar shape of the head ; but this genus is a true 

 Ortalid, as stated by Prof. Hendel in his recent paper on the '' Pterocallina." More 

 affinity is perhaps presented with the Oriental genus Lagarosia, which however is 

 unknown to me. The genus Chaetellipsis shows a remarkable likeness with Ceratitis 

 s. Str., and notwithstanding the yellow bristles of the occipital row is a true Cera- 

 titinine.

 pubescence, which on the pleura is longer and darker ; all the bristles black, only the 

 median pair of scp. being yellow. The post-alar calli and a transverse band in front 

 of the scutellum black ; the humeri and a band on the upper portion of the mesopleura
