short a little before the end of the first vein and then crosses the wing 

 in a straight line, ending behind the end of the sixth vein; inside of 

 the hyaline space enclosed by this arch, there is an angular figure of 

 a paler brown, in the shape of a greek lambda, the tip of which is

connected with the arch, the somewhat curved proximal branch covers 

 the posterior crossvein and ends in the posterior margin, behind the 

 fifth vein; the straight distal branch ends in the second posterior cell, 

 behind the fourth vein. — A single male. 



NB. There is a distinct costal bristle; the anal cell is drawn out 

 in a short, but well defined, thumblike point, the crossvein separating 

 that cell fi'om third posterior forming a deep, retreating angle. The 

 form of the anal cell, as well as the general shape of the wing and 

 the venation are those of Ceratitis; but the bristles of the third vein 

 are very small, and the fronto- orbital bristles are not expanded into 

 lamels at the tip. For this reason I leave this species in the genus 

 Trypeta, in the wider sense. 



Trypeta Alkestis n. sp. $. Yellowish-ferruginous; thorax 

 with four dark brown stripes; the outer ones are interrupted at the 

 suture and connected posteriorly, in front of the scutellum, with the 

 corresponding inner stripe; a narrow black or brown longitudinal line 

 in the middle of the mesonotum, between the two pairs of stripes; on 

 each side, above and in front of the root of the wings, there are ves- 

 tiges of short brown lines. Metanotum black on each side with a 

 narrow yellowish-red space in the middle. Abdomen in the middle of 

 each of the segments 1 — 3 with an arcuated black crossband, which 

 reaches the lateral margins on both sides and is attenuated in the 

 middle; the last segment is black, with but little reddish in the middle. 

 Legs yellowish -ferruginous; halteres yellowish. Wings brown, with a 

 design composed of yellow spots : on the anterior margin a square spot 

 between two triangular ones; on the posterior margin a double spot
