cells quite heavy. Third vein unforked and ending in the wing tip. 

 Second basal cell almost twice the length of first basal and about as 

 long as discal cell. Supernumerary cross-vein at base of first posterior 

 cell parallel with the short vein between the discal and second posterior 

 cells. All of the posterior cells are widely open. There are only two 

 veins emerging from the discal cell, the third branch, found in Eulon- 

 chus, Lasia and a few others having disappeared. 



Type. United States National Museum, No. 21074. One 

 specimen. Habitat. Chile. 



The genus Holops Phil, is probably the nearest to I 'Mains. 

 Holops inanis Phil, is yellow with yellow pile and has the 

 anterior margin and apex of the wings infuscated. Philippi 

 in his brief description mentioned that the small mouth open- 

 ing was triangular. He stated that he could see no proboscis 

 (as in H. cyancus), but thought it might possibly be strongly 

 retracted. No mention is made of the wing venation. The 

 head of Villains is like that of Holops and the antennae of like 

 structure and similarly placed. If the figure of H. cyaneus 

 given by Philippi can be relied on, the venation is quite dif- 

 ferent from Villains. Verrall in "British Diptera," Vol. Y, 

 p. 451, has a figure of the wing of Holops nigrapcx Big. which 

 is like that shown by Philippi in his "Aufzahlung der chileni- 

 schen Dipteren." In both of these figures the third vein is 

 forked and the veins posterior to this do not reach the wing 

 margin. Also the anal cell is closed some distance from the 

 margin and the discal cell has a third vein emerging from it, 

 missing in Villains. This is the only Cyrtid that I know of 

 which has short hairs on the wing membrane. 



Verrall in "British Diptera" stated that Megalybns gave a 

 clue to the venation of Oncodes and Acroccra and was a type 

 intermediate between Eulonchus and Astomclla. This genus 

 Villains has a venation very nearly approaching that of Mega- 

 lybns. We see in this form a modification of the more com- 

 plex venation of Lasia, Eulonchns and Pteropexus, and a 

 suggestion of the still more simplified venation of Oncodes. 



Material Desired (Coleoptera). 



Dr. W. D. Pierce, Bureau of Entomology, Washington, D. C., desires 

 to receive for study material in Gymnaetron, Linarla and Mianis.
