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, Lasta 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 Villalus. 
Holops inants 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. cyaneus), but thought it might possibly be strongly 
retracted. No mention is made of the wing venation. The 
head of Villalus 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 Villalus. Verrall in “British Diptera,” Vol. V, 
p. 451, has a figure of the wing of Holops nigrapex 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 Villalus. This is the only Cyrtid that I know of 
which has short hairs on the wing membrane. 
Verrall in “British Diptera” stated that Megalybus gave a 
clue to the venation of Oncodes and Acrocera and was a type 
intermediate between Eulonchus and Astomella. This genus 
Villalus has a venation very nearly approaching that of Mega- 
lybus. We see in this form a modification of the more com- 
plex venation of Lasia, Eulonchus 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, Linaria and Miarus.
