emarginate; surface with a broad, obsolete depression along anterior 
margin, and with the sides broadly depressed, the depression becom- 
ing obliquely broader posteriorly, and broadly concave along the base, 
causing the median anterior part of disk to be strongly convex, 
sparsely, irregularly punctate, the punctures very shallow, obsolete, 
and from the center of which arises a very short, inconspicuous, cine- 
reous hair; intervals finely and densely reticulate. Scutellum tri- 
angular, obsoletely reticulate, feebly rounded in front. Klytra rather 
strongly convex, slightly narrower than pronotum at base; humeral 
angles rather obtusely angulated; sides rather strongly sinuate behind 
the humeri, as wide at the middle as at the humeral angles, strongly, 
obliquely attentuate from the middle to the apex, which is conjointly, 
broadly rounded, and obsoletely serrate; humeri well developed; each 
elytron with a deep, rather broad basal depression, and without lat- 
eral carina; surface with rows of large, shallow punctures, which are 
less impressed toward the apex, the rows somewhat confused near the 
base, and each puncture bearing a very in@onspicuous, cinereous hair; 
intervals coarsely rugose anteriorly, becoming finely and densely 
granulate at the apex. Abdomen beneath strongly convex, sparsely 
and obsoletely punctate, the punctures shallow, oblong, and open 
on the one side, very sparsely clothed with obsolete, cinereons hairs; 
intervals finely and densely reticulate; last segment broadly rounded 
at apex, with the apical groove following the outline of the margin. 
Metasternum with the surface similar to that of the abdomen. Pro- 
sternum finely and densely rugose. 
Length, 2.75 mm.; width, 1. mm. 
Type locality Panama City, Panama. 
Type and paratype.—Cat. No. 25122, U.S.N.M. 
Described from two male specimens collected by A. H. Jennings 
April 23, 1911. This species resembles 7. communis Waterhouse 
very closely, but can be distinguished from that species by the pro- 
notum being widest at the base and the elytra not quite as wide as 
the pronotum. 
Genus CALLIMICRA Deyrolle. 
Callimicra H. Deyrouuez, Ann. Soc. Ent. Belg., vol. 8, 1864, p. 219.
