530 SUPPLEMENT. 
CONIBIUS (p. 133). 
Conibius brunnipes (p. 133). 
To the localities given, add:—Mexico, Chihuahua city, Villa Lerdo in Durango 
(Hoge), Chilpancingo (H. H. Smith), Atlixco (F. D. G.). 
2. Conibius troglodytes. 
Moderately elongate, broad, convex, very robust, glabrous, subopaque, black, the sides of the head and of the 
prothorax, the oral organs, antennee, and legs obscure rufous. Head exceedingly broad, closely, minutely 
punctate, the eyes small; prothorax strongly transverse, bisinuate at the base and apex, widest slightly 
before the middle, the disc longitudinally convex, the sides broadly, horizontally expanded, a little rounded 
anteriorly, and slightly converging behind, the anterior angles broadly rounded, the hind angles very 
obtuse, the disc densely, very minutely punctate, the lateral portions more distinctly punctured ; elytra 
rather more than twice as long as, and not wider than, the prothorax, subparallel, narrowing a little 
anteriorly, finely punctate-striate, the interstices feebly convex and closely, minutely punctate, the humeri 
rounded; beneath shining, sparsely, finely punctate; prosternum slightly produced, concave at tip; 
intercoxal process of the abdomen comparatively narrow, rounded at the apex; legs exceedingly stout. 
é. Ventral surface broadly longitudinally depressed in the middle towards the base, the fifth segment also 
depressed in the centre; the anterior tibie merely a little widened. 
Length 7, breadth 3} millim. (<¢.) 
Hab. Mexico, Cacahuamilpa in Guerrero (Flohr). 
This insect, Mr. Flohr informs me, was found under a stone, with ants, at the 
entrance of the cave of Cacahuamilpa. C. troglodytes is allied to C. gagates (Horn), 
from Arizona, from which it differs in the broadly expanded lateral margins of the 
thorax, and in the finely punctate-striate elytra, the interstices of the latter being 
slightly convex. 
ULUS (p. 133). 
3. Ulus comatus. 
Elongate-elliptical, convex, piceous or pitchy-brown, shining, thickly clothed with long, coarse, appressed, 
whitish or yellowish-cinereous hairs, the prothorax coarsely fimbriate at the sides and base, the elytra 
with very long projecting marginal ciliw. Head closely, rather coarsely punctate; prothorax strongly 
transverse, bisinuate at the base and deeply emarginate at the apex, the sides rapidly converging from 
the base, a little rounded anteriorly, the surface rather sparsely, coarsely punctate, the punctures somewhat 
closer at the sides; elytra rather deeply punctate-striate, the punctures moderately coarse and approxi- 
mate, the interstices thickly punctured, almost flat; beneath coarsely punctate; anterior tibia broadly 
produced at their outer apical angle. 
¢. Anterior tarsi very feebly dilated ; fifth ventral segment slightly depressed in the middle at the apex. 
Length 53-64 millim. (¢ @.) 
Hab. Mexico, Vera Cruz (Flohr). 
Four examples, two of each sex, the females considerably larger than the males. 
Allied to U. obliquus (Lec.), U. fimbriatus, Casey, and U. hirsutus, Ch., but differing 
from these species in the much longer pubescence of the upper surface; the thorax is 
more sparsely and more irregularly punctured than in U. obliguus and U. hirsutus. 
Found on the sand-hills on the coast, according to Mr. Flohr.
