A slightly smaller and more robust species than the preceding with 

 the elytral costal much less elevated and the punctures of the intervals 

 even more indistinct. 



Two specimens, southwestern Texas. 



The genus Grlaresis was indicated, and the characters given rather 

 summarily by Erichson, but to Westwood we owe a full exposition of 

 its details. Regarding its systematic position there is some doubt as 

 Westwood places it among the Orphnides, while Erichson and Lacor- 

 daire consider it a Trogide. The material at my disposal does not admit 

 of dissection, and I can only accept the views of the last named authors. 



Grlaresis might be compared in form to some of our Aegiali^e. From 

 Trox it differs in having the first joint of the antennae cupuliform and 

 the abdomen small, membranous and retracted under the posterior coxae. 



The only species at present described is G. Frivaldskyi Ww. from 

 Hungary and it is very remarkable to find now two species in our coun- 

 try and in such a very remote region. 



As there are now three species known the following sketch gives in 

 brief their distinctive characters. 



G. Frivaldskyi Westw. Head with very distinct transverse impres- 

 sion from the base of each antennae, median line of front distinctly 

 impressed. Thorax — a deep post-apical impression^ deeper near the angles, 

 median line very deeply sulcate, an oblique fovea each side of median 

 line in front of middle and another posterior to the first but more distant 

 from the median line, a depression near the middle of the side margin ; 

 sides of thorax, straight, convergent to the front, the margin crenulate ; 

 surface with small granulations. Elytral costae well marked, intervals 

 with distinct fovese. 



G. mendica Horn. Head obsoletely foveate at the base of the an- 

 tennae, no median groove. Thorax — post-apical line distinct not deeper 

 externally, median line moderately deeply excavate, an oval fovea near 

 the median line slightly in front of middle, another near the middle of 

 side margin. Elytral costae moderately elevated, the foveae of the inter- 

 vals indistinct. 



G. inducta Horn. Head as in mendica. Post-apical line of thorax 

 feeble, median line feebly channeled a feeble fovea near the side margin. 

 Elyti'al costae feeble, the fovese of the intervals scarcely distinct.
