IO4 MEMOIRS ON THE COLEOPTERA 



concavo-explanate and more coarsely, closely punctate laterally, 

 the edge narrowly rugose transversely, slightly thick and not g^t all 

 serrulate; base truncate medially, broadly sinuate laterally; elytra 

 fully one-half longer than wide, oval, with arcuate sides, widest 

 slightly behind the middle, the humeri very obtuse and blunt but 

 evident; first discal costa broad but feeble, scarcely being more than 

 a tumid ridge, the second very broad but more or less distinct, usually 

 with fine distinct crest, the dorsal space across the suture between the 

 second ridges convex to almost flat, outside the second ridge steeply 

 declivous, the acute margin ending at some distance from the apex; 

 surface with large but feeble ruga?, almost even laterally, without 

 evident granules or hairs; abdomen sparsely, not very coarsely, 

 asperulately punctate, less sparsely so medially. Length 17.0-18.0 

 mm.; width 8.7-9.6 mm. Texas (Alpine), H. F. Wickham. 



sycophanta n. sp. 



Under the species identified above as sordida, because of its 

 small prothorax, I have included a number of subsidiary forms, 

 represented for the most part by single specimens, and have simply 

 quoted from the original description of the author for its character- 

 ization, being compelled for the time being to merely indicate its 

 probably correct place in the series. The forms here described as 

 species are all valid with, I think, scarcely any doubt, and it is 

 probable that a number placed as subspecies will also prove rather 

 to be species than of subordinate weight, this being especially the 

 case with obesa, furtiva, fulvisetis and imperfecta. The conspicuous 

 modification of the last ventral segment in the female of procrustes 

 is such an isolated character in the genus, that I have sometimes 

 thought it might be accidental; its bilateral symmetry would how- 

 ever seem to indicate that it is normal to the species, which is ob- 

 viously distinct from its fellows in many other characters as well. 

 It is impossible to prove, because of limited material, whether 

 the peculiar free ends of the costae in fulvisetis and imperfecta, there 

 being not the faintest indication of the usual posterior union, is a 

 constant character or not; if constant these forms would be species 

 without a doubt, but meanwhile I have given the character no 

 weight at all, the subspecies being separated wholly on general 

 features of form and sculpture. 



The Mexican rugosissima and interrupta, of Champion, also belong 

 to Glyptasida, the latter probably being one of the subspecies of 

 agra Lee. Of the former I have a large series from Durango.* 



* Rugosissima is a species evidently distinct from sordida, or any other of the American 

 species, being smaller, shorter, more convex, duller, more rugose and invariably coated
