places. Length, to abdominal apex, 7.75 mm. If the head were in 

 the presumed natural position, instead of being deflexed, the length 

 would be about 1 mm. greater. 



Described from one specimen, with counterpart. 



Type No. 2,697, 2,698 M. C. Z. Florissant, Col. (No. 8,312 

 and 8,317 S. H. Scudder Coll.). No. 2,699 M. C. Z. (No. 1,526 S. H. 

 Scudder Coll.) is probably a poorly preserved example of the same 

 species. 



While this insect is a little smaller than the recent T. fuha of New 

 Mexico, it resembles it quite closely in form and has similar vestiture. 

 The relative size of the head is about the same in the two species and 

 except that the joints are shorter in the fossil the antennae are not 

 unlike. No true generic characters are to be made out, but the general 

 resemblance to Tetraonyx is very well marked. 



EPICAUTA SUBNEGLECTA, sp. nov. 

 Plate 16, fig. 6. 



Preserved in side view. Form quite stout. Head very poorly out- 

 lined and not showing the shape of the eyes but it is only of moderate 

 size and without definite sculpture though appearing subrugose under 

 high power. Antennae showing only a few of the proximal joints 

 which are strongly hairy. Prothorax nearly smooth but with many 

 rather long hairs. Elytra similarly clothed and not visibly punctate. 

 Legs rather slender. Length, to abdominal apex, 6.50 mm. ; of elytron, 

 4.30 mm. 



Described from one specimen with counterpart. 



Type. No. 2,700, 2,701 M. C. Z. Florissant, Col. (No. 478 and 

 4,278 S.H. Scudder Coll.). 



This is rather small for an Epicauta. It has the shaggy look of the 

 recent North American E. puncticollis. The generic reference may 

 have to be changed if more perfect material becomes available. 



CANTHARIS LITHOPHILUS, sp. nov. 

 Plate 16, fig. 7. 



Form slender. Head small for the genus roughly suborbicular. 

 Eyes not well defined. Antennae short and stout as in several recent
