FOSSIL COLEOPTERA 23 



by one of the parties under the direction of Professor Cockerell. The type 

 is in the Museum of the University of Colorado. 



This is smaller than Atanius patescens and has a different 

 punctuation. The simple elytral stride, with the size, will separ- 

 ate it immediately from ApJiodius florissantensis and the impunc- 

 tate elytra will differentiate it from A. granarioides. I have 

 placed with the type, a second specimen collected at Station 17B 

 by Mrs. W. P. Cockerell. 



A. SHOSHOXis n. sp. (Plate YI, Fig. 3.) Form stout, nearly parallel 

 sided. Head short, clypeus broadly rounded anteriorly, without emargina- 

 tion. Prothorax about one and three-fifths times as broad as long, sides 

 subparallel from the base to beyond the middle, thence arcuate to the apex. 

 Front angles obtuse but well defined, hind angles obtuse and not prominent. 

 Scutellum moderate. Elytra, separately, nearly twice as long as wide, 

 with strong, fine, sharp strife, which seem to be impunctate. Legs not in very 

 good preservation, the armature of the front tibiae being indefinite and 

 all the spurs gone except those of the hind leg which seem to be slender 

 and equal. The hind tibia and tarsus are fairly well shown and are quite 

 slender. Length, 2.95 mm. 



Station number 17. Collector not specified, but the insect was secured 

 by one of the parties under direction of Professor Cockerell. The type is 

 in the Museum of the University of Colorado. 



I place this insect in Aphodius and feel sure that it belongs in 

 that genus in its broad sense at any rate. The clypeus is of a 

 type uncommon in Aphodius proper, but resembles that of some 

 species oiJEgidlia. The legs, however, seem too slender to permit 

 of association with this latter genus. I have not attempted to 

 describe the sculpture of the head and prothorax. since the speci- 

 men is too thoroughly carbonized to permit this character to be 

 made out. 



A. LAMINICOLA Wicllj. Station number 14. A good specimen was col- 

 lected here by Mrs. W. P. Cockerell. It offers no characters additional to 

 those given elsewhere. 



Serica Mac Leay. 



S. AXTEDiLrviAXA n. sp. (Plate VI. Fig. 6.) Form, viewed in profile, 

 only moderately stout for this genus. Head fairly large. Prothorax short, 

 about one and a half times as high as long, no definite sculpture visible on 

 either of these parts. Elytra nearly smooth but with some evidence of the 

 presence of shallow striae. Abdomen finely alutaceous. Legs stout, fore
