128 Wickham — New Fossil Coleoptera from Florissant. 



Scudder definitely stated that no sculpture whatever (except 

 certain raised lines) was shown in his examples. Further, the 

 entire facies of my specimen and particularly the small size of 

 the scutellum lead me to place it in Philydrus rather than in 

 Tropistemus. It is, of course, impracticable to carry the 

 identification into the groups (based upon palpal characters) 

 created by the dismemberment of the old genus Philydrus.

Podabrus Westw. 



P. ivheeleri n. sp. The type specimen, consisting of obverse 

 and reverse, shows One elytron entire and a part of the other, 

 the head, thorax and abdomen, one leg of each pair and both 

 antennae. Parts of the remaining legs are visible through the 

 overlying parts of the body. 



Head moderate, eyes small, apparently about as in Chauliog- 

 nathics pennsylvanicus. Antennae seemingly eleven- jointed, 

 moderately slender, the first joint larger, second apparently 

 about one half as long as the third, the fourth and following 

 considerably longer, all the joints, especially the proximal ones, 

 noticeably broader at apex. Prothorax apparently not greatly 

 differing in width from the head, broader than long, truncate 

 in front. Elytron subtruncate at tip, the disk finely costulate 

 (probably twice). Abdomen projecting beyond the elytra the 

 length of two visible segments; another may have been broken 

 off. Legs moderately stout for this family, the hind ones much 

 longer than the others. Tarsi all partially mutilated, so that 

 it is impracticable to describe individual joints, but the tarsus 

 of the middle leg seems to be of the type shown in the recent 

 Podabrus comes. The basal joint of this tarsus seems to have 

 been displaced. Length of specimen entire 17*25 mm , of ely- 

 tron ll mm , of antenna 7'50 mra , of hind femur 5 mm , of hind 

 tibia 5 mm .

A long study of this insect has resulted in maintaining it in 

 the position given it at first sight. The length of the abdomen 

 is probably due in part to maceration before the embedding 

 was completed. The antennae are essentially of a Podabroid 

 type, and I think the generic assignment is not far out of place. 

 As will be seen from the measurements, the size is considerably 

 above the average of the American species of Podabrus, but 

 this is largely due to what I consider the unnatural extension 

 of the abdomen. Nothing allied is known from the Florissant 

 shales. The fact that the specimen is preserved principally in
