FOSSIL COLEOPTERA 35 



circular punctures, not very regularly spaced but those of each series are 

 ordinarily separated by about their ovra diameters or less. Legs long, 

 hairy, femora not toothed, the appearance of a denticle on the front femur 

 being due to an imperfection of the margin. Tarsi short, the front joint 

 of the hind ones nearly as long as the remaining three. Abdomen and 

 thoracic sternites nearly smooth, pygidium exposed. Length from front of 

 head to abdominal apex, 7.00 mm.; of beak, 6.75 mm. 



Station number not specified. One specimen, collected by Geo. X. Roh- 

 wer. The type is in the Museum of the University of Colorado. 



This insect forms part of a sending received directly from Pro- 

 fessor Cockerell. It is undoubtedly a Docirhynchus and is near- 

 est D. culex, but is about two-thirds as long again and has a 

 rostrum of relatively greater length. It is like nothing else from 

 the Florissant shales and is interesting as adding another species 

 to the already large number of Rhyuehitidie from that region. 



Pachybaris Lee. 



P. RUDls n. sp. (Plate II, Fig. 17.) Preserved as a reverse, in profile. 

 Form short, stout, the dorsal outline more convex than in the recent P. 

 porosus. Head with fine granules irregularly disposed above the eye but on 

 the beak arranged in longitudinal series with rather distinct intervening 

 carinse. Eye distorted, squarish, in life probably nearly round. Antennae 

 wanting. Prothorax short, closely covered with rather large granules, 

 some of which show a faint median indentation which may be the mark 

 of a hair. Elytra displaying only a portion of the lateral disk, showing 

 four sharply elevated narrow carina?, broken by shallow notches into a series 

 of elevations which are much longer than wide, the spaces between the 

 carinae not less than three times as -ivide as the ridges, their bottoms broken 

 by rather distant transverse impressions into oblong spaces, but hair marks 

 are not certainly visible. Underside of nieso and metathorax granulate 

 similarly to that of the prothorax, of abdomen much more sparsely so. 

 Abdominal ventral surface ascending, the first and second segments long, 

 the dividing suture indistinct, third and fourth short, subequal. fifth about 

 equal to the two preceding, the sutures of these last three segments sharp 

 and distinct. Legs wanting or obscured. Length, excluding beak, 3.45 

 mm. Height at middle, 2.20 mm.; the other body proportions may be ap 

 proximated by reference to the figure. 



Collected at Florissant by a party in charge of Professor Cockerell, 

 in March, 1911. The type is in the Museum of the University of Colorado. 



Remembering that the specimen is a reverse, we should have in 

 life an insect of the form and size of P. porosus, with irregularly 

 punctured head, the beak longitudinally striatopunctate in like 

 manner, the prothorax. with the sides of the meso and meta-
