FOSSIL COLEOPTERA 13 



Tritoma Fahr. 



T. SUBMERSA n. sp. (Plate III. Figs. 2. 3.) Fonn rather short for this 

 genus. Head large, broader than long, eyes not discernible in their entire 

 outline, but enough shows to indicate that they were of good size. An- 

 tennae mutilated but fragments of both remain, showing the basal joints 

 to have been slender and the club to be composed of three broad joints, 

 similar among themselves. Prothoracic width equal to double the median 

 length, hind angles a little rounded, anterior angles a little acute, sides 

 margined. The greatest width is slightly in front of the base, whence the 

 sides taper with slight arcuation to the apex. Scutellum small but distinct, 

 triangular. Elytra two and two-thirds times the length of the prothoracic 

 median line, conjointly noticeably broader than the prothorax, pointed at 

 the apex, exterior and sutural margins with a rather fine bead. Legs want- 

 ing. No distinct sculpture can be made out on the specimen, but the 

 elytra show faint signs of striae. Length. 2.50 mm. 



Station number 14. One specimen, collector not specified. The type is 

 in the Museum of the L'niversity of Colorado. 



Though rather small for this genus, the specimen seems to 



belong to the Erotylid* and appears more closely allied to 



Tritoma than to any other genus that I know. At any rate 

 there is no basis for generic separation. 



T. MATEKXA n. sp. (Plate II. Figs. 7. S.) Form rather short, resembling 

 that of the recent T. humeralis. Head comparatively a little larger than 

 that of the species cited, the sculpture, (except a few scattered fine punc- 

 tures), eye and articulations of the antennae effaced. Prothorax short, not 

 much arched in profile. Elytra cuneiform in side view, about three and 

 one-half times as long as the prothorax and a little more than twice as 

 long as high. Legs short, tibiae expanded towards the tips and flattened. 

 Length. 4.55 mm.; of elytron. 3.55 mm. 



Station number 14. One fine paired specimen, collected ty S. A. Kohwer. 

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



This beetle is strikingly like the recent T. humeralis in outline 

 and has the same leg construction as far as can be seen, except 

 that the hind tarsi are perhaps a trifle longer in proportion to 

 their tibiae in the fossil. The sculpture seems to have been finer, 

 the prothorax with very sparse punctuation, the el%i:ra with rows 

 of fine distant punctures. 



Phlqeonemites n. gen. 



This name is proposed for a fossil similar to the recent Plilaonemus 

 catenulatus in form, size and elytral sculpture, but differing in having the
