Bruchus florissantensis Wickham.

 S. H. Scudder Coll.). 



TENEBRIONIDAE. 

 Protoplatycera, gen. nov. 



Aspect tenebrionoid. Integuments heavy. Form probably mod- 

 erately slender, the prothorax narrower than the elytra. Sculpture 

 light. Head rather small, eyes nearly circular, separated on the vertex 

 by about the width of one. Antenna with the two (or possibly three, 

 since the second may be small and inconspicuous) basal joints slender, 

 the remainder broad and flat, proportioned as shown in the figure. 



Type. — P. laticornis, sp. nov. 



Protoplatycera laticornis, sp. nov. 

 Plate 14, fig. 3-4. 



Moderately elongate, as preserved, in life probably less so. Head 

 narrow, longer than wide. Eyes small, suborbicular. Antennae, 

 if extended backward, reaching slightly beyond the elytral bases. 

 Prothorax apparently only about as wide as the head, with subparallel 

 sides, but not in very good condition. Elytra rather short, a little 

 more than two and one half times as long as wide, apices bluntly 

 rounded. Legs poorly preserved but evidently moderately stout. 

 Length, in position on the stone, from front of head to abdominal apex, 

 7.10 mm.; of elytron, 3.80 mm. 



Described from one specimen. 



Type.— No. 2,678 M. C. Z. Florissant, Col. (No. 13,070 S. H.

A remarkable insect which I have placed for the present in the 

 Tenebrionidae, without being able to suggest any tribal affinities. I
