QUEDIUS Steph. 



Q. MORTUUS n. sp. (Plate I, Fig. 2.) Form elongate, parallel. Head 

 long, rather narrow, tapering behind the eyes which are large but not very 

 prominent. Antennae wanting. Prothorax wider than the head, but about 

 equal in length and breadth, apex narrower than the base which is rounded, 

 sides nearly regularly arcuate. Scutellum large, subtriangular. Elytra 

 conjointly but little wider than the prothorax, sinuately truncate at apices, 

 their combined width slightly exceeding their length. Abdomen nearly as 

 broad as the elytra, strongly margined, only the basal three segments re- 

 maining. Legs wanting. Length of fragment, 11.4.5 mm.; from front of 

 head to elytral apex, 7.60 mm.; of elytra, 2.80 mm. Width of prothorax,

Station number 14. Collected by S. A. Rohwer. The type and only speci- 

 men is in the American Museum of Natural History. 



This appeal's to be a Quedius of the explanaUis type and is of 

 similar size. The sculpture of the entire upper surface is very 

 fine and seems scarcely more than an alutaceous roughening of 

 the- integuments. In life, the insect probably reached a length of 

 about 15 mm.
