Texas. The punctures of the head, thorax, and elytra are 

 furnished with short hajrs ; those of the abdomen with longer 

 ones ; the antennae are one-fourth longer than the head, and con- 

 siderably thickened externally, the outer joints being fully twice 

 as wide as long. The form of body is still more slender than in 

 Ocypus ater. 



STAPHIXIffUS LINN. 



122. S. conies. Fusco-seneus, fulvo-pubescens, capite thoraceque den- 

 sissime punctatis, hoc latitudine paulo longiore linea angusta dorsali 

 Isevi, elytris dense subtiliter punctatis, fusco subvariegatis, abdomine 

 supra bifariam nigro-maculato, apice piceo-rufo ; subtus nigro-piceus, 

 abdomine lateribus sericeo-maculatis, pedibus rufo-testaceis, femoribus

Southern States ; Dr. Zimmermann. Resembles in appearance 

 S. maculosus, but is much smaller, with the medial smooth stripe 

 of the thorax very distinct, and the legs brownish-yellow. The 

 scutellum is covered with a dense patch of black hair. 



It is possible that it may be a light-colored variety of S. mys- 

 ticus Er., a species unknown to me. 



123. S. carbonatus. Niger nitidus, nigro-pubescens, capite tho- 

 raceque confertim punctatis, illo linea Isevi antice obsoieta, hoc latitu- 

 dine paulo longiore vitta dorsali Isevi notato, elytris dense punctulatis, 

 abdomine immaculate, pedibus nigro-fuscis. Long. -50. 



Western States. Quite distinct by the above characters from 

 any other species known to me. The sides of the thorax are 

 parallel, or perhaps converge a little from the anterior angles. 



124. S. toadipes. 2Eneo-niger, nigro-pubescens, capite thoraceque 

 confertissime punctatis, linea angusta dorsali Isevi ornatis, hoc latitudine 

 vix longiore, elytris dense punctulatis, abdomine segmentis 2 6 macula 

 basali flavo-pubescente ornatis, antennis rufo-piceis, pedibus ferrugineis. 

 Long. -50 -56.

 sota.
