BEROSUS LEACH. 



75. B. pllgnax. Elongato-ovatus, convexus, supra testaceus nitidus, 

 capite punctulato laete aeneo, thorace punctate, medio infuscato, elytris 

 striis confertiin punctatis, interstitiis vix convexis fortiter punctatis, 

 maculis pluribus nigris ornatis, apice singulatim emarginatis et bis- 

 pinosis, spina exteriore lougiore. Long. -24. 



Louisiana; Mr. Ulke. The black spots of the elytra are 

 arranged thus : a humeral one ; then two on each elytron forming 

 with those of the other side a transverse band convex behind ; 

 then an undulated oblique band formed of small spots, and 

 finally two small spots, one on the second and the other on the 

 fourth interstice, the inner one being the more posterior ; the 

 sutural spine is very short, the outer one long. The body be- 

 neath is black ; the palpi, antennae, and legs are pale testaceous. 



CYIXIDIIJM EK. 



76. C. atruin. Hemisphaericum, nigrum nitidum, thorace lateribus 

 piceis, elytris parce punctulatis, stria suturali profunda, versus basin 

 obliterata, antennis pedibusque piceis. Long. -09. 



York. Resembles in color and sculpture C. nigrellum, 

 from the Colorado Yalley of California, but is larger ; the elytra 

 are, perhaps, more strongly punctulate. 



PHILHYDRIJS SOL. 



77. P. simplex. Longior, ellipticus convexus, piceo-testaceus niti- 

 dus, capite thoraceque punctulatis, elytris fusco-lineatis minus subtiliter 

 punctulatis, stria suturali profunda antice obliterata, prosterno haud 

 carinato, mesostemo vix carinato ; subtus nigro-piceus, pedibus rufo- 

 pioeis. Long. !!. 



Louisiana ; Mr. Ulke. Differs from all our other species 

 having the mesosternum feebly carinate by the small size. In 

 shape it resembles P. nebulosus, but is very much smaller. 



78. P. censors. Longiusculus, ellipticus convexus, piceo-niger niti- 

 dus, subtiliter dense punctatus, thorace latitudine duphj breviore, lateri- 

 bus obliquis paulo rotundatis, angulis omnibus rotundatis, elytris 

 punctis majoribus serie quadruplici minus distincte digestis, stria sutu- 

 rali paulo ante medium obliterata ; antennis rufo-piceis. Long. '29--3U.
