DESCRIPTIONS OF NEW SPECIES. 141 



CTENIOPUS SOLIER. 



430. C. murrayi. Elongatus fuscus nitidus pubescens, capite tho- 

 raceque subtiliter punctulatis, hoc latitudine sesqui br^viore, a basi 

 antrorsum angustato, lateribus antice valde rotundatis postice sub- 

 sinuatis, ad medium vage impressis, basi subsinuata, tenuiter margi- 

 nata, angulis posticis subacutis vix rotundatis ,*>elytris thorace latioribus, 

 punctatis, striis haud impressis, e punctis vix majoribus approximatis 

 digestis. Long. -40. 



One specimen (female) given me by Mr. Andrew Murray, 

 probably from Florida. I am not entirely satisfied with the 

 reference of the species to the present genus. The tip of the man- 

 dibles is simple, slightly rounded, and not emarginate ; the last 

 joint of the maxillary palpi is elongate triangular, with the apical 

 and basal sides equal, the .outer lobe of the maxillae is elongate 

 with parallel sides ; the antennae are slender, about one-half the 

 length of the body, with the 3d joint a little shorter than the 4th. 

 The lateral margin of the prothorax reaches the tip ; the anterior 

 coxa3 are separated by the prosternum. The tarsi are simple, 

 not longer than the tibise, and the ungues have from 6-8 teeth ; 

 the posterior portion of the hind coxaa is slightly convex, and 

 does not terminate in a sharp edge. The 6th ventral segment is 

 slightly visible, and the 5th is marked with a transverse oval ex- 

 cavation near the tip. The epipleurse extend nearly to the tip. 



The family Cistclidss seems to need a thorough revision, in 

 order that by comparing the species from different countries the 

 limits of the genera may be properly denned, and their systematic 

 relations recognized. 



8TATIRA LATR. 



431. S. sulm itida. Picea vel nigro-pioea, capite thoraceque alnta-ceo- 

 rugosis, fere -opacis, hoc latitudine longiore lateribus late rotundatis, 

 apice truncate, angulis rotundatis, basi marginata, angulis posticis ex- 

 trorsum prominulis ; elytris thorace fere duplo latioribus, subtiliter 

 reticulatis subnitidis, striis punctulatis, interstitiis alternis punctis 

 paucis piliferis impressis. Long. -30 -47. 



Two specimens, collected by Mr. John Xantus, at Cape San 

 Lucas, Lower California. The last joint of the antennae is de- 

 cidedly longer than the two preceding in the smaller specimen, 

 and about equal to them in the larger one. The difference is not 

 sufficient to be regarded as sexual, if I may judge from the other
