20 erottldxe. 



A species easily to be separated from D. Iwvicollis, which it rather nearly resembles 

 in sculpture, by its somewhat stouter and shorter form, blue-black colour, and the 

 coarse sculpture of the prosternum. The body beneath is black ; and the very obsolete 

 denticulation of the tips of the elytra is noticeable, showing as it does how this 

 character fails to be of much generic importance. 



Three specimens in Salle's collection. 



11. Dasydactylus zunilensis. (Tab. I. figg. 8, 8«, <j ; 9, 2 .) 



Nigro-subameus, nitidulus, corpore subtus pedibusque saturatius piceis, antennis tarsisque nigrescentibus ; 

 capite protboraceque parcius subtiliter punctatis; elytris leviter punctato-striatis, apicibus rotundatis et 

 denticulatis ; prosterno ad apicem exciso, sub-bimucronato. Long. 13 millim. 6 2 . 



Mas prothorace latiore et convexiore; pedibus anticis longioribus, femoribus anticis et intermediis leviter 

 asperatis, tarsis valde birtulis. 



Hob. Guatemala, Cerro Zunil (Champion). 



The head and thorax of this species are rather thickly and minutely punctured, the 

 latter less thickly than the former ; and the elytra have series of very fine punctures and 

 the interstices nearly smooth. The thorax is strongly depressed before the base, and 

 has a very faint indication of a central channel in the depression ; a minute impression 

 represents the basal strigse, the transverse impression between being fairly well marked 

 and punctured. The amount of dilatation and the hairy clothing of the front tarsi in 

 the male is well marked in all the species of this section, the three dilated joints having 

 the soles clothed with whitish silky hair and the sides with long black ragged hair. 



12. Dasydactylus longicollis. 



Nigro-subseneus, nitidus, angustus, pedibus rufo-piceis, antennis tarsisque nigris ; capite protboraceque crebre 

 subtiliter punctatis ; elytris punctato-striatis, angustulis, ad apicem aeuminatis, apicibus leviter denticulatis 

 et rotundatis ; prosterno ad apicem acute exciso, sub-bimucronato. Long. 12 millim. J 2 • 



Mas protborace longiore et antice leviter convexiore ; pedibus anticis longioribus, femoribus leviter asperatis, 

 tarsis valde birtulis. 



Eab. Guatemala, Purula (Champion); Nicaeagua, Chontales (Janson). 



This species agrees very closely with D. zunilensis in several of its characters ; it is, 

 however, narrower, the base of the elytra especially, which hence appear very cylin- 

 drical and less narrowed to the apex, and the thorax of the male is also narrower ; the 

 punctuation of the head and thorax is less thick; the elytral series of punctures 

 are distinct at the base, but towards the apex the interstitial punctures are more 

 numerous and here become confused with the striae. The colour above and beneath is 

 blacker than in J), zunilensis. The typical specimens are a male and a female from 

 Chontales. 



13. Dasydactylus subtilior. 



Niger, obscure subameus, nitidus ; capite protboraceque minutissime punetulatis, fere glabris, boc oblongo cum 

 lateribus modice rotundatis ; elytris basi angustulis, sat f ortiter punctato-striatis, interstitiis fere laevibus, 

 apicibus obsolete denticulatis; prosterno ad apicem valde bimucronato. Long. 10-13 millim. tf 2 .
