DASYDACTYLTJS. 21 



Mas prothorace convexiore ; pedibus anticis longioribus, femoribus anticis leviter asperatis, tarsis valde 

 hirtulis. 



Hab. Mexico, Toxpam, San Andres Tuxtla (Salle), Cordova (Hoge); Beitish 

 Hondueas, Belize, R. Hondo (Blancaneaux). 



This species bears a very close resemblance to D. thoracicus, but the elytra are not 

 so pointed towards their apex, and are not truncate ; the prosternum is decidedly and 

 strongly bimucronate at the apex of the process, and also differs in other respects. It 

 is really more nearly allied to I), hondoensis and D. picipes, three species extremely 

 difficult to discriminate ; the head and thorax in I), subtilior are, however, so very 

 finely punctured that they appear glabrous under an ordinary pocket-lens of an inch 

 and a half focus. D. subtilior is also larger, blacker, and has a longer thorax than 

 D. hondoensis ; and the thorax of the male narrows in front, where it is narrower than 

 at the base. 



In the specimen from Cordova the interstices of the elytra are punctulate ; but in 

 others, as the one from Tuxtla ( $ ), they are nearly smooth, though finely rugulose ; 

 in the British Honduras specimens all the punctures are more obsolete, so that I do not 

 think any good characters can be drawn from the elytral punctuation. I think, however, 

 that the very fine punctuation of the head and thorax is constant. 



14. Dasydactylus cribratus. 



Niger, subtus cum pedibus pieeus ; capite protboraceque crebre distincte sat fortiter punctatis, boc oblongo ; 



elytris fere cylindricis, punctato-striatis, apicibus subtiliter denticulatis ; prosterno punctulato, processu 



apice sub-bimucronato. Long. 6-9 niillim. rf $ • 

 Mas prothorace convexiore, basi latiore, femoribus anticis et intermediis asperatis ; tarsis anterioribus minus 



late dilatatis, hirtulis, subtus albidis. 



Hab. Mexico, Teapa in Tabasco, Tapachula in Chiapas (Hoge). 



A species allied to D. hondoensis, but easily distinguished by the long thorax and 

 punctulate prosternum. The thorax is longer than in any species yet described, except 

 D. longieollis. The punctures on the prosternum are large and scattered ; the process 

 is smooth but longitudinally furrowed and uneven. The legs of the male are long and 

 as in D. hondoensis ; but the front tarsi are much less widely hairy, and are narrower. 

 The thorax is less shining than in its near allies, owing to the punctures, though 

 distinct, being thick. Four specimens were captured by Herr Hoge during his second 

 expedition to Mexico. 



15. Dasydactylus hondoensis. (Tab. I. fig. 10, c? .) 



Niger, subtus cum pedibus pieeus, antennis, geniculis tarsisque nigris ; capite prothoraeeque subtiliter parce 

 punctatis; elytris punctato-striatis, apicibus rotundatis et angustatis, stria suturali ad apicem valde 

 impressa ; prosterno exciso, apice sub-bimucronato. Long. 10 millim. <$ $ . 



Mas prothorace convexiore, antice latiore ; femoribus anticis et intermediis asperatis, tarsis nigro-hirtulis.
