LANGDRIIDAE 36b 



A. gagaticeps is allied to and resembles A. cuneiformis, Crotch, 

 with which it agrees in having the thorax of a whitish-yellow 

 colour, rather short and convex, but the club of the antennae 

 in .4. onici fori)) is is even broader, and in A. gagaticeps the elytra 

 are green. In both these species the elytra are very distinctly 

 narrowed from the shoulders to the apex, but in A. cuneiforrniSj 

 of which the type is before me and an example which I refer 

 to it from Sarawak (Wallace) the elytra are blue, and the latter 

 is larger, and the body beneath is red.

8. Dasydaciylus, Gorham, Biol. C. Am., Vol. VII, p. 14, 1887. 

 The Dasydactyli are exceedingly neat and graceful members 



of the Languriides, peculiar to the New World; having rather 

 long legs, the front pair usually considerably lengthened in the 

 males, and with the front tarsi widened and more hairy in that 

 sex, and the front femora roughened on their inner sides in the 

 males. More than 20 species are recorded in the Biologia from 

 Central America, and they are also known to me, but mostly 

 undescribed for want of material , from Colombia. The species 

 are very closely allied, and the one now described, and which 

 is the first species I have recognised as new since the completion 

 of that work, is very nearly related to more than one species 

 here described. The chief points to be attended to in the species 

 of this genus are the punctuation of the head and thorax , the 

 relative length of the latter, and its development in the male 

 sex, the length and build of the antennae , and the form and 

 sculpture of the elytra. The colour is generally black or pitchy 

 or aeneous, and is not a safe character, nor do I think the size 

 is much to be relied upon.
