This genus is also allied to Ghelostoma and Heriades^ but differs 
by the four-jointed maxillary palpi. It approaches Andronicus^ but 
differs in the shape of the labial and maxillary palpi, and also in the 
structure of the % antennae, which is again remarkable in this genus; 
the abdomen is neither elongate or cylindric. Two species, both males, 
are at present known to me. 
1. A. pilosifrons, n. sp. 
Male. —Head black, minutely punctured, clothed with long yellow¬ 
ish-white pubescence, which is very dense on the face ] scape of the 
antennae black, the flagellum rufo-testaceous beneath, rufo-piceous above. 
Thorax convex above, densely and flnely punctured, black, shining, 
densely and uniformly clothed above and beneath with rather long 
yellowish-white pubescence; tegulae rufo-piceous, shining. Wings 
hyaline; nervures blackish. Legs simple, black, shining, sparsely 
clothed with pale hairs; tibial spurs testaceous; apical joints of the 
tarsi ferruginous, claws bifld, tipped with black. Abdomen subovate, 
black, shining, finely punctured, convex above, rather flat beneath, 
apex incurved and pointed ; each segment having an apical marginal 
fringe of short white pubescence, sides of the segments clothed with 
pale hairs; on each extreme side of the sixth segment posteriorly a 
stout acute tooth; apical segment narrow, pointed, carinated above ; 
beneath, the second ventral segment has on its disk a rather large, 
transverse, obtuse projection; the last segment forcipate, rufo-testace¬ 
ous. Length 4 lines. 
Female. —Unknown.

2. A. producta, n. sp. 
Male. —Head black, flnely and densely punctured; face on each side, 
the cheeks and the vertex sparsely clothed with rather short whitish 
pubescence; antennae black, the flagellum tinged with rufo-testaceous 
in front and towards their tips. Thorax black, flnely and densely 
punctured, subopaque, clothed with whitish pubescence which is short 
on the disk above and long on the pleura, scutellum and sides of the 
metathorax ; tegulae black, shining. Wings subhyaline; nervures fus¬ 
cous. Legs black, sparsely clothed with short pale hairs; tarsal claws
