Hexymus alatus, n. sp. 



d" . Black ; antennas and tarsi of a rather bright-red. 

 Closely covered with small dingy-brown scales ; with numerous 

 stout suberect scales, mostly ochreous or pale-brown, but some- 

 times sooty, interspersed. 



Head with very dense concealed punctures. Rostrum long- 

 and rather thin, slightly decreasing in width from base to 

 antenuce, and then parallel-sided to apex ; on basal two-fifths 

 with coarse concealed punctures and a narrow median ridge, 

 elsewhere shining and with small punctures. Antennse thin, 

 inserted about two-fifths from apex of rostrum ; second joint 

 of funicle almost twice the length of first. Prothora:r rather 

 widely transverse, basal two-thirds almost parallel-sided, apex 

 about half the wddth of base ; with a distinct but obtuse 

 median ridge. Scut ell urn fairly large. Elytra oblong-cordate, 

 distinctly wider than prothorax, base strongly trisinuate, sides 

 gently rounded : with rows of rather large, angular, partially- 

 concealed punctures ; third interstice with a feeble elevation 

 at basal third and a more distinct one at middle, fifth wdth 

 a small one at basal third. Wings present. Under-surface 

 with dense and mostly-concealed punctures, a few of large size 

 at base of metasternum and of abdomen. Metasternum not 

 much shorter than the following segment. Legs long ; femora 

 stout, strongly and acutely dentate, hind ones passing tip of 

 elytra : tibiae thin, somewhat curved at base. Length, 

 7:^-8 mm. 



9 . Differs in having the rostrum somewhat thinner, 

 punctures concealed only about basal fourth, antennae inserted 

 in middle of rostrum, emargination of mesostern^l receptacle 

 longer, and abdomen more convex.

This species should, I think, be treated as an aberrant 

 He i //fju/s, the winged body and consequently longer metaster- 

 num are certainly at variance with all the other species of the 

 genus, but it agrees with all the other characters noted in the 

 revision of the genus /27) The stout scales are irregularly dis- 

 tributed, and are more numerous on the elevated parts than, 

 elsewhere, but they do not form fascicles, except perhaps on 

 the third interstice. On one specimen there are several small 

 sooty spots on the elytra, but on the others the sooty scales 

 are usually scattered singly. On abrasion the prothorax is 

 seen to be densely covered with small punctures, and wdth 

 sparser and moderately large deeply-impressed ones ; the latter 

 appear as small ones through the clothing, but the former are 

 normally concealed.
