pubescence, pro thorax finely punctate with a median bare hnpunctate 

 line, from which a transverse pubescence; elytra more coarsely 

 punctate with horizontal ridging. 



Head with interocular space a little more than half width of head, 

 a median bare line down front, eyes emarginate at antennal sockets, 

 pu notation dense and becoming coarser in lower part under a dense 

 white pubescence, labrum reddish brown. Antennae reddish brown, 

 with outer joints often darker, extending below humeri, outer joints 

 wider, seventh joint long. Prothorax wider than long, strongly 

 convex, lateral sides curved and anteriorly projecting around eye; 

 a median bare line and some round bare spots on disc, otherwise 

 densely and rather finely punctate, a fine white pubescence extending 

 from median line horizontally, and often thicker on sides. Scutellum 

 shining piceous with a few white hairs. Elytra widest at humeri, 

 tapering toward apex, where sides are pinched in and end in a sharp 

 prolonged tip, not divergent; not depressed about scutellum but 

 evenly convex, a short intrahumeral sulcus, humeri prominent; 

 punctation coarser than on pronotum and not so dense with horizontal 

 ridging between rows of punctures, sometimes a bare line parallel to 

 suture near apex; surface shining with a bronzy lustre and thinly 

 covered with pale appressed pubescence. Body beneath with thick 

 white pubescence, especially heavy on sides, legs dark reddish brown. 

 Length 8-10 mm.; width 3.6-4.5 mm.

Remarks: This is another of the species with prolonged tips to the 

 elytra. The two South American species, G. aeneipennis Baly and 

 G. Jascicularis Baly, both have less pronounced and not so long tips 

 at the apex of the elytra. The North American species G. cryptica 

 Say has the tips more marked in the male and is of a reddish-brown 

 color with scalelike pubescence and coarser punctures, especially on 

 the pronotum. Glyptoscelis cryptica also has simple claws. Unlike 

 these other species the tips of 6. chontalensis are not divergent but 

 united into one prolonged apex.
