3839. Zeagyrtes vitticollis sp. nov. 



Oblong-oval, only moderately convex, nitid ; head, thorax, and basal 

 joint of antennae fusco-testaceous, the elytra more or less so near the apex, 

 the thorax with a broad dark streak along the middle ; elytra and remain- 

 ing joints of antennae fusco-piceous or nigrescent, the former sometimes 

 paler near the base ; legs more or less infuscate ; pubescence elongate and 

 suberect, principally dark, but with some grey hairs near the base, on the 

 middle, and across the top of the hind slope ; these, however, do not form 

 fasciae. 



Head nnu'h narrowed in front of the large, prominent, obliquely oval 

 eyes, distantly punctate. Thorax about a third broader than long, with 

 fine lateral margins, more curvedly narrowed anteriorly than near the base, 

 which is slightly rounded in the middle, with subrectangular angles, the 

 apex truncate ; disc moderately coarsely and irregularly punctured. Scu- 

 tellum subtriangular. Elytra of the same width as thorax at the base, 

 tbrice its length, with singly rounded apices, so that the pygidium is some- 

 times exposed ; sutural striae distinct, their sculpture consists apparently 

 of fine transverse serial punctures and lines. 



Antennae longer than head and thorax, rather slender, bearing nume- 

 rous outstanding dark setae ; basal joint rather longer than the elongate 

 2nd. 3rd a little shorter than 4th, 5th and 6th about equally slender ; 

 remaining joints, except the rather shorter and more slender 8th, longer 

 and rather thicker than the 6th. 



Tibiae slender, elongate, and finely setose, the posterior straight, the 

 others slightly arched, the hind pairs finely bispinose at the extremity. 



Underside shining, dark fuscous, with slender, grey pubescence. An 

 terior coxae prominent and contiguous. 



Length, 2^ mm. ; breadth, l^^mm.
