﻿DESCRIPTION OF HYLOCURUS PARKINSONIAE N. SP. 

 With Revisional Notes on Hylocurus Eichh. and Micrais Lee. 



By M. W. Blackman 



Description of the adult male: Dark reddish-brown in color, 

 2.17 to 2.4 mm. long, about 2.5 times as long as wide. 



The front of the head is convex-above, opaque, densely and 

 coarsely granulate-punctate with numerous (often abraded), cla- 

 vate, cinereous bristles, directed anteriorly ; with an arcuate, trans- 

 verse, granulate carina separating the lower portion, which latter is 

 transversely impressed, smoother, subopaque, with slightlj'' longer, 

 more slender hairs directed diagonally downward. The eyes are 

 short oval, moderately coarsely graiuilate, with the inner margin 

 entire. The antennal scape is short, clubshaped, curved or twisted, 

 with a few rather short hairs ; the funicle 6-jointed, 1 3/5 times 

 as long as the scape, the pedicel wide, comprising more than 1/3 of 

 length of funicle, distal segments slightly wider ; the club short 

 oval, first segment about 1/3 length of club, first suture very 

 faintly sinuate, second similar and nearly parallel. 



The pronotum is 1.03 times as long as wide, widest behind the 

 middle, with the sides behind subparallel ; moderately rounded in 

 front; anterior margin with low blunt serrations; asperities of 

 the anterior area low, broad, moderately coarse; posterior area 

 reticulate, subopaque, granulate-punctate, with very short, fine 

 hairs. 



The elytra are wider than the pronotum ; 1.5 times as long as 

 wide, with the sides subparallel (slightly widened posteriorly), 

 abruptly narrowed at the declivity, with a prominent sutural 

 apex ; surface rather feebly shining, nearly glabrous ; punctate 

 striate, with the striae deeply impressed posteriorly, with the punc- 

 tures moderately coarse anteriorly but progressively coarser 

 toward the declivital summit; interspaces narrower, with only a 

 few punctures, shining anteriorly, subopaque near declivity, feebly 

 convex anteriorly, but becoming carinate posteriorly and each 

 ending at the declivital margin in a short, blunt tooth-like pro- 

 jection. Declivity abrupt, oblique, the face convex, striae punc- 

 tured, the punctures coarse near the margin but rapidly becoming 

 finer toward the apex; suture elevated, granulate, with short, stiff 

 hairs, second and alternate interspaces flat, unarmed, with a few 

 hairs only near declivital margin ; third and alternate interspaces, 

 more or less elevated, each with a few stiff hairs, third with from 

 two to five small teeth or acute granules ; fifth and seventh with 

 one or more, ninth with the carina extending as far back as the 

 base of the sutural apex, and, as seen from above, separated from 

 this by a distinct notch.
