﻿Description of Hylocurus Parkinsoniae 145 



M. rudis Lee. and its allies. It is now believed that the latter 

 group is more closely allied to the described species of Hylocurus 

 than to the true Micracis of LeConte of which 31. sitturaJis Lee. 

 is the genotype. Thus in the writer's opinion the genus Micracis 

 Lee, represented by 31. hirtellus Lee, 31. suturolis Lee, 31. meridi- 

 anus Blackm., 31. popidi Sw. and 31. swamei Blackm. and by 

 31. opacicoUis Lee. and 31. namda Lee. of the subgenus Pseudomi- 

 cracis, should stand. 



Hylocurus Eichh. then should include not only the species of 

 that genus described by Eichhoff and by Blandford but also 

 H. parkinsoniae described here\\ath, and the following species 

 hitherto included with 3Iicracis — rudis Lee. hiorbis Blackm., 

 hicornus Blackm., liarnedi Blackm., and Iangsto7ii Blackm. These 

 species agree with Blandford 's rede.scription of the genus in all 

 respects except in the extreme differences between the sexes. 

 Even in this respect Jangstoni shows similar secondary sexual 

 characters but these are not developed to such an extraordinary 

 degree. In liarnedi the sexual differences consist especially in the 

 arrangement and size of certain teeth upon the declivity and in 

 the greater elevation of the ninth interspace in the male. In rudis, 

 hiorhis and hicornus the sexes can be best distinguished by frontal 

 characters, but are also indicated by the slightly coarser sculpture 

 and the greater elevation of the ninth interspace in the males. 



The arrangement then of this division of the subfamily should 

 be as follows: 



A. Antennal club with distinct sutures on the outer face, scape 

 clavate or flattened and subtriangular, funicle 6-jointed. 

 B. Posterior end of elytra drawn out to form an acuminate 

 sutural apex. 



C. Antennal scape club-shaped, with a few short or 



moderate hairs, antennal club with first suture 

 broadly curved ; eyes short oval, widely separated 

 above and beneath ; fore tibiae slightly wider 

 distally, with both edges sinuate, outer edge 

 weakly serrate, distal end with 2-4 marginal 

 teeth. 



Genus Hylocurus Eichhoflf 



CC. Antennal scape flattened, subtriangular, with 

 numerous long hairs, club with first suture angu- 

 late or narrowly curved, eyes large, elongate, 

 more coarsely granulate, contiguous, narrowly 

 or moderately separated beneath ; fore tibiae with 

 outer edge nearly straight. 



Genus 3Iicracis Le Conte 



D. Eyes moderately separated beneath, inner margin 



entire; fore tibiae with sides subparallel, both 

 nearly straight, outer edge entire, terminal mucro 

 wide and large.
