﻿Description of Hylocurus Parkinsoniae 143 



The fore tibia is slightly wider toward the distal end, with the 

 two sides sinuate; anterior edge with a few weak serrations; ter- 

 minal mucro long, curved at the end ; distal end obliquely truncate, 

 armed with three submarginal teeth. 



The females vary from 1.7 mm. to 2.3 mm. (allotype, 2.1 mm.) 

 long, 2.6 times as long as wide. The front is .slightly more flat- 

 tened than in the male, very finely granulate-punctate, the trans- 

 verse carina lacking, with the pubescence similar and lacking or 

 nearly so in a transverse line corresponding in position to the male 

 carina ; the pronotum is similar to that of male but with the mar- 

 ginal teeth vsmaller; the elytra are proportionately longer than in 

 the male, slightly wider than pronotum, with the sides subparallel 

 as far as declivity, then broadly rounded, and ending in the acute 

 sutural apex ; surface moderately shining, striae with punctures 

 finer than in male, interstrial punctures and hairs more numerous, 

 both more abundant and the hairs longer toward the declivity, 

 the interspaces not becoming carinate posteriorly; declivity with 

 the margin rounded and the face convex, the suture elevated, 

 granulate and setose, second interspace, flat, unarmed, narrowed 

 posteriorly, third, fifth and seventh elevated, each with several 

 acute granules, ninth subcarinate but not sufficiently so to be 

 visible from above. 



Type — A male, ex dead Parkinsonia; Ray, Arizona, E, A. 

 Schwarz, collector. Allotype, a female, same labels. 



Described from a long series of specimens collected by E. A. 

 Schwarz at Ray, Arizona, and by Hubbard and Schwarz at Fort 

 Yuma, Arizona, all of them being obtained from dead Parkin- 

 sonia sp. Type, allotype and numerous paratypes in the National 

 Museum, paratypes in the author's collection. 



Specimens of this new species were given to the writer for 

 description by Dr. E. A. Schwarz with the comment that they 

 represented a new species of Hylocurus and that in his opinion 

 LeConte's genus Micracis should probably be submerged in Eich- 

 hoff's Hylocurus. The literature was examined with the following 

 results : The genus Hylocurus was described by Eichhoff * in 

 1871 (pp. 133, 134) to include a single species from Mexico — 

 Hylocurus elegans. The same author later (1879,t pp. 298-301) 

 described the genus more fully and added descriptions of two 

 new species — H. discifer from Venezuela and H. alienus from 

 Cuba. The revised description (1. c. p. 298) reads as follows: 



"Head globular, retracted, mentum oblong, narrow toward the 

 base, ligula small, mentum inserted near apex. * * * Antennal 

 funicle 6-.jointed, 1st joint globose, thick, 2nd much narrower, the 

 following transverse, becoming progressively wider, club sub- 

 globose, compact. Tibia sublinear. Tarsal joints 1, 2. 3 eaual."
