HAB. Nogales, Arizona ; a single example was captured be- 

 neath an oak tree in September. 



Clu-logyiius Hal. 



A'coc/iclogyiiiis of Bull. I is synonymous with this, as a com- 

 parison of European species shows, and the characters of the 

 mouth parts are as described by me under that name. It is at 

 once separable from Anteoii by the partially extensile chelae and 

 the different position of the articulation of the fourth and fifth 

 tarsal joints, to which this mobility is due. Chciogymis at pres- 

 ent includes insects with great differences in structure and will 

 unquestionably be itself broken up. 



Table of Species described. 



1 (2) Apical joint only of the antennae dark C. liisns. 



2 (i) More than one antennal joint dark. 



3 ( 4 ) Coxae mostly dark, pronotum with some transverse 



rugulosity C. funcstus. 



4 (3) Coxae altogether pale C. mclanacrias 



I. C/iclogyiiiis fiiiicsfus sp. nov. 



Black, the basal joints (usually about four) of the antennae 

 ferruginous, the apical ones black. Some of the basal joints may 

 be more or less darkened, the nunaber of those that are red is 

 not constant and the red often gradually merge into the dark 

 apical ones. The front femora are sometimes pale, but may 

 be nearly black, the middle and hind ones are generally black or 

 at least pitchy-brown, and their tibiae are also dark, but noticeably 

 pale on the basal part to a greater or less extent ; hind coxae 

 always black or dark, except that the extreme apex may be pale. 

 ?klandibles yellow, the teeth dark ; neuration yellow, stigma dark 

 fuscous. 



Head and face cjuite dull, very densely and minutely sha- 

 greened or rugulose, the antennae with the flagellum subclavate, 

 the scape about as long as the three following joints together, 

 second joint subequal to third, which is slightly longer than the 

 fourth, the fifth decidedly wider than the preceding, but none of 

 the flagellar joints are transverse. Pronotum with some extreme- 

 ly fine transverse rugulosity ; the mesonotum more or less shin- 

 ing, at least never dull like the head, and with at most a few
