Mazatlan (Forrer), Amula and Venta de Peregrino in Guerrero, Atoyac in Vera Cruz 
(H. H. Snvith), Orizaba (Bilimek, in Mus. Vind. Ces.); GUATEMALA, Duefias, Paso 
Antonio (Champion). 
Not uncommon in Mexico, whence about twenty specimens have been seen. In 
both sexes of this species the connexival segments 1-5 are angularly dilated or spinose 
at their outer apical angles, there being considerable variation in this respect. The 
third antennal joint of the males is also much more thickened in some examples than 
in others. The abdomen is subparallel in the males, rounded at the sides in the females. 
An example from Amula is figured. | 
2. Atrachelus tenuispinis, n. sp. (Tab. XVII. figg. 19, 19@, ¢.) 
3. Moderately elongate, narrow, opaque ; fusco-ferruginous, thickly cinereo-pubescent, the pleura also with 
whitish tomentum ; the rostrum, the cephalic spines, the connexival margins, and the basal joint of the 
-antenne in great part (the other joints broken off), flavous; the legs also annulated with flavous. Head 
armed in front with two exceedingly long, slender, erect spines, these being longer than those on the 
pronotum, the post-ocular portion a little longer than the ante-ocular portion; the basal joint of 
the rostrum reaching slightly beyond the eyes; antenne slender. Pronetum armed with two long 
spines on the disc and with a similar spine at each of the lateral angles. lytra reaching the apex of the 
abdomen. Abdomen with the connexival segments 4 and 5 each armed with a very short spine at their 
outer apical angles (the spine on the fifth segment a little longer than that on the fourth), the other 
segments unarmed, the sixth rounded at the apex. Legs slender, the anterior femora feebly incrassate. 
Length 73, breadth of the abdomen 11 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. Narrower and more elongate than A. cinereus, with the fourth and 
fifth connexival segments only spinose, the cephalic spines exceedingly elongate, the 
post-ocular portion of the head relatively longer (approaching the genus Phorodura in 
this respect), the legs more slender. The antenne are, unfortunately, imperfect.
