STRONG YLOTES.—TRACHYMEROPSIS. 207 
2. Strongylotes parallelus, sp. n. (Tab. XII. figg. 5, 5 a.) 
Elongate, narrow, cylindrical, flattened above, shining, black, the antenne in part and the tips of the tarsi 
ferruginous ; beneath thickly, above sparsely, clothed with rather coarse, oblong, whitish scales. Head 
finely punctate; rostrum slender, almost straight, about as long as the head and prothorax, sparsely, 
finely punctate, the antenn:e inserted behind the middle, joint 1 of the funiculus as long as 2-4 united, 
the club ovate. Prothorax longer than broad, narrowed at the apex, the sides parallel thence to the 
base, the base feebly bisinuate ; closely punctate, except along a narrow smooth space down the middle. 
Elytra parallel, about twice the length of the prothorax, and of nearly the same width, subtruncate at the 
base, and conjointly rounded at the apex, leaving the pygidium narrowly exposed; punctate-striate, 
the interstices flat and irregularly punctate. Beneath closely, the ventral segments more sparsely, 
punctate ; prosternum slightly depressed down the middle, the anterior cox narrowly separated. Legs 
slender; femora sublinear, unarmed, pilose beneath; tarsi narrow, the third joint strongly bilobed, the 
claws connate at the base. 
Length 54, breadth 1 millim. (9?) 
Hab. Mexico, Ciudad in Durango, 8100 feet (Forrer). 
Two specimens, both somewhat abraded. This species seems to be nearly related 
to S. brachialis, which also has narrow tarsi, thus differing from S. squamans and 
S. lemniscatus, Boh. 
TRACHYMEROPSIS, gen. nov. 
Mandibles straight on their inner edge; rostrum cylindrical, almost straight, as long as, or a little longer 
than, the prothorax, the scrobes gradually descending ; eyes large, distant ; prothorax subcylindrical to 
near the apex, without ocular lobes, bisinuate at the base, the median lobe short and truncate; scutellum 
transversely subquadrate; elytra long, not wider than the prothorax; pygidium not visible ; prosternum 
shallowly depressed down the middle anteriorly, the broad intercoxal portion flattened ; mesosternum 
almost on a level with the prosternum, extending broadly backward between the middle coxe ; ventral 
segments 1 and 2 long, subconnate ; anterior legs moderately long, the others shorter, the posterior 
femora barely reaching the third ventral suture ; femora stout, abruptly excavate near the apex beneath, 
unarmed; tibie short, slightly sinuate, the anterior and intermediate pairs strongly, the posterior pair 
more feebly, unguiculate ; anterior and intermediate tarsi with joints 2 and 3 broadly dilated in both 
sexes, but much more strongly so in ¢ than in 9; tarsal claws minute, connate; body narrow, 
elongate-elliptic, polished, and in great part glabrous. 
Type, 7. palmipes. 
The type of this species is very like Azygides stygius, Pascoe, from Parana (which 
has a single tarsal claw, and was placed by its describer near Parallelosomus), but 
belongs to the “ Nertides,” as defined by Lacordaire, near Trachymerus. It has the 
anterior and intermediate tarsi greatly dilated in both sexes, but more strongly so in 
the male than in the female. The more widely separated anterior coxe, the sub- 
connate first and second ventral segments, the short posterior legs, the minute tarsal 
claws, and the subcylindrical shape of the body, separate Trachymeropsis from 
Nertus. 
1. Trachymeropsis palmipes, sp. n. (Tab. XII. figg. 6, 64, 3.) 
Very shining, black, the antenne fusco-ferruginous; the elytra and under surface with scattered coarse white 
scales, those on the elytra condensed into a short streak at the base of the suture, a few small spots on 
the disc exterior to it, an irregular, interrupted post-median fascia, and several small spots near the apex ;
