TRICHOBARIS.—ANOPSILUS., 41) 
A single specimen (¢) from Coahuila seems to belong to this species. It differs 
from T\. pellicea (tewana) in having larger scales, on both the upper and under 
surfaces. 
CYANOBARIS, gen. nov. 
Mandibles short, decussate ; rostrum (fig. 25a) very short and stout, almost straight, abruptly, transversely 
gibbous at the base, widening outwards, the scrobes rapidly descending, the antenne inserted towards 
the apex, the antennal club ovate; prothorax shortly tubulate at the apex and broadly subtruncate at 
the base ; scutellum transverse, free, prominent ; elytra a little wider than the prothorax, very elongate : 
- pygidium very large, exposed, declivous ; prosternum unimpressed behind the transverse subapical groove, 
the basal portion short; mesosternum long and depressed, the meso-metasternal suture in a line with 
the posterior margin of the middle coxe; anterior coxe exserted, narrowly separated; femora linear, 
sharply dentate, the posterior pair nearly reaching the third ventral suture ; tibie unguiculate ; tarsal 
claws subconnate at the base; body very elongate, narrow, depressed, linear, metallic. 
Type, C. rufiventris. . 
This genus seems to be related to Lichnus, Lacordaire, but it is best placed in the 
section “ Baridiides vrais” of that author. The general shape is that of a Cossonid. 
1. Cyanobaris rufiventris, sp.n. (Tab. XX. figg. 25, 25 a.) 
Opaque, alutaceous, cyaneous, the abdomen rufous and moderately shining; almost glabrous above, the 
punctures on the under surface and legs each bearing a small, hair-like scale. Head densely punctate ; 
rostrum scarcely longer than the head as seen in profile, rugosely punctate. Prothorax very little 
broader than long, gradually narrowing from the base to the tubulate apical portion, the base feebly 
sinuate on each side; closely impressed with coarse rounded punctures, except along the median line. 
Elytra parallel for about three-fourths of their length, flattened down their inner half, the humeri 
rounded; shallowly punctate-striate, the interstices flat, rather coarsely and closely uniseriate-punctate , 
the puncturing becoming coarser and denser towards the base. Pygidium densely, rugulosely punctate. 
Beneath very coarsely and closely, the ventral segments 2-5 more sparsely and finely, punctate. Legs 
rugosely punctate, rather slender. 
Length 64, breadth 2 millim. (9 ?) 
Hab. Mexico, Santecomapan * in Vera Cruz (Sallé). 
One specimen. 
ANOPSILUS. 
Anopsilus, Kirsch, Berl. ent. Zeitschr. 1869, p. 218. 
Balbus, Pascoe, Ann. & Mag. Nat. Hist. (6) iv. pp. 822, 323 (1889). 
The type of Anopsilus is A. bonvouloiri, Kirsch, and that of Balbus, Centrinus 
conicollis, Boh. ‘The species of this genus have large, prominent, subcontiguous 
anterior coxe, and the male of A. conicollis, like that of various other S.-American 
forms, has two short prosternal spines. Cenfrinus suberbificus, suspensus, obniger, 
asphaltinus, capreolus, and oblongus, Boh., probably belong here. ‘They are all 
oblong, polished, black, almost glabrous insects, with a more or less conical 
prothorax, &c.
