30 HETEROMERA. 
with prominent front angles, and the surface finely scabrous and opaque; and the 
elytra rather deeply punctate-striate. The apical joint of the antenne varies a little 
in length in both sexes. The variety 8 was collected by myself in numbers at Capetillo ; 
in some of these the elytral interstices are obsoletely punctured at the apex. The 
species varies from 8-11 millim. in length. 9. nigrosparsa differs from S. rugicollis 
and S. guatemalensis in its more finely scabrous thorax and ungrooved tibie, and from 
the former in the much less numerous setiferous impressions on the elytra; the two 
last-mentioned species having sulcate tibie they are placed towards the end of the 
genus. 
39. Statira penicillata. (Tab. II. fig. 3, 3.) 
Closely allied to S. testacea, and differing as follows:—Reddish-testaceous ; the prothorax not so densely 
scabrous, slightly shining ; the elytral interstices strongly convex (except at the base), the first with about 
eight (four at the base and four at the apex), the third and fifth each with twelve or fourteen (scattered 
between the base and apex), the seventh with one or two (at the shoulder), and the ninth with four or 
five (towards the apex), deep setiferous punctures; the posterior tibie in the male with a dense brush of 
very short hairs on the inner side near the base ; the rest as in S. testacea. 
Length 9 millim.; breadth 24} millim. (¢.) 
Hab, Mexico, Jalapa (Hége). 
This is the only species of the genus known to me possessing the peculiar above- 
described sexual character on the posterior tibie in the male. Unfortunately our male 
examples of S. testacea are in a mutilated condition and without hind legs; they may 
or may not possess this character. SS. pentcillata differs, however, from S. testacea in 
the much more numerous setiferous impressions on the first, third, and fifth elytral 
interstices, and also in all the interstices being very convex. A single male example. 
40. Statira alternans. 
Elongate, subparallel, subopaque, reddish-brown, the elytra obscure testaceous and slightly shining. Head 
densely and rugosely punctured, the eyes large ; antenne long and stout, ferruginous, the apical joint in 
the male about as long as joints 5-8 united; prothorax transverse, broad, the sides distinctly margined 
from the base to the apex, a little rounded before the middle, slightly oblique in front, and strongly 
constricted behind, the hind angles very acute, the basal margin sharply raised, and at the sides shallowly 
grooved within, the disc a little flattened behind, the surface finely scabrous ; elytra with shallow intra- 
humeral depression, long, rather broad, parallel, closely and finely punctate-striate, the interstices flat, 
the first, third, fifth, seventh, and ninth each with a row of rather closely placed deep setiferous punctures, 
extending from the base to the apex, the apices obtuse ; legs testaceous, rather stout, somewhat thickly 
punctured and clothed on all sides with short hairs, the tibiee not grooved on their outer edge. 
Length 11 millim.; breadth 3 millim. (¢.) 
Hab. Mexico, Tepansacualco (Sallé). 
A single immature male example only, but undoubtedly distinct from the other 
species here enumerated. In many respects S. alternans resembles S. sulcicrus. It 
differs as follows:—The tibia are not grooved on their outer edge; the antenne (<¢ ) 
are longer, and have a longer apical joint; the eyes are larger; the thorax is more
