STATIRA.—UROPLATOPSIS. 53 
its much smaller eyes (the space behind them being quite broad, instead of narrow as 
in the same sex of S. sulcicrus), longer penultimate joints to the antenne in the female 
(the apical joint, comparatively, not so long as in the same sex of S. sulcicrus), relatively 
narrower thorax, and deeper and still more numerous setiferous punctures on the 
elytral interstices. SS. leptotracheloides, S. sulcicrus, &c., form a small group of species 
which are chiefly confined to North-west Mexico and the adjacent country beyond the 
United-States frontier. S. leptotracheloides closely resembles Leptotrachelus puncti- 
collis, a species of Carabide (cf. Biol. Centr. Am., Col. i. pt. 1, p. 159, t. vi. fig. 18). 
The following species is unknown to me, and owing to the imperfect description 
it cannot be properly placed in the arrangement here adopted :— 
80. Statira tristis. 
Statira tristis, Makl. Act. Soc. Fenn. x. p. 639°. 
Hab. Mexico 1. 
I am unable to identify this insect amongst the large number of Mexican Statire 
before me. The species representing it in the Sallé collection is 8. nigripennis, Makl. 
WS. tristis is described as being very elongate, black, and moderately shining; the 
antenne very robust; the prothorax much rounded at the sides anteriorly, with the 
surface faintly rugulose and very slightly shining; the elytra transversely depressed 
below the base, and with the alternate interstices seriately punctured. To judge from 
Maklin’s description, S. tristis would appear to have the thorax shaped much as in 
S. hirsuta, i. e. rotundate-dilate anteriorly; the thorax of S. pueblensis cannot be thus 
described. In the structure of the antenne and in the elytral sculpture (as given by 
-Maklin), S. tristis resembles S. pueblensis. 
UROPLATOPSIS. 
Last joint of the maxillary palpi elongate-triangular, that of the labial palpi narrow and ovate and with its 
apex truncate ; ligula moderately prominent, rounded on each side, and emarginate in the middle in front ; 
mentum trapezoidal, transverse ; outer lobe of the maxille rather narrow; mandibles simply uniden- 
tate at the apex; labrum very large and prominent; antenne with joints 3-10 large and more or less flat- 
tened and dilated, very broadly so in some species, and angularly widened on each side towards their apex, 
7 and 8 the widest, 11 very long in both sexes, and usually about half the width of the apex of 10; head 
narrow, abruptly constricted into a neck behind; eyes convex, small, or only moderately large, somewhat 
distant from the base of the head ; elytra with or without an opaque velvety lateral patch; anterior coxe 
strongly exserted, narrowly separated, the prosternum raised between them ; metasternal episterna almost 
unimpressed, and without well-defined groove along the inner margin ; tibiw without distinct spurs.
