34 HETEROMERA. 
Five examples.. §&. nigromaculata is undoubtedly very closely allied to 8. pulchella ; 
but in the large series of the latter before me the common transverse black mark of 
the elytra shows no tendency to become obliterated. In the Guatemalan specimen 
(fig. 10) the lateral spots are extended inwards, and form a common broad median band 
(separated only by a narrow line along the suture) which is widest outwardly; the 
example from Yolos is intermediate between this one and the others. S. negromaculata 
differs from 8. pulchella in the head and thorax being still more finely punctured, the 
apical joint of the antenne shorter in the male, and the elytral interstices convex 
towards the apex, as well as in the different pattern of the elytra. 
47. Statira triangulifer. (Tab. II. fig. 11, 2.) 
Moderately elongate, shining, testaceous, the elytra with a common triangular patch at the base and another 
a little beyond the middle (the latter varying in size, but always broadest at the suture, and sometimes 
extending to the lateral margin, and sometimes narrowly continued along the suture to the scutellar 
patch and posteriorly towards the apex), and the eyes, black or piceous. Head very minutely punctured 
between the eyes, and with a deep setiferous puncture behind each, for the rest smooth, the eyes small; 
antenne testaceous, rather long—the apical joint in the male about equalling joints 7-10 (the latter elongate), 
in the female 8-10, united ; prothorax convex, about as broad as long, the sides immarginate, rounded ante- 
riorly, and strongly constricted behind, the hind angles acute, the basal margin moderately raised, the 
surface thickly but very minutely punctured ; elytra with very shallow intrahumeral depression, widest 
beyond the middle, finely but rather deeply crenate-striate, the interstices flat or feebly convex, the third 
and ninth (and sometimes the fifth) with one or two setiferous punctures towards the apex, and the 
seventh with one at the shoulder, the apices obtuse ; legs and under surface entirely testaceous. 
Length 63-7 millim, ; breadth 13-13 millim. (¢ 9.) 
Hab. Mexico, El Camaron (Sal/é), Tapachula in Chiapas (Hége); British Honpuras, 
Belize, R. Hondo (Blancaneaur); Guatemala, Panzos, San Gerdnimo, Zapote 
(Champion). 
This insect is not uncommon in Guatemala and British Honduras, but is apparently 
rarer in Mexico. WS. triangulifer is allied to S. pulchella, but differs in its narrower 
shape, smoother thorax, longer antenne, and crenate-striate elytra, the latter differently 
marked—in S. pulchella the common basal patch is broader and more transverse, and 
the second band is always broadest laterally, instead of at the suture, as in S. triangu- 
lifer. The head and thorax in S. pulchella are invariably of a reddish-testaceous 
colour, these parts in. S. ériangulifer being uniformly testaceous; the intrahumeral 
depression of the elytra is also more deeply impressed in S. pulchella, and the latter has 
more setiferous impressions on the third interstice. 
48. Statira evanescens. (Tab. II. fig. 12, ¢.) 
Moderately elongate, slightly shining, testaceous or reddish-testaceous, the elytra with the shoulders, a common 
triangular, or elongate, scutellar patch (often connected along the base with the humeral one, in one example 
obsolete), and a median patch on each (more or less transverse in shape, and varying greatly in size— 
sometimes extending nearly to the suture, and connected by a narrow line with the scutellar marking, 
and sometimes entirely obsolete), and the eyes, piceous or black. Head with exceedingly minute scattered
