Like the preceding, this apparently common species of Trimerotropis is absent from 

 the collections now being studied. 



5. Trimerotropis townsendi, sp. n. 



A rather small, but moderately robust species, the prevailing colour of which is brownish-ferruginous. Hind 

 tibiae bright coral- red, the tegmina inconspicuously banded, the insect in this respect somewhat resembling 

 T. modesta, Bruner. It is also related to T. prceclara, McNeill, near which it should be placed in 

 his synoptic table of the species of the genus Trimerotropis. 



Head a very little narrower than the front edge of the pronotum ; eyes somewhat prominent in the male, less 

 so in the female, in both sexes shorter than the cheeks below them ; vertex not quite so broad as the 

 shortest diameter of one of the eyes, rather deeply sulcate, with prominent bounding carinas and usually 

 provided with a fairly strong longitudinal median carina ; lateral foveolse equilaterally triangular, much 

 deeper and more pronounced in the male than in the female ; frontal costa with the walls quite prominent, 

 expanding between the antennas and again towards the clypeus, which latter it does not quite reach, 

 rather strongly and broadly sulcate throughout the greater part of its length, the sulcus most pronounced 

 in the male, in which sex there is a deep V-shaped depression at its upper extremity just before the 

 sulcation of the fastigium. Antennas rather heavy, nearly ( $ ) or quite ( 3 ) as long as the hind femora. 

 Pronotum strongly rugose (reminding one of the sculpturing of this part in some of the smaller species 

 of Eippiscus), in the female sometimes provided with a series of rounded tubercles on the disc of the 

 posterior lobe, short ; its hind margin somewhat obtuse in the female and at a right angle in the male, the 

 lower posterior angle broadly rounded and without a tooth-like projection. Tegmina a little narrower 

 than in some of the other red-legged species, profusely veined on the basal three-fifths and considerably( $ ) 

 or only slightly surpassing ( $ ) the tip of the abdomen. Hind femora moderately robust. 



General colour above brownish-ferruginous, the tegmina provided with two inconspicuous dusky bands, one 

 sub-basal, the other near the middle, beyond this with a few irregularly-arranged fuscous blotches. 

 Wings with the disc pale yellow, crossed about the middle by a moderately wide fuscous band, the apical 

 third a trifle clouded or smoky ( $ ), or with the apex also fuscous, and the fuscous space separated from 

 the band by a wide, much paler portion. Hind femora provided externally with a prasapical fuscous 

 band and indications of another band on the upper edge midway towards the base ; internally with two 

 pale testaceous bands, separated by one of black, the knee and greater part of basal half also black. 

 Hind tibias and tarsi bright coral-red. Abdomen brownish above, yellowish below. Antennas dark 

 ferruginous, becoming black beyond the basal third. 



Length of body, <J 18, $ 25 ; of pronotum, tf 4-2, $ 5; of tegmina, S 20, $ 23; of hind femora, 6 11-75, 

 $ 13 millim.
