humeral spot, and another spot near the margin, the second median, extending from 

 the margin to the suture, and united to tlie first by a sutural extension, the third near 

 the apex, sliorter, extending neither to the suture nor the margin ; reflexed margins 

 entirely testaceous ; indistinctly and very minutely seriate-punctate, the punctuation 

 scarcely visible except at the sides ; under-side dark reddish-brown ; legs, epipleural 

 fold, sides of abdomen, and antennee, shining yellow ; the latter with joints 4 to 9 

 strongly seiTate within ; mesosternal process short, broad, rounded in front ; abdo- 

 men finely longitudinally strigose. Long. corp. 2j liu.

STENOSCAPHA, g. n. 



Differs from Liodeina in having the form narrowly oval, the 

 outer edge of the anterior tibiae finely pectinate, and with two unequal 

 spines at the apex outwardly; the four posterior tibiae setose at their 

 outer edge, and bi-spinose at the apex outwardly ; the tibial sj)urs 

 much longer ; the eyes narrower at the sides and above, less approxi- 

 mate above, not obliquely prolonged on the front ; and the middle 

 joints of the antennae triangular, but not serrate within. Mesoster- 

 num, &c., as in Liodema. 



A genus remarkable by the peculiar armature of its tibiae. 



Stejs'Oscapha tibialis, sp. n. 



Elongate-oval, black, sub-nitid ; head in front, and margins (more especially the 

 basal) of prothorax, rufescent ; head and thorax minutely punctured ; scutellum 

 slightly rufescent ; elytra obsoletely seriate-punctate, the intervals finely punctured ; 

 the reflexed margins entirely, and the suture obscurely, red ; the apical half of each 

 red ; under-side reddish-brown ; abdomen pubescent, finely punctured ; mesosternal 

 process elongate, sides parallel, end rounded ; legs and antennae reddish-testaceous.

Allophasia* Maeseuli, s]). n. 



Oblong-oval, smooth, shining ; bright reddish-fernigineous, except the outer 

 eight joints of the antennae, which are dull reddish-brown ; head finely and not 

 closely punctured, strongly depressed between the eyes, front edge of cpistoma 

 elevated, slightly reflexed, rather strongly bi-emarginate, the middle lobe scarcely 

 forming a horn or tooth ; prothorax moderately rounded at the sides, very finely 

 and rather closely punctured, the anterior margin armed at the middle with two 

 rather short conical pointed horns, curved slightly backwardly and outwardly, 

 broadly connected at the base by an elevated ridge, and having behind them a 

 broad and rather deep excavation ; elytra finely punctate-striate, the stria? very faint, 

 the intervals finely and rather closely punctured, and sub-convex behind.
