differs in having the elytra subtriangular, being broadest 

 at the shoulders, and the dorsal flattening is much more 

 marked; the elytra also are scarcely striate and the punc- 

 tures larger and more distant, being somewhat like those 

 of C. adonis, sp, n. (PI. IV, fig. 11). 



Compsus zebra, sp. n. (Plate III, fig. 13.) 



5. Integument black, densely clothed with chalky white scaling 

 more or less intermingled Avith pale green scales, the prothorax and 

 el3'tra with narrow stripes that are either bare or clothed with pale 

 green scales; head and rostrum with a continuous median black 

 stripe and occasionally a patch of fuscous scaling behind each eye ; 

 the prothorax with five black stripes, usually edged Avitli a line of 

 green scales ; the elytra with intervals 2, 4, 6, 8 and 10 (abbreviated) 

 black, or partly or completely covered with pale green scaling; 

 the legs with mingled green and white scales, the white predominating 

 on the basal half of the femora and the green elsewhere. 



Head not constricted behind the e^^es, the forehead gently convex 

 transversely and with a shallow median fovea. Rostriivi much longer 

 than broad, markedly dilated at the apex, convex dorsally, with a 

 faint median carina, and a deep oblique furrow on each side, which 

 is so filled up with scaling that it might easily be overlooked ; tlie 

 interantennal area broadly and deeply excavated, the median 

 part bare and shiny. Antennae with the scape reaclmng the hind 

 margin of the eye, slender, rather abruptly clavate, and clothed 

 with narrow green scales and raised setae; the funicular joints in 

 order of length : 2, (I, 3), (4, 7), (5, 6), the apical joints pear-shaped. 

 Prothorax longei' than broad, parallel- sided for two-thirds from the 

 base, then narrowed and with a distinct apical constriction ; the 

 gular margin feebly sinuate ; the dorsum not impressed, but slightly 

 flattened and with a shallow furrow along the median black stripe 

 (sometimes interrupted in the middle), and unevenly set Avith large 

 shallow punctures, which are only distinct on the bare stripes. 

 SciUellum quadrate, with dense green scaling. Elytra with the 

 shoulders slightly sloping and prominent, the sides parallel from there 

 to beyond the middle, somewhat produced and rather abruptly 

 acuminate behind, the apices slightly dehiscent; the dorsal outline 

 slightly rising at the base, then quite fiat to the top of the declivity, 

 which has a slope of 70" ; the striae regular and in pairs, containing 

 rather large round punctures, partly hidden by scaling; the intervals 

 not costate, but 3 and 5 slightly more convex behind, the Avhite 

 intervals much broader than the black (or green), the latter finely 

 coriaceous; the scales small and closely packed, the setae short
