The eyes of the male are larger and more prominent than usual, their 

 combined width being almost equal to the space between them; on the female 

 their combined width is scarcely half that of the intervening space; on the head 

 of the male the dark hairs form two or three feeble fascicles. The species is close 

 to C. paUidipennU, but the male has the head wider, with larger eyes, impressions 

 different, and small black fascicles, elytra with smaller punctures, and a dark 

 spot on each side near the scutellum; in my table the specimens with immaculate 

 elytra would be associated with ('. pallidipoum, but the spotted ones not with 

 (\ marginivenfris, as the spots are too short and the elytra! punctures finer; the 

 heads of the males are also differently .sculptured. On typical males the pale 

 l)arts are the head (except for a transverse black mark near the base — on some 

 specimens owing to the projection of the prothorax it appears to be at the base' 

 itself), prothorax (except for a large black spot on each side not quite reaching 

 the base), elytra (except for a rounded black spot on each side of the scutellum), 

 scutellum, prosternum, mesosternum, tips and sides of abdominal segments, 

 three to five basal joints of antennie, trochanters, knees, and most of tibioe and 

 tarsi. The typical females are coloured much as the males except that the black 

 part of the head is larger, and that the outer apical angles of the elytra are 

 infuseated, the basal spots are sometimes more extended. On most specimens, 

 of l)oth sexes, there is a dark streak, almcst the entire length of the upper edge 

 of the hind tibia?. 



Var. A. — Seven females, from Mount Tambourine, differ from typical 

 females in having the head entirely pale (on one of them there is, however, a 

 very small medio-basal spot), elytra entirely pale, and more of the antennas 

 dark; they differ from females of pallidipennis in being larger, and with smaller 

 elytral punctures; it would, however, be unsafe to identify specimens of either 

 species from females only. 



Var. B. — A female, from Mount Tambourine, has the head entirely pale, 

 as also the elytra; except for a slight infuscation on each side near the apex, 

 most of its abdomen is pale. 



Var. C. — A male, in the Queensland Museum, has the prothorax and 

 elytra entirely pale ; it seems fairly close to the description of C. xanthochrous 

 and C. tadiyporoides, but its scutellum (as on all the other specimens before me) 

 is pale instead of black.
