208 MEMOIRS OF THE QUEENSLAND MUSEUM. 



There is a single specimen with the elytra almost entirely dark, the hind 

 femora and coxa? and part of the metasternum dark, and the interociilar fascia 

 distinct; another ha.s the head entirely pale, the elytra entirel}^ dark, and parts 

 of the middle and hind legs and of the metastemum dark. 



So many females of this species have been before me that I think it almost 

 certain that I have seen males, but not associated them with the species. If the 

 male is reallj' before me it may be C. elegans, of which only the male is known, 

 and which has remarkable front tarsi. 



CARPHURUS PISONIffi sp. nov. 

 $ Flavous; two spots near base of head (sometimes conjoined) and 

 metastemufti black, five to seven apical joints of antennce inf uscated. With 

 sparse white pubescence and straggling black hairs. 



Head rather wide and irregularly impressed between eyes, with two 

 oblique median elevations ; with irregular punctures, becoming crowded near 

 eyes. Antennae moderately long and scarcely serrated. Prothorax slightly 

 longer" than greatest width (near apex), a shallow open depression near base; 

 with a few scattered punctures. Elytra almost twice the length of prothorax, 

 and much wider at base, each side near apex with a deep semicircular notch, 

 the anterior end marked by a subtriangular portion of the elytron, the posterior 

 by a long acute spine directed forwards and outwards; with dense and sharply 

 defined punctures, suddenly terminated near apex. Basal joint of front tarsi 

 with a small black comb. Length, 3-4 mm. 



Hah. — Northern Queensland (Blackburn's collection) ; Cairns district, in 

 abundance on sticky seeds of Pisonia hrunonia^na (F. P. Dodd). — Type, /. 11938 

 in South Australian Museum; cotype, C/3341 in Queensland Museum. 



Allied to C. cristatifrons, and with similar elytral armature, but the head 

 bimaculate and the elytra not; the head from the side appears evenly convex, 

 whereas on cristatifrons the strong ridges, abruptly terminated in front, give a 

 very different appearance; its head also has much larger and deeper impressions 

 than the present one. The impressions between the eyes are not very deep ; 

 there are two oblique elevations between them, and these, with a feeble longi- 

 tudinal interocular elevation, appear to form a V (or feeble Y) '■> ^ach fork of 

 the V touches one of the black spots. The spines on the elytra are broken on 

 many of the specimens, and when about half of each is left the notch from some 

 directions appears as an almost circular hole; the part beyond the spines is 

 sometimes of the same colour as the rest of the elytra, but is usually of a lemon- 

 yellow colour, and is impunctate. The abdomen is of a somewhat redder tone 

 than the other pale parts. Under the microscope the tarsal comb is seen to 

 consist of ten or eleven teeth. More than one hundred specimens were removed 

 from the seeds, but all are males.
