Australian and Tasmanian Cryptocephalides. 451 



Cadmus quadrifasciatus, n. sp. 

 (Plates XXIV, XXV, figs. 103, 104, 153.) 



(^ . Elongate-oblong, subopaque. Black ; apex and sides of 

 prothorax (except the extreme margins), four incomplete elytral 

 fascioe, front sides of prosternum, apex and intercoxal process of 

 abdomen, and basal half of tibiae flavous ; second— fifth joints of 

 antennas reddish. 



Upper- surface (including scutellum) densely and coarsely punctate, 

 the punctures more or less angular. Head feebly longitudinally 

 impressed ; eyes larger and closer together than usual. Antennae 

 considerably longer than the body, second joint less than one-third 

 the length of third, fifth distinctly longer than sixth. Prothorax 

 about once and one-half as wide as long ; oblique impressions 

 feeble; margins rather narrow and crenialate. Scutellum suboblong, 

 base indistinctly notched, apex truncate, ridged along middle. 

 Elytra oblong, subhumeral lobes small, interstices acutely elevated, 

 the alternate ones irregular across middle. Intercoxal process of 

 prosternum wide, front thin and entire, hind apex very obtusely 

 rounded. 



Length 4| mm.

The elytral fasciae should perhaps be regarded as trans- 

 verse spots, they are almost equidistant from each other, 

 the three first distant about two interstices from the 

 suture, the fourth on the apex itself and just perceptibly in- 

 terrupted at suture and terminated almost on the margin ; 

 the second extends over the greatest, whilst the first 

 extends over the shortest space ; the outlines of all are 

 very irregular although sharply defined. 



In appearance somewhat resembling Cadmus luduosvs, 

 Chp., but (apart from colour markings) of smaller size, 

 elytra much more acutely costate, the prothoracic punctures 

 rougher and the abdominal segments much less curved. 

 It is also evidently allied to Paracadmus maculatus, Blackb., 

 but besides the numerous differences in colour, some of 

 the elytral carinas are distinct from base to apex, whilst 

 in maculatus the elytra are described as "postice suhcostatis." 



There are two female specimens before me (both from 

 Victoria) which with some doubt I refer to this species ; 

 they differ in having the prothorax pallid except for a 

 wide transverse marking (much as in many of the varieties 

 of crucicollis), the elytral fasciae wider and larger, with the
