258 REVISION OF THE GENUS PAROPSIS, 



rugulose becoming gradually coarser from the middle of the disc 

 towards the margins, and its hind angles are quite rounded off. 

 The seriate punctures of the elytra run in distinct, but not 

 strongly impressed, striae; the interstices are flat; and there is 

 generally an unpunctured more or less interrupted wheal-like 

 space between the lateral stria and the confused marginal punc- 

 turation. The antennae are elongate and somewhat robust, but 

 decidedly filiform, all the joints (except the 2nd) much longer 

 than wide, the 3rd joint considerably longer than the 4th. The 

 basal joint of the 4 anterior tarsi of the male is dilated compara- 

 tively feebly (with its sides but little rounded) and the apical 

 ventral segment scarcely differs in the sexes. . The size is 

 variable (long. 4-5 lines). The head varies from entirely testa- 

 ceous to testaceous with the vertex and a longitudinal line 

 (which is bifid in front) black. The prothorax varies from 

 entirely testaceous, through forms in which there are obscure fuscous 

 markings, to one {ornaticollis, Chp.) in which there are three 

 large black spots placed transversely across the disc and then to 

 forms in which these spots enlarge and coalesce (typical lujnea) 

 till in the extreme (that I have seen) the prothorax is black with 

 the lateral and front margins testaceous. The scutellum varies 

 from testaceous to black. The markings of the elytra (when 

 present) have the apparently constant character of consisting of 

 lines or vittse continuous from close behind the base to the apex 

 (or almost to the apex). The elytra vary from entirely testaceous, 

 through a form in which the humeral calli, the strise and all the 

 punctures are fuscous, and another in which also all the interstices 

 are fuscous and all the strife and punctures black (only the lateral 

 margin being testaceous), to one (typical ornaticollis) in which 

 the interstices are alternately black and testaceous. The under 

 surface varies from testaceous to black, the legs from testaceous 

 to black (except the knees, tarsi and apex of tibiae). The antennae 

 are testaceous, in many examples fuscous or blackish near the 

 apex. In general the darkly coloured specimens are males and 

 the light ones females. The species is common in Tasmania and 

 Victoria. I have taken it, but not commonly, in N.S. Wales.
