498 NKW SPECIES OF AUSTRALIAN COLEOPTERA, xi., 



Elytra rather narrow; with very dense, rather small, sharply 

 defined, non-confluent punctures. Length, 8 mm. 



//rt,6._N.S.AV.: Forest Reefs (A. M. Lea). 



As the third joint of the antennfe is almost once and one-half 

 the length of the second, the species should be referred to "A A," 

 in Blackburn's table, and, in that group, it would be associated 

 with Z. murrayi and Z. suhnigafa, with which it has little in 

 common. The antennae are thin and extend almost to the tip of 

 the elytra, but I do not regard them as "extremely slender" for 

 the genus. Z. helnisi* which is so distinguished in the table, 

 certainly has thin antennfe, but they are not particularly long, 

 in fact they are distinctly shorter than in many species of the 

 genus, and with the second joint quite unusually short. The 

 eyes are almost as large as in Z. 2^ictico7'ni8, but are not quite so 

 close together, and the elytral punctures are different, being 

 somewhat similar to those of Z. melanoptera; but the two species 

 are otherwise very different. From Z. jyctHicolor^ it differs in its 

 entirely dark femora, antennae with the joints pale at the base, 

 prothorax more noticeably pubescent, and punctures on same 

 slightly larger. 



ZONITIS XANTHOSOMA, n.Sp. 



Flavous, antennae (two or three basal joints excepted) black; 

 palpi, tarsi, and sometimes tips of tibiae more or less infuscated. 

 Elytra with dense and very short pale pubescence, rest of upper 

 surface almost glabrous. 



Head rather short, widest close to base, almost evenly convex; 

 from clypeal suture to apex of labrum about half as long as from 

 same to neck; with clearly defined, and not very large punctures, 

 somewhat irregularly distributed. Eyes widely separated and 

 not very large. Antennae rather thin, extending almost to apical 

 segment of abdomen, third joint of antennae not much longer than 

 second, Prothorax not quite as long as the greatest width, which 

 is distinctly nearer apex than base, sides moderately incurved 

 between middle and base, apex comparatively wide and distinctly 

 incurved to middle; with rather small punctures, fairly numerous
