partially concealing third and fourth, and with a black 

 outer comb. Length ( d , 9)> 4-5*5 mm. 



9 . Differs in having the head smoother in front, 

 antennae slightly shorter and thinner, elytra more dilated 

 posteriorly, and second joint of front tarsi similar to the third. 



Hab. — Victoria: Melbourne, in September (F. E. Wil- 

 son); Geelong (H. W. Davey). Type, I. 12215. 



One of the few species of the genus with antennae prac- 

 tically identical in the sexes. The pale markings of the elytra 

 consist of a fairly large spot, common to both, at the apex, 

 and a narrow spot on the middle of each side, varying from 

 one-third to one-fifth the length of the elytra; but on one 

 female the lateral spots are absent. The antennae, scutellum, 

 under-surf ace, and legs are less blue than the head and elytra ; 

 they might be regarded as black, with a bluish gloss; on some 

 specimens parts of the elytra have a slight greenish gloss. 

 On each of the nine specimens examined the elytra do not 

 quite cover the abdomen ; on the male the tip of the latter 

 is deeply notched, on the female it is but feebly notched. 



LAIUS JANTH1NIPENNIS, n. Sp. 



cS . Black with a purplish gloss, elytra deep purple, 

 prothorax and parts of basal joints of antennae flavous. 

 With sparse, ashen pubescence, and erect, dark hairs. 



Head with a narrow curved line connecting bases of 

 eyes, front shallowly depressed and subtriangular ; with 

 minute punctures. Antennae with first joint large, its inner 

 apex produced into a truncated lamina, apparent second 

 joint large, its lower-surface gently convex and irregularly 

 four-sided, upper-surface irregularly concave and deeply 

 notched to receive lamina of first joint, the following joints 

 feebly serrated. Prothorax strongly transverse, sides strongly 

 rounded, base gently bilobed, a wide shallow depression near 

 base; sides with fairly numerous punctures, sparse elsewhere. 

 Elytra parallel-sided to near apex, sides and suture thickened ; 

 basal sixth and apical third shining and with sparse punctures, 

 the intervening space subopaque, and with crowded, rugose 

 punctures. Second joint of front tarsi rather large and lop- 

 sided. Length, 3 mm. 



Hab. — Queensland: Roma (Dr. E. W. Ferguson). 

 Type, I. 12216. 



A very distinct species of medium size, and the only one 

 known to me having prothorax entirely pale, and elytra 

 entirely dark. In some respects it is close to the description 

 of L. asperipermds, but is smaller, prothorax immaculate, 

 two joints of each antennae partly pale, and muzzle dark.
