of legs dark, the antennae of its female, however, are very 

 .similar. In appearance it is closest to H. latus, but is 

 somewhat narrower, antennae longer and more strongly 

 serrated in male, the terminal joint not constricted in middle, 

 and more of the legs and less of the head pale. 



Laius sinus, Lea. 

 A specimen, from Gosford, the locality of the type, is evi- 

 dently a female of this species, its apparent second joint 

 (really the third) of antennae is much larger than is usual in 

 females (but in this it resembles the female of L. flavono- 

 tatus) but much smaller than in the male and simple, from 

 the male also it differs in having the following joint reddish, 

 less of the muzzle reddish, the head with very small punctures, 

 and the front tarsi and abdomen simple. 



Laius flavifrons, Lea. 



Two males, from Parachilna (South Australia), differ 

 from the type in having two narrow dark lines extended in 

 front from the dark interocular space, parts of the under- 

 surface of the two basal joints of antennae (in error in the 

 original description ( 13 ^ the second joint was referred to as the 

 "basal" one) and the legs entirely dark; the dark subapical 

 markings of the elytra are also connected across the suture. 

 One of the specimens has a black blotch, with a greenish 

 gloss, occupying rather more than the median third of the 

 prot-horax, touching its base but not apex ; this specimen 

 at first glance somewhat resembles L. nidicola, L. inter- 

 medins, and L. villosus, all of which have much larger punc- 

 tures on the elytra, and very different antennae. 



Laius pallidus, Lea. 

 A male, from Parachilna, with antennae identical with 

 those of the type, has the dark part of the elytra not in the 

 form of sharply limited spots, but more like a deep stain, 

 irregularly occupying most of the basal two-thirds, with a 

 whitish spot, completely isolated at the basal third, on each 

 elytron : its scutellum is black. 



Laius verticalis, W. S. Macl. 

 A male of this species, from Wyndham (North-western 

 Australia), is somewhat smaller than the females before me; 

 the basal joint of its antennae is large, and with a process 

 obliquely placed, so that from some directions the process 

 itself appears narrow, parallel, and elevated at right angles 

 from the mass of the joint, from other directions it appears
