in the clothing of its pronotum; the mentum is intermediate 

 in prominence between that of dives and aurilegulus . The 

 antennae are of normal form for the genus, but the hind tibiae 

 are unsually short and wide. The clothing of the lateral 

 gutters of the pronotum is as in Blackburn's Group 2, of 

 Haplonycha (ante, 1906, p. 292), whilst the apical joint of 

 the maxillary palpi is as in his Group 3 ; in fact there is quite 

 a strong resemblance of this species to H. mauricei, originally 

 described from Ooldea; the resemblance, of course, is only 

 superficial, as the antennae, mouth parts, and legs, etc., are 

 all very different. 



Aneurystypus pilosicollis, n. sp. 



d . Bright-castaneous, some parts darker. Under- 

 surface, legs, and pygidium with dense, long, stramineous 

 hair, elytra (except for the marginal fringes and for a few 

 hairs at base) glabrous, rest of upper-surface moderately 

 clothed. 



Head coarsely and irregularly sculptured between eyes, 

 but becoming smooth towards base; clypeus with front and 

 sides rounded and strongly elevated, the latter abruptly 

 truncated at base, suture deep, punctures rather small and 

 irregular. Antennae ten-, club three-jointed, rami rather thin 

 but as long as head is wide. Prothorax more than twice as 

 wide as long, sides rather strongly rounded, angles rounded 

 off, front neither excavated nor tuberculate ; punctures 

 moderately large and unevenly distributed. Elytra slightly 

 wider than prothorax ; punctures and striae much as on 

 preceding species. Pygidium and legs much as on that species. 

 Length, 9-10 mm.

The clothed and unarmed pronotum, densely clothed 

 pygidium, and very short hind tibiae, readily distinguish 

 this from all previously described species, except the preceding, 

 from which it differs in being smaller, sculpture of the head 

 more irregular, mentum much more prominent, prothorax 

 with coarser punctures and its clothing not confined to the 

 gutters, but scattered about on the disc as well; the mentum 

 is very prominent, in this respect being second only to that of 

 pauxilhis. The three specimens before me all have the basal 

 half of the head almost black, and they all have the suture 

 and outer apical parts of the elytra infuscated; two have the 

 scutellum darker than the adjacent parts of elytra, and one 

 of these has the prothorax rather deeply infuscated. On the 

 head between the eyes the clothing is shorter and sparser than 

 on the pronotum.
