appearance the species is close to sparsus, but is even more 

 parallel-sided, femoral dentition much smaller (on one speci- 

 men from Port Lincoln it is practically absent) and terminal 

 joint of antennae (both sexes) much longer; fill for mis has 

 very similar outlines, but the clothing and antennae are 

 different; difficilis is also close, but has a shorter rostrum, 

 antennae with apical joint much shorter, etc. ; structurally 

 it is fairly close to pudicus, but is very differently clothed. 

 The dentate specimens in my table would be associated with 

 brunneus, with which they have few details in common; the 

 edentate ones with edentulus, angustulus, and inconstans, 

 from which they differ in the sutural clothing and in the 

 antennae. The elytral suture to the naked eye appears to be 

 narrowly and almost uniformly clothed with whitish 

 pubescence, but under a lens thi6 is seen to consist of numerous 

 more or less loosely conjoined spots, somewhat more widely 

 distributed near the base than elsewhere (on an occasional 

 specimen, however, the maculate appearance is less evident). 

 As on many other species of the genus the elytra have some 

 dark pubescence (fairly conspicuous on the outer apical 

 margins), but it is very short and indistinct. There are 

 numerous conspicuous granules on the sparsely clothed parts 

 of the under-surface. 



Belus halmaturinus, n. sp. 



Blackish; elytra, rostrum, antennae, and legs of a rather 

 bright red. Moderately clothed with whitish and stramineous 

 pubescence. 



Head densely granulate-punctate between eyes, punctate 

 about base. Rostrum moderately long, rather thin and iightly 

 cuived ; behind antennae with punctures much as on base of 

 head, in front shining and with small to minute punctures. 

 Antennae inserted about one-third from base of rostrum, first 

 joint almost as long as second and third combined, second 

 thicker and just perceptibly longer than third, the latter 

 slightly longer than fourth, fourth-tenth subequal in length, 

 but after the sixth distinctly increasing in width, eleventh 

 about once and one-half the length of tenth. Prothorax 

 lightly transverse, sides rather strongly rounded, base very 

 little wider than apex, median line not very deeply impressed ; 

 densely granulate-punctate. Elytra thin, not much wider 

 than widest part of prothorax, parallel-sided to near apex, 

 which is lightly produced, suture -not elevated at base; with 

 dense punctures, about base with a few granules. Femora 

 edentate, hind pair extending to about middle of second 

 abdominal segment; basal joint of tarsi much shorter than 

 second and third combined. Length, 7-74 mm.
