tarsi more or less reddish. Clothed with stout, white, 

 depressed hair or setae, longer and denser on the under- 

 surface than on the upper, where it is almost evenly 

 distributed, except that on the elytra it has a subgeminate 

 appearance, and that there are some longer fringing hairs; 

 hind parts with dense subsquamose clothing. 



Head coarsely granulate-punctate; sides of clypeus 

 oblique, front acutely tridentate. Antennae apparently eight-, 

 club three- jointed. Prothorax granulate-punctate, the 

 punctures of moderate size and not very close together. Elytra 

 with irregular rows of punctures, a small granule behind 

 each; a transverse, shining, interrupted space across summit 

 of apical slope. Hind parts with dense but more or 

 less concealed punctures. Front tibiae with a strong and 

 acute apical tooth, a smaller submedian one, and a very small 

 one near base ; basal joint of hind tarsi scarcely half the 

 length of second. Length, 4J-4J mm. 



Hob. — Western Australia: Ankertell (H. W. Brown). 

 Type, I. 4584. 



A shining species that in Blackburn's table would be 

 associated with pygmaeus, from which it differs in its con- 

 spicuously tridentate clypeus; opaculus has the clypeus 

 tridentate, but less acutely than on the present species, its 

 prothorax is very differently sculptured, clothing of hind parts 

 sparser and considerably finer, and feminine brands much 

 more conspicuous. The clothing of the hind parts is almost 

 squamose in character, on the upper-surface the setae are 

 thinner but still fairly stout. Of the four specimens before 

 me three are apparently females, and of these two have a 

 vague greenish gloss on the pronotum, the third has the 

 elytra with the margins (as well as the base and suture) 

 infuscated; the fourth specimen is apparently a male (in 

 Automolus the female is the more distinctive sex of the 

 species), and has the elytra and antennae entirely black, the 

 upper-surface much less shining, with thinner and denser 

 (although not longer) and mostly black or blackish clothing, 

 the pygidium with finer clothing (scarcely even setae) and 

 the clothing on the under-surface rather thinner and less 

 dense. 



Automolus propygidialis, n. sp. 

 PI. xxxvii., fig. 147. 



Black; elytra, legs, antennae (club excepted), and palpi 

 more or less castaneous, abdomen darker, with moderately 

 .long, pale, and rather dense clothing, shorter on hind parts, 

 and darker on middle of pronotum than elsewhere. 



Head with dense asperate punctures; clypeus with sides 

 oblique and lightly incurved, apex truncate. Antennae
