L?:a — Australian Dung Beetles 357 



COPRAECUS HEMISPHAERICUS Guer. 



Plate vi, fig. 5. 



I have not seen the original description of this species, but the figure given 

 in Cuvier's Animal Kingdom(-) slunvs two spines on each of the middle and hind 

 tibiae, although on flgur(> ;]ci only one spine is shown; Ileiche('^) described and 

 figured tlie tibiae as unispinose, find his figure is considerably narrower than that 

 oi' W(^stwo()d"s.( ^) The species is a very rare one, and no locality, other than 

 "Australia," has lieen noted for it; but there are now before me three specimens 

 varying in length from 13 to Ki nun., from East Kiml)erley and Broome. The 

 species may be readily distinguished by the elytra; each of these has six, 

 moderately elevated, shining intei-stices, with a row of setiferous punctures on 

 each side (but the setae api)ear to be easily abraded) ; the middle tibiae are 

 bispinose, the hind ones iniispinose; on the male only there is a curved process at 

 the apex of the hind tibiae. 



The species is probably congeneric with Canthonosoina macleayi, from which 

 the male differs in having the surface less opaque, elytral interstices shining, hind 

 tibiae with an apical hook, and metasternum non-tuberculate. 



TESSERODON VARIOLOSUS Macl. 



Two specimens from Groote Eylandt appear to represent a variety of this 

 species; they are smaller (4-5-4-75 mm.) than usual, and have the elytral inter- 

 stices slightly elevated posteriorly. 



TESSERODON INTRICATUS sp. nov. 



$ Black, antennae palpi and tarsi reddish, clul) flavous. Under-surface 

 and legs rather sparsely clothed, upper-surface with very short setae. 



Head Avith crowded and fairly large asperate punctures. Clypeus with two 

 conspicuous median projections, and two smaller submedian ones, separated by 

 notches. Prothorax more than twice as wide as the median length, front angles 

 produced and rounded, hind ones obtuse; with crowded longitudinal punctures, 

 many of which are confluent. Elytra with sides rounded and evenly continuous 

 with those of prothorax, with narrow geminate striae, interstices wide, elevated 

 and shining in middle, with a row of large but shallow setiferous punctures on 

 each side. Metasternum with large squamose punctures, sparser in middle than 

 on sides. Front tibiae stout and strongly tridentate, hind ones rather thin, with 

 an inner apical hook. Length, 5-5-6 mm.
