10 Descriptive Catalogue [1897. 



with the present species, but this I have not been able to ascertain. 

 I had imagined that C. concolor, owing to the shorter antennae 

 and their straighter shape, was the female of C. Smithi, of which 

 MacLeay has given an excellent figm-e, but on dissection I have 

 found that these specific characters hold good in both sexes. Length 

 11^14 mm. ; width 5-6 mm.

Cerapterus laceratus, Dohrn, 

 Stett. Ent. Zeit., 1891, p. 388. 



" Not very well preserved, but yet so far recognisable that it can 

 be plainly described, is another Paussid, the habitat of which, nearer 

 than South Africa, I am not aware of. The half of the right posterior 

 elytron and several tarsi are wanting. However, as I have waited 

 eight years in vain for a second specimen, I describe mine as follows : 

 Paussus [Cerapterus) laceratus; brownish red; elytra moderately 

 shining and having a fulvous lunule towards the apex ; eyes black ; 

 prothorax shining ; elytra slightly wider than the prothorax and 

 elongate. Length 15 mm. ; width 4 mm. 



" Through the shape of the well-preserved antennge the animal is 

 connected with C. Smithi, Lafertei ; this confirms its African origin. 

 It differs from these two species in having a somewhat more slender 

 facies ; the fulvous lunule at the end of the elytra, as well as the 

 characteristic antennae and tarsi, show the animal to be unmistakably 

 a Cerapterus. The species of that genus in my collection [C. Smithi, 

 concolor, Lafertei) are all dark brown, nearly black, but C. laceratus 

 is light reddish brown ; this and a somewhat narrower prothorax 

 give it a more slender appearance. I have no doubt that it is 

 specifically different."

 Smith's Illustr. Afric. Annul., 1838, p. 75. 



Head and antennte as in Cerapterus ; maxillae without outer lobe, 

 not hooked at tip but with six sharp teeth along the iimer edge ; 

 ligula very small, triangular ; legs compressed, anterior tarsi of 

 male not much dilated, papillose underneath, posterior and inter- 

 mediate slightly less papillose underneath and more villose laterally, 

 those of the female ciliate underneath ; prothorax somewhat cordi- 

 form ; head with two round depressions on the vertex. 



This genus has several representatives in Australia, and another 

 species is recorded from Abyssinia.
