Coleopterous Family Bostrichidas. 349 



pubescence) it is difficult to see. His type has, however, six 

 joints to the funiculus. 



This species appears to be found all over the world. Speci- 

 mens are in the British Museum from the following- locali- 

 ties : — St. Helena, Madeira, Sierra Leone, Bangalore, 

 Ceylon, Penang-, Siam, Hong Kong, Java, Celebes, New 

 Guinea, Dorey, Philippine Islands, Brazil, Santarem. 



The specimen from Madeira is the type of Rhizopertha bi- 

 foveolata, Wollaston, so named on account of the two approxi- 

 mate fovea at the base of the thorax which are so charac- 

 teristic of the species. I think there can be no doubt that it 

 is Ajjate minutaj Fabr., from New Zealand, but most unfor- 

 tunately the type is no longer to be found in the Banksian 

 collection *. From Dr. Horn's description of D. brevis (Proc. 

 Amer. Phil. Soc. 1877, xvii. p. 550} it is evident that it ia 

 closely allied to tm'nuta^ and may even be the same species. 



Xylopertha, Gu^rin, 1845. 



Guerin (Bull. Soc. Ent. Fr. 1845, p. xvii) mentions four 

 types for this genus : — Apate minuta, F., triincata, Dej., 

 longicoi'nis^ F., and sinuata^ F. As minuta, according to the 

 foregoing note, is Dinoderus, Steph., and longicomis has now 

 the genus Tetrap>riocera^ Horn, for its reception, it would be 

 best, in my opinion, to retain the name Xijlojpertha for truncata 

 and sinuata &c. 



Apate substriata^ Payk. 



I propose the generic name Steplianopachys for this species, 

 which is too well known to require description, being the 

 Dinoderus of many authors, but not of Stephens. 



Rhizopertha rufa^ Hope. 



I think it very doubtful whether this species should be 

 separated from i?. pusilla. Typical examples, however, in 

 the British Museum collection are not in sufficiently good 

 condition to enable me to say positively. 



It may be useful to point out that Bostrichus rnutilatus, 

 Walker, is a Xylopertha and must be transferred from under 

 Tomicus in Gemminger and Harold's Catalogue, p. 2691. 



* I have just received a letter from M. Fleutiaux of Paris (who sent 

 me a specimen under the name of minuta, F., to compare with the type), 

 in which he informs me that it is Rhizopertha sicula, Baudi, and Xylo- 

 pertha fovekollis, Allard.
