BY A. RAFFRAY. 



Genus Abascantus, Schaufuss. 



1233 



Tijds. v. Ent. xxix. p. 25S. 



I shall only mention this genus, referring the student to Dr. 

 Schaufuss's description, and the complementary observations I 

 gave in the Rev. d'Ent. (1S90, p. 148, tab. iii. figs. 15, 15'). It 

 . is closely allied to Tyromorphus, Raffr., but the last joint of the 

 maxillary palpi is comparatively much larger and strongly 

 truncate at apex; this truncate part is carinate all round with 

 the internal angle sticking out and has also a longitudinal carina 

 on the upper surface, the third joint is irregularly ovate and 

 much smaller than the last one; the first dorsal segment is also 

 much larger than the others. 



It includes only one species, A. sanuio, Schfs., (loc. cit.) and 

 Raffray, Rev. d'Ent. (1890, PI. iii. figs. 15, 15'). 



King George's Sound, W.A. 



Genus Duebos, Sharp. 



Trans. Ent. Soc. Lond. 1874, iv. p. 495. 



This genus has been characterised in a masterly manner by 

 Dr. D. Sharp. It comes close to Gerallus and Schavjussia, and 

 agrees with the latter in having the eyes situated near the 

 posterior angles of the head; the maxillary palpi are also long, 

 the joints being slender at the base and clavate at apex, the three 

 last ones do not differ much in size, the 4th has also a small 

 clivage at apex. It differs from Schaufussia by the antennal 

 tubercle, which is as broad as the head, and the latter is not 

 angularly constricted in front; the elytra are very short. Roth 

 Durbos and Schaufussia differ from Gerallus by the position of 

 the eyes, which are in the median part in Gerallus; and by the 

 large size of the first dorsal segment. 



This genus includes only two species, priscus, Sharp, (loc. cit.) 

 from Champion Bay, W.A., and interruptus, Schfs., (Tijds. v. 

 Ent. xxix, p. 291) from Sydney. I received the latter of these 

 from Mr. Masters under the name of Rhytus punctatus, King.
