58 Mr. F. P. Pascoe on new Genera and 



form a neck, would seem to indicate a different type. 

 Ixalmaj another anomalous genus, with somewhat similar 

 legs, but having a free pygidium, I refer to the neighbourhood 

 of Tachygoniis. M. lioelofs (Ann. Soc. Ent. Belg. xvii. 

 p. 126) places his genus Celia^ ^ apparently identical with 

 Ixoilma.j among the ^' Eugnomides," /. e. with the Erirhininse. 

 These are all isolated forms ; but I think the pygidium offers 

 a more important character than the separation or the conti- 

 guity of the anterior coxoj. The species described below 

 differs considerably in coloration, some individuals being of an 

 almost uniform dark brown, others pale brown on the disk of 

 the elytra ; some have the elytron prettily variegated — a cen- 

 tral dark triangular spot with a light semicircular line behind, 

 and other variations. 



Pactola variahilis. 



P. obloiiga, fusco- vel brunneo-sqiiamosa, aliqaando variogata ; an- 

 tennis fulvis, apicem versus iufuscatis ; prothorace subcylindrico, 

 in medio bituberculato ; elytris basi prothorace fere triple latio- 

 ribus, supra tuberculatis, antioe subdepressis, late striato-punc- 

 tatis ; corpore infra sparse punctato. Long. 1-| lin.

Idotasia egena. 



I. elliptica, nitide nigra ; rostro pone basin fortiter arcuato, dimidio 

 basali antice punctis magnis oblongis approximatis impresso ; 

 oculis grosse granulatis ; antennis fulvo-ferrugineis ; clava ob- 

 longo-ovata ; prothorace sat vage punctato ; elytris vage leviter 

 punctulatis ; pedibus piceis. Long. 1| lin.

This species is more nearly allied to the Batchian /. scajjhi- 

 aides than to either of the Australian members of the genus ; 

 it is, however, broader and less convex, the posterior portion 

 of the elytra less attenuated, the intervals of the punctures on 

 the rostrum less decidedly elevated or cariniform, &c. Idotasia 

 now contains nine species — five from New Guinea and the 

 neighbouring islands, two from Queensland, one from New 

 Caledonia, and the above. They are very homogeneous, ex- 

 cept the one from New Caledonia, but are differentiated by 

 well-marked characters. 



Arceocervs pardalis. 



A. dense pubeseens, fuscus, albido maculatus ; antennis breviuscuHs, 

 nitide fulvis, articulis tertio ad quartum paulo elongatis ; clava 



* Celia lias long been used for a genus of Cavabidte.
