COLYDIIDAE. 



Philothermus Aube. 



Phil other mus crihricollis, n. sp. 



Oblong, shining-, nigro-piceous above, piceoiis beueatli, the head, pnlpi, 

 antennae, and legs ferruginous. Head somewhat closely, conspicuously punc- 

 tate ; antennae about reaching the base of the prothorax, 11-jointed, the club 

 freely 2-jointed, 10 strongly transverse, joint 9 also transverse and considerably 

 wider than 8. Prothorax convex, much broader than long, feebly rounded at 

 the sides, gradually narrowing from a little before the base to the apex, the 

 anterior angles prominent, the reflexed lateral margins narrow, the basal foveae 

 deep ; very coarsely, closely punctate. Elytra moderately long, slightly rounded 

 at the sides, and at the middle wider than the prothorax, the margins without 

 projecting carina, the humeri angulate ; with rows of coarse subapproximate 

 punctures placed in shallow striae, the interstices almost flat, sparsely puuctu- 

 late. Beneath sparsely, the presternum and the sides of the metasternuni 

 coarsely, punctured ; metasternuni sulcate down the middle. 



Length 2^-3 mm. 



Hah. Chile, Cliiloe Island (C Darwin). 



Four specimens, numbered 2369 in Darwin's register. This species 

 is larger and has a more coarsely punctate protliorax than any of the 

 described members of the genus known to me. The antennae have a 

 freely articulated 2-jointed club, as in P. depressus Sharp, from Japan, 

 P. cerylonoides Reitt., from Brazil, etc. In the allied genus Cerylon, 

 the antennae are 10-jointed and the club solid. The enlarged ninth 

 antennal joint in P. crihricollis might, perhaps, be counted as belonging 

 to the club. 



Bteehidae. 



MoETCHASTES Fairm. 

 Morychastes australis Blanch. 

 Hal. TiEREA. DEL FuEGO, Orange Baj^ Perrier Isl. ; Straits of 

 Magellax, Port Famine. 



Two examples found by Darwin agree with Enderlein's figure of 

 j\L australisj that of Blanchard being unsatisfactory. They are labelled 

 " Bahia," possibly in error, the handwriting being different from that 

 attached to the specimens mounted at an earlier date. 



Parxidae. 



Elmis Latr. 



EJmis chiloensis, n. sp. 



Oval, very shining, black above, piceous beneath, the antennae, anterior 

 margin of prothorax, and legs rufo-testaceous. Antennae very slender. Pro- 

 thorax transversely convex, a little broader than long, feebly rounded at the
