Coleoptera of the Falkland Islands. 183 



The seventeen specimens of this insect before me, including 

 several males, exhibit considerable variation in the elytral 

 markings: three only ( cT c? ) have an interrupted sub- 

 riiarginal stripe of pallid scales (a character used by 

 Enderlein in his table of the species) ; others have small 

 scattered patches of pallid scales along the rows of punctures ; 

 others, dirtier, have the vestiture uniformly dark brown. 

 The oblique dilatation of the* elytral humeri is more pro- 

 nounced in the $ than in the ? . The penis-sheath is broad 

 and acuminate, and the first ventral segment transversely 

 hollowed anteriorly, in $ . The eight examples received by 

 the Museum from Mr. Havers in 1873 were captured in 

 18G0. A specimen (<£) in the same collection, from that of 

 Bowring, is labelled "Am. bor. Dnpont," obviously in error, 

 as the insect is precisely like those from the Falklands. 



38. Reichertia insquamea, Enderlein. 



Hob. Falklands, Fox Bar. 



Described from two specimens found in March 1902. 

 These seem to be partially abraded females of R. exsciilpti- 



collis, the sexes of which were not identified by Enderlein. 



39. Reichertia scabra, Enderlein. 



Hob. Falklands (Th. Havers, Col. A. M. Beid, C. J. C. 

 Pool), Port Stanley (Enderlein, M. Cameron), Port Darwin, 

 Seal Cove (Enderlein) . 



About a dozen examples before me seem to belong to this 

 species. They are considerably smaller than R. exsculpti- 

 collis (length 4^-6i mm., exclusive of head), and have the 

 anterior margin of the prothorax a little straighter, and the 

 oblique humeral dilatation of the elytra less prominent, at 

 least in <$ . Clean specimens show numerous small sub- 

 quadrate patches of pallid scales on the elytra, giving a 

 mottled appearance to their surface. The tuberculiform 

 elevations towards the apex tend to become longidudinally 

 confluent in most of them. Enderlein's figure is unsatis- 

 factory, if the insect has been correctly identified by me. 



40. Falklandius brachyomma i Enderlein. 



Hub. Falklands, Port Stanley (Enderlein, M. Cameron). 



Described from two examples captured in 1902. Seven 



males and two females were taken by Mr. Cameron at the
