210 Mr. D. Sharp on some Longicorn Coleoptera. 



tion, become sparing and obsolete, the clothing consists of 

 a somewhat mottled or patchy clay-coloured tomentum, 

 more or less mixed Avith small white or grey patches, 

 which, however, may be quite overlooked unless a careful 

 examination is made ; the pale and somewhat obscure 

 transverse band on the elytra is placed just behind the 

 middle, and consists of an obHque fascia on each, the 

 sutural portion being rather nearer to the front than the 

 marginal portion. The male seems to differ from the 

 female only by a rather greater development of the legs 

 and antennas. 



Three specimens of this species have been sent by INIr. 

 Blackburn as No. 90 ; it is occasionally found by him in 

 his house at Honolulu, and he considers it is probably 

 attracted by light. 



Oopsis, Munich Cat. 



Lamia nutator. Fab. This species shows a well-marked 

 sexual variation in colour, the pubescence in the female 

 being clay colour, while in the male it is neai'ly Avhite ; 

 the general colour of the surface in the female is more or 

 less distinctly ferruginous, while in the male it is nearly 

 black ; in this latter sex the legs and tarsi are stouter 

 than in the female. 



This is one of the commoner insects in Oahu ; it is the 

 No. 22 of Mr. Blackburn's parcels. Fairmaire has de- 

 scribed three other species from Tahiti, bvit has given no 

 differential characters, and it may perhaps prove that they 

 are not sufficiently distinct from the common Fabrician 

 species, which is reputed to occur also in Australia. 



LAGOCnmus, Munich Cat. 



Ceramhyx araneiformis, Lin. I have received three 

 individuals as No. 89 from Mr. Blackburn, which must 

 be referred to this species, although they are of very small 

 size (13 to 17-J- mm. long.), and the dilatation and clothing 

 of the male anterior tarsi and tibias is but little different 

 from what exists in the female. This species is in tropical 

 America one of the commonest and most widely-distri- 

 buted Longicorns ; it has been recorded by Fairmaire as 

 occurring in Tahiti, without any remark as to a diminu- 

 tion in its size there.
