138 Mr. D. Sharp on some 



posterius coarctatis, angulis posterioribus rectis, clorso \\.X 

 quadri-impresso ; elytris striatis, striis indistincte crenatis, 

 interstitiis transversim rugosis ; abdomine dense punctate. 

 Long. 4;^ mm.; lat. 1^ mm. 



The sculpture of this species is peculiar and readily 

 distinguishes it ; there are some small and indistinct im- 

 pressions on the elytra. 



The only specimen sent me by Mr. Blackburn was 

 numbered 83, and appears to be a male ; it has a small but 

 quite distinct supplementary segment visible. 



Carpophilus. 



Three species of this genus have been found by Mr, 

 Blackburn. They are all ah'eady described ; two of them, 

 indeed, are amongst the most cosmopolitan of beetles. 

 The third is considered by Mr. Murray as peculiar to the 

 Sandwich Islands, but he appears to have described the 

 species from a unique specimen; and as the specimens 

 sent me by Mr. Blackbiirn of the species show a great 

 deal of variation, I should not be at aU surprised if it be 

 discovered that this third species ( Carpophilus macu- 

 latus, Murray) is not confined to the Hawaiian group of 

 islands. 



1. Dermestes hemipterus , Lin. 



Mr. Blackburn states that this species is very rare in 

 the islands; indeed he has found only three individuals 

 of it, two of them in a retired valley of the Island of Maui, 

 and the third in Oahu, on fallen fruit. 



2. Carpophilus dimidiatus, Er. 



This insect Mr. Blackburn says is almost the com- 

 monest Hawaiian beetle. 



3. Carpophilus maculatus, Murray. 



This species is also common, and has been found by 

 Mr. Blackburn both in Maui and Oahu. I am inclined 

 to think, from Avhat I recollect of the series in the British 

 Museum, of the very variable Carpophilus vittiger, Murray, 

 that this species will prove to be extremely closely allied 

 to it ; the C. vittiger is widely distributed in the Malay 

 Archipelago and India.
