COLEOPTERA 255 



Cis Latr. 



(i) Cis alienus Sharp. 



Cis alienus Sharp, Tr. Ent. Soc. London, 1879, p. 91. 



This is very different to any other Hawaiian species, and is probably either a 

 natural immigrant, or has been introduced by man. Its general appearance, the 

 clothing of the under parts, the great length of the prosternum in front of the coxae &c., 

 are all foreign to the true native type. 



Hab. Oahu, Honolulu, mountains ; two examples taken (Blackburn) ; Waianae 

 mountains, several examples, Perkins. It is probably a scarce insect. 



(2) Cis pacijictts Sharp. 



Cis pacificiis Sharp, Tr. Ent. Soc. London, 1879, p. 91. 



The most common-place species of the genus as represented in the islands, and 

 probably not truly indigenous. The processes on the head of the ^ vary greatly 

 in development. 



Hab. Throughout the islands in the mountain forests. 



(3) Cis breviformis, sp. nov. 



Parum elongatus, ferrugineus, pronoto plus minusve infuscato, pedibus antennis- 

 que rufo-testaceis, harum articulis apicalibus nigricantibus. Pronotum opacum vel 

 minus nitidum, brevissime griseo-pubescens, sat latum, densius subtiliter punctatum. 

 Elytra breviuscula, griseo-pubescentia, haud maculata, parum profunde ruguloso- 

 punctata. Long. 2 mm. 



Somewhat like Cis pacificus in form, and quite unlike any other Hawaiian species. 

 The thoracic puncturation is rather close and very fine, that of the elytra is larger, but 

 shallow, rugose and irregular. Both the thorax and elytra are clothed with very short 

 pale setae, which hardly stand out from the surface, but are quite conspicuous, and with 

 the short form and ferruginous colour give the species a very distinctive appearance. 



Hab. Molokai. Two examples taken at an elevation of above 4000 ft.
