258 FAUNA HAWAIIENSIS 



(9) Cis unicus, sp. nov. 



Testaceus, nitidus, haud setosus, capite infuscato, elytris in parte basali lateraliter 

 nigro-fuscis. Pronotum nitidum, subtilius vix dense punctatum. Elytra nitida, grossius 

 irregulariter ruguloso-punctata. Long. 2 mm. 



Closely allied to C. nigrofasciatus, but smaller than the smallest example of that 

 species, and decidedly more shining. The puncturation of the elytra is coarse but 

 shallow, somewhat rugose and irregular, the punctures appearing to differ in size. The 

 colour of the elytra is testaceous, but the basal half is to a large extent blackish or 

 infuscate, except along the suture, and the dark colour at a point rather beyond the 

 middle of the length of the wing-cases extends inwards nearly to the suture, to form a 

 vague interrupted band. I can detect no trace of setae either on the thorax or the 

 elytra. 



Hab. Hawaii. A single example was taken at Kilauea. 



(10) Cis porcatus Sharp. 



Cis porcatus Sharp, Tr. Ent. Soc. London, 1S79, p. 92. 



This minute species is easily recognized by its dark colour, very dense sculpture 

 and short grey clothing, which however is easily abraded. The head of the cT is pro- 

 duced into strong angular processes, which vary greatly in development. 



Hab. One of the commonest of the island species and of general distribution in 

 the forests from 1 500 to 4000 ft. 



(11) Cis instilaris Sharp. 



Cis insiilaris Sharp, Tr. Dublin Soc. 1885, p. 164. 



(Plate X. fig. 19.) 



A unicolorous, or nearly unlcolorous, testaceous species, with strong and very 

 dense puncturation over the whole surface, the elytra and also the prothorax in 

 fresh examples bearing excessively short setae. The thorax and base of elytra are 

 sometimes infuscate, and in some the elytra are quite pallid, but there are no distinct 

 markings. The c/ has the front of the head produced into two processes, which, as 

 usual, vary greatly in development. Length 2 — 27 mm. 



Hab. Kauai, Oahu, Lanai, and Hawaii. Taken on most of the islands rather 

 sparingly, and it no doubt occurs on all. It is found in the forests from 2000 — 4000 ft. 

 About a score of examples were captured.
