COLEOPTERA 263 



A very remarkable species of the same curious form as C. haleakalae, and no doubt 

 either wingless or with only rudimentary wings, though it has not been examined in 

 this respect. The coarse rugose sculpture of the elytra, amongst which distinct 

 puncturation is evident, distinguish it at once. 



Hab. Kauai, 4000 ft. One example captured. 



(23) Cis fallax, sp. no v. 



Testaceus, pronoto saepe medio nigricante vel fusco, elytris nigro-maculatis, 

 C. signato colore similis, et eodem vestitu et puncturatione, sed forma magis convexa, 

 elytrorum lateribus magis rotundatis, alls brevioribus, ad apices elytrorum baud extensis, 

 distinguendus. Long. i'5 — vix 2 mm. 



I have found it necessary to separate a few examples taken in company with 

 C. signatus from that species, although they do not differ from certain of its varieties 

 either in colour, clothing or sculpture. They are decidedly more convex than C. signatus 

 and the sides of the elytra are more rounded, so that they often appear rather shorter 

 and more pointed at the apex. On dissecting one of these specimens we find the wings 

 to be less developed than those of the preceding species, and in repose they do not 

 nearly reach to the apex of the abdomen, as is the case in the numerous examples 

 of C. signatus that we have examined. For these reasons it is advisable for the present 

 to consider the two forms as distinct species. 



Hab. Oahu. Three or four examples have been taken in the Waianae mountains 

 in company with C. signatus. 



(24) Cis miiJius, sp. nov. 



Nigricans, pedibus, antennarum basi, pronoti margine antico et postico (vel horum 

 altero), elytrisque testaceis, his nigro-signatis ; colore variabilis, nonnunquam totus 

 testaceus, elytris nigro-notatis ; C. signato vestitu et colore simulans, setulis brevis- 

 simis crebre ubique vestitus. Pronotum densissime punctulatum. Elytra subinae- 

 qualia, basim versus grossius rugoso-punctata. Long, i '5 — 2 mm. 



Like many specimens of C. signatus in colour and setulosity, but easily distinguished 

 by the coarse but shallow punctures on the elytra, the surface of which is somewhat 

 rugose and uneven, and the insect is more convex. The wings are apparently not 

 fully developed as compared with the ordinary condition of these organs in the genus, 

 but we have not been able to fully examine the species with regard to this point. There 

 are normally four black spots on the dorsum of the elytra, which may be connected 

 more or less laterally. 



Hab. Maui, Haleakala (5000 ft.) ; three examples taken.
