INSECTS OF SAMOA. 



the labrum ; in Ananca the tips of the bifid mandibles interlock and scarcely 

 project beyond the labrum. The puncturation of thorax and elytra in Sessinia 

 is usually much finer, and the elytral costae are scarcely indicated. 



Family : CIIDAE. 



Cioidae, Dalla Torre, Coleopt. Cat. (Junk, pars 30), 1911. 



39. Cis savanensis, sp. n. 



oblong, blackish piceous, glabrous ; head with the front margin angularly 

 produced and up-turned above each antennal base ; thorax coarsely and closely 

 punctate, scarcely shining, the front margin strongly rounded but not pro- 

 duced above head, a little flattened in the middle, but not emarginate, lateral 

 margins rather widely expiate and reflexed ; all angles rounded ; elytra shining, 

 with large punctures irregularly distributed, usually appearing more or less 

 hexagonal in shape. 

 Long. 1^ mm. 



Savaii : Safune, rain forest, 2000-4000 ft., 3.V.1924, 2 examples (Bryan). 

 (Paratype in Bishop Museum, Honolulu.) 



Comparable with C. porcatus Shp., of Hawaii, with which it agrees in the 

 shape of the head, but the first joint of the club of the antennae not noticeably 

 smaller than the middle one. The thorax is much more coarsely and closely 

 punctate than in the Hawaiian species, with distinct reflexed lateral margins. 

 The elytra are entirely different ; the punctures are larger than those of the 

 thorax, but much more widely spaced, sometimes almost adjacent one to 

 another, sometimes with comparatively wide intervals ; the punctures deeply 

 set, with interspaces rather strongly convex, giving each puncture a more or 

 less hexagonal appearance. 



40. Cis tutuilensis, sp. n. 



Oblong, brownish testaceous, glabrous ; anterior margin of head lobate 

 and reflexed above each antennal base ; thorax moderately nitid, finely and 

 rather remotely punctate, anterior margin strongly rounded but not produced, 

 emarginate in middle ; lateral margins narrowly but distinctly reflexed.
