5o6 FAUNA HAWAIIENSIS 



(i) Cillaeopeplus infimus, Sharp. . 



Brachypeplus infimus Sharp, Tr. ent. Soc. London, 1878, p. 135. 



" Omnium perdepressus, elongatus parallelus subopacus, sine pubescentia, fuscus 

 vel fijsco-testaceus, pedibus dilutioribus ; ocuhs vix ad capitis ans^ulos posteriores rectos 

 attingentibus, haud magnis ; prothorace transversim oblongo, crebre subobsolete 

 punctato; elytris profundius striatis, interstitiis seriatim sed vix perspicue punctatis ; 

 abdomine subtilissime punctulato. Long. 3^ — 4^^ mm. ; lat. I mm." 



Plate XIV. fig. 5, ¥. 



We have six specimens of this species found by Mr Perkins on Oahu, and he also 

 found a good series of 30 specimens on Lanai, and I am not able to distinguish these 

 specimens from those sent me by Mr Blackburn as coming from Oahu. 



Hab. Oahu, Lanai. — Oahu; "under the bark of trees on the mountains" 

 (Blackburn); Konahuanui Ridge, and mountains near Honolulu (Perkins). — Lanai; 

 2000 ft. and over, xii. 1893 '^'''d i- 1894 (Perkins). D. S. 



(2) Ci/laeopeplus perkinsi, sp. no v. 



Elongatus, parallelus, depressus, haud nitidus; prothorace subtiliter rugoso-punctato; 

 elytris profunde punctato-striatis ; femoribus posterioribus margine postico medio angulo 

 acute prominulo. Long. 4 — 5, lat. i^ mm. 



We have only a short series of eight examples of this species, but there is no doubt 

 of its distinctness : indeed the angular prominence on the hind femora distinguishes 

 C. perkinsi from all the other Hawaiian Nitidulidae. The striation of the elytra is very 

 deep and regular. Our series includes both sexes; there is but little difference between 

 them, except that the male has a small convex supplementary segment as in C. infimus. 



Hab. Kauai; all from Makaweli, 2500 ft. 11. 1897 (no. 703, Perkins). D. S. 



(3) Cillaeopeplus dubius, sp. nov. 



C. infinii peraffinis ; paulo robustior, minus subtiliter sculpturato, elytris striis 

 latioribus et profundioribus. Long. 3^^ mm. 



A single specimen, of the male sex, found on Hawaii does not quite accord with 

 C. infimus, and I think will prove to be another species rather than a variety. It is 

 shining, the thorax is a little narrower in comparison with the length, it is distinctly 

 punctate at the sides, and the peculiar dull patch on the middle contrasts strongly with 

 the sides. The striae on the elytra are so broad and deep that they are grooves, almost 

 broader than the interstices. 



Hab. Hawaii, Kilauea, vii. (895 (no. 691, Perkins). D. S.
