266 FAUNA HAWAIIENSIS 



(2) Apterocis vagepunctatus Blackb. 



Cis vagepundatiis Blackburn, loc. cit. p. 166. 



Hab. Oahu. A single specimen in the mountains near Honolulu (Blackburn) ; I 

 have not met with this species.

(3) Aptej'ocis lanaiensis, sp. nov. 



Nigricans, pronoto nonnunquam plus minusve piceo vel rufescente, elytrorum apice 

 humerisque rufo-maculatis, antennarum basi pedibusque rufescentibus. Nitidus, valde 

 aequaliter convexus, pronoto ruguloso-punctato, postice baud evidenter marginato. 

 Elytra circa basim sparsim vage punctata. Abdominis segmenta ventralia evidenter 

 densius punctata. Long, circa 2 mm. (Plate X. fig. 14.) 



A very distinct species by the rugulosely punctured prothorax, vague scattered 

 punctures at the base of the elytra and the distinct humeral and apical red spots on the 

 latter. The general form of the insect is like that of Cis cphistemoides. 



Hab. Lanai. Three examples were taken on the summit of the mountains. 



(4) Apterocis montamts, sp. nov. 



Brunneus, valde aequaliter convexus, capite pronotoque nigricantibus, hoc antice 

 posticeque pallido-marginato, antennis testaceis. Pronotum remote subtiliter sub- 

 obsolete punctatum, postice levissime marginatum. Elytra basim versus obsoletissime 

 punctata, vage subrugulosa, setulis brevissimis pallidis, vi.x videndis, ferentia. Ab- 

 dominis segmenta ventralia necnon metasternum nitida et impunctata. Long, circa 

 2"2 mm. 



Apterocis nioiitanus var. minor, var. nov. 



Minor, pronoto fere impunctato, elytris plaga vaga transversa obscuriore. Long, 

 circa 1*5 mm. 



Much smaller than the typical specimens, but obtained in company with these. 

 They differ in the nearly or quite impunctate prothorax, and the elytra have the base 

 and apex paler than the middle portion, giving them a vague banded appearance. I 

 can detect both sexes in these small examples and it is possible that they are really a 

 distinct species. 



Two or three examples from Molokai appear to belong to this species and in some 

 respects unite the typical examples with the var. minor by the following characters :
