156 FAUNA HAWAIIENSIS 



Hab. Maui, Haleakala, 5000 ft. (October). — Lanai, 2000 ft. (June) ; Halepaakai 

 (July). — Molokai (July). — Oahu, Waialua, Koolau range, 2000 ft. (April). — Kauai, 

 4000 ft. (July, August). I have seen 14 examples of this somewhat variable species. 



The elytra are sometimes pale cinereous, pronotum posteriorly much marked with 

 brown. Whole under surface dark brown. Legs darker and femora distinctly annulate 

 with black and brown. 



(5) Reduviolus shai'pianus, sp. nov. 



Plate V. fig. 36. 



Tylus, base of head, pronotum, apical third of elytra, scutellum, genital segments, 

 abdomen beneath etc. sanguineous. Head, lateral margin of pronotum, central line 

 along scutellum, abdomen above, sterna (in part) black. Antennae, rostrum, and legs 

 pallid (more or less sanguineous) flavous, apex of femora and base of tibiae sanguineous, 

 apex of tibiae and of each tarsal segment blackish. Connexivum sanguineous spotted 

 with black. Membrane cinereohyaline ; nervures pale lilac-brownish. In structure and 

 size similar to R. ruhritinctus (and also often in colour and pattern), distinguished by 

 the slender basal segment of antennae. 



Hab. Kauai, High Plateau (August), 4000 ft. (July). I have seen five examples. 



(6) Redmno/us siihni/ns, White.

I have unfortunately not been able to see the type, and the species remains to me 

 somewhat enigmatical. I have before me some 59 examples, varying very greatly 

 among themselves both in colour and structure, which I cannot separate satisfactorily 

 owing to linking forms. Blackburn (who has kindly lent me the mutilated type of his 

 species) has separated oscillans from siibnifus by its different colour and by the lobes of 

 the pronotum being "considerably and regularly contracted towards the front," but 

 neither of these points appears more than varietal. R. koelensis also (judging from the 

 sadly mutilated type) is only a somewhat undeveloped form of S7t.brufns. The difference 

 in the neuration of the membrane seems to me also only variational. 



Hab. Hawaii, 4000 ft. (July, August) ; Kaumanu, 2000 ft. (January) ; Kilauea, 

 Hilo Road (June to August); above Hilo (December); Olaa (November). — Maui, 

 Haleakala, 4000 to 5000 ft. (May, October); Jao Valley (March).— Molokai (June). — 

 Oahu, Waialua, Koolau range, 2000 ft. (April) ; Kauoloa gulch (April) ; Honolulu, 

 2000 ft. (October); Pipturus (November). Its headquarters are in Hawaii.
