THE CANADIAN ENTOMOLOGIST. 247 



the anterior lobe of the pronotum ; first segment of antennae reaching 

 beyond the head, fourth segment the longest, fusiform ; rostrum reaching 

 to the fore coxce. The collar well marked, not as wide as the anterior 

 lobe ; the latter nearly twice as wide as its length, laterally rounded, 

 basally very slightly wider than in front ; posterior lobe finely but sparsely 

 punctured, raised and rounded behind, scarcely shorter medially than the 

 anterior lobe, very distinctly vvider than the head, its lateral margins 

 diverging at first obtuse-angularly, then turning sharply parallel with the 

 long axis of the body; posterior margin very lightly emarginate. Scutellum 

 medially carinate on the posterior two-thirds. Fore femora incrassate 

 and spinose, tibiae not toothed, but apically a little widened and subbifid. 



Length, S, s}i mm.; $, 4 mm. 



Hab.: Hawaiian Archipelago (introduced), now spread over Kauai, 

 Kekaha (F. W. T.); Oahu, from sea level to Mt. Tantalus, 1,500 feet 

 (R. C. L. P., W. M. G., G. W. K.) ; Maui, Olowalu (O. H. S.); comes 

 frequently to light. 



In examples not fully matured the collar and posterior lobe of 

 pronotum may be dark ferruginous, instead of black. 



The types {S 9) ^re in my collection.* 



Fam. Reduviid/e. 

 Triatoma rubrofasciatus, DeGeer. 



Probably originally a native of Brazil, now widely distributed. It is 

 found in these Islands near cottages of the poorer sort. 



Zelus peregrifms, Kirkaldy. 



Mr. O. Heidemann has {in litt.) identified this as identical with Z. 



jRefiardii, Ko\ena.\.i (1856, Bull. Soc. Nat. Moscou, XXIX, 460, Pi. Ill, 



fig. 2), from California, but I am not disposed to admit it on present 



evidence. Kolenati's figure is useless, and he states that the apex of the 



femora and base of the tibiae are intensely sanguineous, which I do not 



consider them to be, at least noticeably. The anterior lobe of the 

 pronotum is also not very distinctly quadrituberculate, nor is the abdomen 

 entirely lurid. Z. Renardii has not to my knowledge been redescribed 

 since 1856. 



Miln^ gen. nov.f 

 Differs from Reduviolus, \V. Kirby, by the incrassate first segment of 

 the antennae and the prominent blunt spine arising well in front of the 

 antennal insertion from the side of the head, which I formerly overlooked, 

 but which has been pointed out to me by Dr. Perkins. 



*Since writing this I have seen specimens from Australia and Viti. 

 \Milu is the Hawaiian ruler of the dead.
