COLEOPTERA 469 



The species was described from Maui by Mr Blackburn. I believe our series 

 from Hawaii is the same as Mr Blackburn's type, but as this is in bad preservation it 

 is not quite certain. 



Hae. Maui, Hawaii. — Maui ; Haleakala, 4000 ft. (Blackburn). — Hawaii ; Olaa, 

 Kilauea, above Hilo, 1800 ft. (Perkins). D. S. 



(15) Enpdiiius onialioides. Sharp. 



Bi'achypcplus onialioides Sharp, Tr. ent. Soc. London, 1S7S, p. 136. 



This species was described from four specimens. We have now a series of 49 

 individuals. The species is in some respects very close to E. subapcr. It differs in 

 having a much more scanty and delicate pubescence, especially on the pygidium and 

 last ventral segment, which are far less coarsely punctuated than in E. snbaper. It is 

 a comparatively elongated, smooth, and even species. A few specimens vary in the 

 direction of E. snbaper, in having the pygidium rather more coarsely punctuated. The 

 elytra frequently have rather larger punctures, and are smoother. E. onialioides differs 

 from both E. snbaper and E. aper in having the male supplementary segment not at all 

 tapering, but rounded, or truncate in the middle. 



The male pygidium is truncate, scarcely emarginate, broader at the end than that 

 of E. snbaper. Female p)"gidium more rounded than that of E. snbaper. 



The males as a whole are darker than the females, but one female is the darkest of 

 all. A few males approach the condition of the van dimidiatns of allied species, having 

 the anterior and outer parts of the elytra dark, and the posterior and inner parts of a 

 lighter, yellowish colour ; and a small light patch at the base of either elytron near the 

 scutellum. 



H.\B. Oahu, Hawaii. It is a characteristically /vrjr/;/tV/<7-haunting species, being 

 found in the flowers, at the bases of the leaves, &c. — Oahu ; apparently widely distributed, 

 but not many found together; Waianae mts. about 3000 ft. (no. 547); Konahuanui Ridge 

 (no. 783); mountains near Honolulu, 2000 and 3000 ft. (Perkins); Blackburn also records 

 it (Tr. Dublin Soc. iii. 1885, p. 230) as occurring in considerable numbers in Oahu, and 

 notes its preference {or'Freyeuietia. — Hawaii ; recorded from this island, as well as from 

 Oahu, by Blackburn (I.e.). 



(16) Enpetinns brevicollis, sp. nov. 



Latus, depressus, fusco-testaceus, nitidus, limbo, abdominis aplce pedibusque flavis ; 

 antennis brevibus, clava nigricante ; prothorace fortiter transverse, haud rugoso, angulis 

 posterioribus obtusis ; elytris parum inaequalibus, regulariter punctato-striatis ; abdomine 

 obsolete punctato. Long. ■^^^ lat. \\ mm. 



This species has short antennae (PL XIV. fig. 19), with the seventh, eighth and 

 ninth joints shorter than usual. The lateral margin of the elytra is moderately broad.
