(7) Dicstota carina fa, Sharp. 

 Diestota caHnata Sharp, Tr. ent. Soc. London, 1880, p. 41. 

 Hab. Oahu, Honolulu (Blackburn). 



(8) Dicstota incognita, Blackb. 



Diestota incognita Blackb., Tr. Dublin Soc. ser. 2, iii. p. 121. 



So far as I can judge from the type — which is in very bad condition — this species 

 must be very close to D. carinata. 



Hab. Hawaii, "a single specimen was taken by beating flowers in a mountain 

 forest on Hawaii," 4000 ft. (Blackburn). 



(9) Dicstota robusta, sp. nov. 



Robusta, subdepressa, nigra, palpis fuscis, pedibus sordide rufis ; capite fortius 

 punctato, thorace fortiter transverso, dense fortiterque punctato, elytris dense subtiliter 

 ruguloso-punctatis. Long. 4 mm. 



Antennae short and stout, penultimate three or four joints transverse. Head short 

 and broad, very coarsely punctate. Thora.x short, flat along the middle, quite dull, 

 densely punctured. Elytra much longer than thora.x, dull, finely but rather roughly 

 punctate. Legs short ; metasternum strongly carinate, the carina extending quite to 

 the tip. The male has a long slender, slightly curved tooth on each side of the hind 

 margin of the last dorsal plate, and between these seven smaller teeth. All the teeth 

 are well separated and blunt at the tip though not knobbed. Five specimens. Also one 

 of a slight variety with rather denser and finer punctuation, and slightly different male 

 characters. 



Hab. Hawaii, Hilo, on decaying stem of tree Lobelia, 2000 ft. i. 1896; the variety, 

 Kaumana, 2000 ft. i. 1896 (Perkins). 



(10) Dicstota occidentalism sp. nov. 



Nigricans, antennis fuscis, palpis pedibusque sordide testaceis ; capite lato, .sat 

 fortiter sed parum profunde punctato ; thorace elytrisque subtili-ssime sculpturatis, illo 

 fortiter transverso. Long. 2i\ ""tti- 



This is one of the species that exhibits the sculpture of the head as a transition 

 between coarse and fine sculpture: the impressed punctures on it are much less deep than 

 they are in D. robusta, but rather more distinct than they are in D. latiuscula ; from the 

 latter species it is well distinguished by the more slender, slightly longer, tarsi. The 

 mesosternum is not carinate. I have seen only one example, a female. 



Hab. West Maui, mts. 4000 ft. from Ereycinetia in 1894 (P'erkins).
