574 FAUNA HAWAIIENSIS 



(22) Dicstota rufescens, Sharp. 



Diestota riifescciis Sharp, Tr. ent. Soc. London, 1880, p. 42. 



A broad insect of brown colour, very dull, the sculpture of the head extremely 

 obsolete, the elytra rather strongly granulate-sculptured. 



Hab. Kauai, on Freycinetia in the mountain forests (Blackburn). 



(23) Diestota latifrons, Sharp. 



Diestota latifrons Sharp, T. c. p. 40. 



I have seen no second specimen of this species. It appears to be closely allied to 

 D. mfescens, but not so broad, darker in colour, and with the granules of the elytra not 

 so distinct. 



Hab. Kauai, August, 3000 ft. on Freycinetia (Blackburn), 



(24) Diestota palpalis, Sharp. 



Diestota palpalis Sharp, T. c. p. 40. 



Apparently closely allied to D. crassicoriiis but the antennae are longer, only the 

 penultimate three joints being transverse, and the terminal joint considerably longer. 



Hab. Hawaii, Mauna Loa, 4000 ft. near the crater (Blackburn). 



(25) Dicstota crassicoriiis, sp. nov. 



Nigricans, antennarum basi, palpisque fuscis, pedibus sordide testaceis; capite 

 obsolete punctato, thorace elytrisque subtilissime sculpturatis. Long. 2f mm. 



This is smaller than D. occidentalis and D. matnensis, and is readily distinguished 

 by the antennae which are much shorter, the 4th joint being small, scarcely so long as 

 broad, the 5th to loth strongly transverse. The large punctures of the head, though 

 very obsolete, can still be distinguished. Though very similar to D. sordida, brevicornis 

 is readily distinguished from it by the thicker antennae and the more obsolete cephalic 

 sculpture. The mesosternum is not carinate. The male has a tooth on each side of the 

 last dorsal plate, and several minute denticles between them, as in many of the allied 

 forms. 



Hab. Maui, Haleakala, 5000 ft. October 1896 (no. 661, Perkins). 



(26) Diestota parva. Sharp. 



D. pai'va Sharp, Tr. ent. Soc. London, 1880, p. 39. 



This obscure species must not be confounded with D. sordida. It is a little smaller, 

 the length being about 2 mm., the surface is very dull, and the punctuation of the head is 

 more obsolete ; the antennae are proportionately shorter and thicker. Our small series is in
