572 FAUNA HAWAIIENSIS 



We have only two immature specimens of this species, but I describe it, as it 

 makes a certain approach to the genus Atheta, the metasternal lamina between the 

 coxae being narrower at the tip and more pointed than usual in Dicstota, while the 

 general facies is very much that of Atheta. The antennae are — -for the size of the 

 insect — more long and slender than in any Diestota except D. sculpturata. The coarse 

 punctures on the head can be distinguished behind, though they are very obsolete in 

 front; the head is less rounded at the sides than usual. The thorax is a good deal 

 narrowed behind, and has a broad depression on the middle. The sculpture of the 

 elytra is extremely fine, and their colour is rather dark brown than black, a little paler 

 about the scutellum, but as the specimens are immature this may not be constant. 

 There is a well-marked delicate pubescence of the upper surface, and about the lateral 

 rhargins of the abdomen the pubescence is markedly longer and more conspicuous 

 and outstandinsf. The male has a lateral tooth on each side of the hind marmn of the 

 last dorsal plate, and several minute teeth between, as in most other Diestotas. 



Hab. Kauai, Makaweli, 2500 ft. 11. 1897 (Perkins). 



Group 3. Small insects. The punctuation of the head more or less obsolete. 

 (The line of demarcation between Groups 2 and 3 is quite arbitrary, D. liirida and 

 latmscula might be placed in Group 2.) 



(18) Dicstota litrida, sp. nov. 



Nigricans, pedibus sordide testaceis, elytris disco late testaceo ; sat nitida, sub- 

 tilissime pubescens, capite obsolete punctato, thorace elytrisque subtilissime punctatis. 

 Long. 2\ mm. 



This species, owing to the colour of the elytra and to the sculpture and pubescence, 

 has a very Athetiform appearance, but it appears to be congeneric with D. sitbplagiata, 

 &c. The head has the punctuation obsolete, though the large punctures can still be 

 detected. The thorax is strongly transverse, slightly narrowed behind. The antennae 

 are short and stout, but little different from those of D. crassicornis. There is only 

 a trace of a carina on the mesosternum, and the male characters are like those of 

 D. sordida, &c.

(19) Diestota latiiiscii/a, sp. nov. 



Supra subplanata, capite, thorace elytrisque nigricantibus, opacis, obsolete punctatis,

This is a rather broad and flat species, in form more similar to D. robusta than to 

 any other, but considerably smaller, paler in colour, with thinner antennae, and very 

 distinct by the sculpture of the anterior parts. The pubescence though scanty is rather
