396 FAUNA HAWAIIENSIS 



Very close to D. obfiisiis, but narrower, acuminate behind, with a differently shaped 

 and much more finely punctured thorax, and very delicate pubescence on the upper 

 surface. The colour is very much that of D. obtitsiis, fuscous-black or piceous, with 

 the elytra behind obscurely reddish. \\"e have only one specimen, which in general 

 structure seems extremely similar to D. odiiisns, the legs and antennae being however 

 a little more elongate ; the terminal joint of the hind tarsus is longer than in any other 

 species, and the last ventral plate is a good deal prolonged and a little bent at the apex 

 in the middle so as to be somewhat gutter-like.

(26) Droiiiacolus coucolor, sp. nov. 



Latiusculus, convexus, rufus, antennis pedibusque flavis, crebre subtiliter punctatus, 

 subnitidus, subtiliter flavo-pubescens. Long. 5 — '^^ mm., lat. 2 mm. 



The antennae are rather long and stout, one joint extending beyond the tip of 

 the thoracic angle, the fourth joint is small, scarcely so long as broad and a good deal 

 shorter than the fifth, terminal joint elongate. Thorax large, with large hind angles, 

 but no depression of the surface in front of them. Striation of elytra fine ; the punc- 

 tuation and pubescence on thorax and elytra are fine, but still render the surface 

 moderately dull; the thorax is about if mm. long, the elytra about 3 mm. Fourth 

 joint of the tarsi small, the terminal joint rather long. This is about the size of 

 D. boiivoiiloiri, but is considerably broader, and has broader sides to the mesosternal 

 cavity and a broader prosternal process, and a much shorter basal joint to the hind 

 tarsus. It is more nearly allied to D. obttisus, but besides the great difference in size 

 and colour, it is more finely punctate. Four specimens. 



The specimens were reared from the larval state, and the colour may therefore be 

 darker in fully mature examples. Some fragments found by Mr Perkins on Haleakala 

 in March, 1894, apparently belong to this species, and seem to be of much the same 

 coloration.

(27) Droniacoiits piger, sp. nov. 



Latiusculus, brevis, convexus, rutus, antennis pedibusque flavis, subtiliter flavo- 

 pubescens, subnitidus, thorace anterlus dense fortiterque punctato. Long. 4 — 4-^ mm. 



Very similar to D. concolor but smaller, more attenuate behind, and with a denser 

 and coarser punctuation ot the thorax, especially on the anterior part, and with a much 

 shorter terminal joint to the tarsi. Two specimens. 



This species seems really distinct. It has the hind angles of the thorax remarkably 

 long and attenuate. In size it connects the D. obtusiis forms with D. pachyderes,
