COLEOPTERA 387 



more dense below — and that the tarsi are reddish towards their tips. The antennae are 

 elongate, reaching, when in their grooves, quite as far back as the hind margins of the 

 middle acetabula, the 4th joint is rather longer than broad, and the fifth still a little 

 longer. Thorax rather closely and coarsely punctured, with a short channel on the 

 middle behind. Elytra feebly striate, with the punctuation dense at the base, but 

 scanty elsewhere, the suture raised and forming a minute spine at the tip. Under 

 surface densely punctate, and with a rather abundant pallid setosity. Except in size 

 the species varies but little. 



D. pcrkiusi and its close ally D. germauits have no relation to any of the other 

 Hawaiian Droiuacoli. The coxal laminae are much shorter, not reaching nearly 

 so far back as the ist ventral suture; the mesosternal cavity has broad margins; the 

 clypeus is emarginate in front ; the tarsi are stronger, with longer terminal joint and 

 claws. 



The two species are more similar to the Californian D. basalis. from which however 

 they are abruptly distinguished by the deep, definite and elongate antennal grooves. 



Hab. Hawaii, Maui. — -Hawaii: Kilauea, August, 1S95, 16 specimens (no. 574); 

 Kona, 3500 ft. 28. VI. 1895, - specimens. — Maui: Haleakala, 4000 ft. 31. in. 1894 

 (Perkins). 



On Maui fragments only, of two individuals however, were met with. I can find 

 no important difference from the Hawaiian specimens. 



(2) Dromaeolus gcrinaniis, sp. nov. 



Elongatus, angustus, nigerrimus, nitidus, pube albidescente sparsim vestitus, protho- 

 race canalicula mediana elongata. Long. 10 mm. 



Very closely allied to D. pcrkiusi, but rather narrower with shorter antennae and 

 tarsi, and the channel on the middle of the thorax longer. The eyes are rather smaller 

 and do not infringe on the line of the antennal groove, so that even in Bonvouloir's 

 arrangement the species would come into Dromaeohis. 



We have received only one example ; unfortunately after being examined it met 

 with an accident and is much damaged. It probably represents a really distinct species.

(3) Dromaeolus bonvoiiloiri Sharp. 



Fornax bonvoiiloiri Sharp, Tr. Dublin Soc. iii. 1885, p. 151. 



This little insect is distinguished by its uniform dull, infuscate red colour, with the 

 pubescence rather paler, flavescent ; the dense thoracic punctuation, and the narrow form 

 much acuminate behind. The antennae are moderately long and reach back quite as
