preceding' species, the prosternum is distinctly punctured, an uncommon character in 

 Hawaiian Acriti. The metasternal punctures become very small over a little area in 

 the middle; meso-metasternal suture very faint. 



This species forms in many respects a transition between A. kauaiensis and the 

 general type exemplified l^y A. maniac, kukniac and piinctatus. It is much like 

 A. kauaiensis, having the apices of the elytra a little rugose ; but is distinguished by 

 smaller size, microscopically rugulose surface, and absence of fronto-clypeal suture. 

 Wings not examined.

We have only t\vo specimens. The species is closely allied to A. punctatus and 

 A. hikuiae, but clearly distinguished by its punctuation and the form of the prosternum. 



The prothorax is more strongly punctured than in either A. punctatus or A. 

 kukuiac. The elytral punctuation is stronger than that of A. kukuiac, not so close and 

 strong as that oi A. punctatus ; the humeral area where the punctuation becomes rather 

 obsolete is not specially marked. Pygidium more strongly punctured than that ot 

 A. punctatus. In the two preceding species the punctuation of the thorax is very much 

 finer and shallower than that of the elytra ; in this species there is much less difference, 

 the thorax and elytra being very much alike in this respect. Prosternum with the keel 

 finely punctured, slightly convex, less nearly oblong, being slightly narrower with 

 striae more widely divergent in front. The punctures of the metasternum become 

 much smaller in the middle, but there is not (as in the two preceding species) a definite 

 area where the punctuation is obsolete. One specimen has two vague oblique striae 

 near the shoulder of either elytron. Transverse suture present on the head just 

 before the antennae. Wings not reduced. 



Hab. Maui; Haleakala, between 4000 and 5000 ft. v. 1896 (nos. 599, 601, 

 Perkins). 



(8) Acritus kukuiae, sp. nov. 



Oblongo-ovalis, A. punctato aftinis, sed elytris minus fortiter punctatis, punctis 

 ad humeros sat late obsoletis. Subtus fortiter sed rarius punctatus. Long, i^ mm. 



We have three specimens. The species agrees with A. punctatus in all respects 

 except the following. The surface is rather smoother and more shining ; the elytral 

 punctures are smaller and the interspaces larger; there is a considerable area towards
