524 FAUNA HAIFA II ENSIS 



The general form is decidedly depressed. The prothorax has numerous fine 

 punctures. In the median basal region is an impressed and shallowly rugose arc, 

 bounded in front by a well-defined, transverse, slightly arcuate line. Elytral punctures 

 sometimes very fine points, scarcely drawn out, sometimes fine elongate scratches ; 

 oblique stria near the shoulder very slightly marked. Prosternum about 2\ times as 

 long as the breadth at the base, the striae curving towards one another medially, slightly 

 divergent anteriorly, front margin of nearly the same width as the base. Mesosternum 

 rugulose, with a conspicuous, roughly triangular impression. Punctures on the meta- 

 sternum and first abdominal segment fine and not verj- close. 



The single specimen from Lanai agrees in colour and size with the type, but in 

 sculpture approaches a little to A. eutretus. Eight specimens. Wings not reduced, 

 examined in five Oahu specimens. 



Hai!. Oahu, Lanai. — Oahu ; seven specimens from the mountains near Honolulu, 

 VIII. 1900 (no. 785, Perkins); also one specimen, previously labelled " Aeletes basalis 

 van", from the Waianae mts. (Blackburn). — Lanai; near Waipaa, about 2000 ft. (no. 104, 

 Perkins). 



(16) Acritus eutretus, sp. nov. 



Depressus, oblongus, piceus, nitidus ; A. suhbasali affinis, sed major ; prothorace 

 subtiliter nee dense punctato, ante basin in medio rugoso, linea impressa arcuata; elytris 

 subtiliter sed conspicue aciculatim punctatis; prosterno longo, ang'usto, striis subparallelis ; 

 mesosterno impresso, parum rugose punctato, metasterno subtiliter ];)unctato. Long.

Distinguished from A. subbasalis by the much larger size and darker colour, and 

 by the sculpture of the elytra, which are marked with numerous fine punctures, drawn 

 out before and behind into \ery fine, much elongated scratches. This iorm of sculpture 

 ceases abruptly towards the shoulder in the region of the posterior oblique stria in the 

 three Hawaii specimens ; in the one from Oahu the scratches do not cease in the 

 humeral area, but are altered in direction, and oblique. The prosternum is over twice 

 as long as its breadth between the striae in the median part, and its breadth alters but 

 little throughout its length. 



It is po.ssible that this form may prove to be a large and marked variety of 

 A. subbasa/is, but with the material at hand it seems better to give it a name. Four 

 specimens. Wings not reduced.
