236 FAUNA HAUAIIENSIS 



them more or less aberrant, they connect by means of intermediate examples with the 

 type or with J/, vclox, a form doubtfully distinct from Af. epicuiiis. The most marked 

 departure from the average are examples in which the tibiae are dark in colour, those of 

 the hind legs being most conspicuously so: this condition I have labelled va.r./usii/>es. 

 Should Af. velox prove to be not distinct, it is likely to be found connected by a series 

 of these dark-lesfsred forms.

(10) Mctronienus velox, sp. nov. 



Niger, nitidus, antennis pedibusque testaceis, tibiis plus minusve infuscatis ; elytris 

 margine externo angustissime flavo, sat profunde striatis, apicibus post sinuositatem 

 parum elongatis : thorace versus margines rufescente. Long. 6^ — 7 mm. 



This is very closely allied to M. epicuriis, but is smaller, less robust, more shining 

 black, and has the elytra more truncate behind : the thorax is shorter, and the legs more 

 slender, and with the tibiae and the middle of the femora infuscate. 



H.-\.B. Oahu, Waianae mountains, lee side, February 1896, seventeen specimens. 

 No. 542. 



Tliis will probably prove to be a form of M. epicurus ; it will be noticed that it is 

 not stricdy localised, as M. epicm'us also occurs in the Waianae mountains.

Anchovienus f rat emus Blackburn, Ent. Mo. Mag. xiv. 1877, P- i45- 

 Of moderate size, rather depressed, moderately deeply striate, with broad yellow tip 

 to the elytra ; this colour is continued forwards along the sides but fades out before 

 reaching the shoulder, where only the upturned margin is pale. The species appears not 

 to be very variable. The specimen found on Pipturits is very large. 



Hab. Oahu. Not rare : under bark of trees at an elevation of about 2000 ft. 

 (Blackburn). Waianae mountains 2000 — 3000 ft., lee side, February 1S96, 32 specimens ; 

 on Pipturiis, back of Tantalus, August 1900, one specimen ; ridge Ceryone, N. of Pauoa 

 Vallev, November 1S92, one specimen (Perkins).
