2 50 FAUNA HAWAIIENSIS 



head and thorax are red or nearly black, as the case may be ; the thorax is rather long, 

 gently narrowed behind, with however only an imperfectly formed constricted basal part. 

 The elytra are shining, rather flat, with very definite yellow margin, and with about five 

 series of fine punctures, the outer two of which are extremely abbreviated and indistinct ; 

 the legs are red, with a broad infuscation of the tibiae, which however is variable. 



Besides these there are four or five specimens that may belong to the species, but 

 if they do it must be an extremely unstable one. Mr Blackburn says if he understands 

 it right, " the species has the unusual character of extreme variableness in the striation 

 of the elytra." 



Hab. Hawaii. Mauna Loa, under bark near the mouth of the crater Kilauea 

 (Blackburn). Kilauea, in August 1895, 1896; Kona, Sept. 1892, 4000 ft. (Perkins). 

 The specimens from Kona are those that doubtfully pertain to the species. 



(16) Mecyclothorax ovipennis, sp. nov. 



Fusco-testaceus, antennarum basi, palpis pedibusque testaceis, elytris ad apicem 

 late pallidis ; prothorace cordato, basi elongata; elytris ovatis, convexiusculis, subtiliter 

 striatis, striis vix perspicue punctatis. Long. 4 — 4^ mm. 



Plate VII. fig. 6. 



A rather narrow species, less dark in colour than usual, with narrow, convex elytra, 

 and the neck formed by the base of the thorax unusually long. The thorax is much 

 rounded at the sides, near the base parallel-sided, the hind angles rectangular, almost 

 acute ; the surface somewhat shining, very finely wrinkled on the disc ; the anterior 

 impression obscured by longitudinal strigosities, the median channel distinct, the base 

 not much punctate. Elytra narrow and convex, almost regularly oval, their colour in 

 large part dark, but largely yellow at the tip, the yellow colour extending somewhat 

 forwards along the suture and sides ; they are finely striate, six striae on each are 

 distinct, the outer or seventh stria indistinct. Legs pale yellow. 



About fifty specimens. 



The species varies much as to the depth of the dark colour, but not much in other 

 respects. 



Hab. Maui. Haleakala, 4000 — 6000 ft., March 1894 (Perkins).

(17) Mecyclothorax iterahis, sp. nov. 



Elongatus, niger, elytris viridi-micantibus, palpis, antennarum basi pedibusque 

 testaceis, tibiis plus minusve fuscescentibus, antennis extrorsum obscuris ; thorace 

 elongato, basi constricta subelongataque, lateribus tenuissime marginatis ; elytris fere 

 estriatis, sericeo-micantibus. Long. 5^ — 6 mm. 



Head broad, with prominent eyes, basal three joints of antennae pale red, the 

 others more ob.scure. Thorax elongate, with a comparatively long and abrupt basal
