COLEOPTERA 249 



latter feebly strigose. The elytra are rather broad at the shoulders, and all the striae 

 are remarkably deep, distinct and regular from base to apex ; a feeble crenation 

 or punctuation is seen in the depth of each stria. Legs short and stout. Six 

 specimens. 



Hab. Maui. Haleakala, 5000 ft., October 1896 (Perkins). 



(13) MecyclofhoTax daptimis, sp. nov. 



Nigricans, antennarum basi palpis pedibusque testaceis ; prothorace transverso, 

 basin versus fortiter angustato, supra transversim rugoso ; elytris ad latera late testaceo- 

 limbatis, profunde striatis, striis haud punctatis. Long. i\ mm. 



One of the smallest of this division ; very distinct. Antennae dark, yellow only at 

 the extreme base. Thorax small, very strongly narrowed behind, so that the base is 

 narrow, hind angles obtuse not at all rounded ; the upper surface covered with fine 

 transverse wrinkles, the median channel distinct, the anterior impression and the basal 

 sculpture indefinite, the lateral margin but little raised even at the hind angle. Elytra 

 strongly rounded at the shoulders, yellow, each with a very large black mark near the 

 suture (the two black marks separated only by the yellow suture), very deeply and, for 

 the size of the insect, broadly striate, so that the striae appear crowded. Undersurface 

 of head reddish. Legs clear yellow ; ventral segments more or less yellow at the hind 

 margins. Forty specimens. 



Hab. Maui. Haleakala, 5000 ft., April and June 1894 (Perkins). 



(14) Mecyclothorax inaeqnalis, Blackburn. 



Cyclotkorax inaeqita/is Blackburn, Ent. Mo. Mag. xv. 1877, p. 157. 



A beautiful and very distinct insect ; the upper surface of a peculiar submetallic 

 coloration and very dull ; the elytra have several foveoles on the third interstice and 

 others on the fifth ; the striae are subobsolete and irregular, and are rendered more 

 indistinct by the peculiar " bloom " of the surface. The thorax is transverse with a 

 somewhat narrow base, and a short constricted basal part, with the hind-angles rect- 

 angular. The species may therefore be considered as one with cordate thorax. It is 

 apparently very rare.

I can give but little information as to this species. I have before me four individuals 

 that I refer to it with confidence. According to them it is a species with a general 

 resemblance in colour and form to Thriscothorax iinctus but with a longer thorax, the
