striae curve slightly inwards in its median part. The mesosternum is rugosely punc- 

 tured. Wings not examined. Seven specimens. 



Hab. Maui, all from Haleakala, 5000 ft. and over (no. 381, Perkins). 



(24) Acritiis pcrkinsi, sp. nov. 



Sat late ovalis, fusco-testaceus, nitidus, supra obsolete punctulatus ac interdum 

 inaequalis ; pedibus longis ; prothoracis basi punctata ac in medio haud profunde 

 impressa ; prosterno haud angusto ; mesosterno impresso, rugose punctato. Long, 

 circa i^ mm. 



This rather broad, long-legged species is sometimes smooth, but frequently has a 

 peculiar wrinkled appearance due to the presence of minute punctures and inequalities. 

 In general form it is very like A. a7igiististernii})i, but is at once distinguished by the 

 prosternum, which is shorter, and has the keel (PI. XV. fig. 23) little more than twice 

 as long as its breadth in the median portion. There is also a difference in the sculpture 

 of the base of the thorax. In A. angusttsteriniiii the basal punctures and sculpture 

 form a transverse line, just in front ot the actual base, most marked in the middle, and 

 extending some distance on either side. In A. perkinsi there is a shallow median 

 depression, not extending far transversely ; and on either side, as far as the posterior 

 angle of the thorax, the actual base is punctured, and so has a beaded appearance 

 (PI. XV. fig. 24). 



The surface of the mesosternum is rugose. Wings not examined. Ten specimens.

I have examined the type and a smaller specimen of this species, found by Black- 

 burn in Hawaii. The legs are conspicuously slender and long. The general form is 

 rather narrow. A high power shows the surface to have some minute punctures and 

 inequalities ; there is a slight median impression at the base of the thorax. Keel of the 

 prosternum about twice as long as broad, the front margin only slightly wider than the 

 base, the surface rather convex. A marked depression is present on the mesosternum 

 and front part of the metasternum. Length of the type i;^ mm. The wings are much 

 reduced, but to exactly what extent 1 have been unable to determine. 



Hab. Hawaii (the type from Mauna Loa, over 4000 ft., Blackburn). .'' Lanai 

 and Maui (see below). 



Mr Perkins has obtained no specimens quite agreeing with the typical A. longipes, 

 but there are several specimens from other islands, the relation of which to A. longipcs 

 and to one another is somewhat doubtful. Blackburn (op. cit. p. 226) states that he 

 found small specimens, apparently referable to A. longipes, on Lanai and Maui.
