COLEOPTERA 26 



J 



Elytra with only a sutural stria which is punctate at the base. 



Mr Blackburn's specimens in the British Museum do not exhibit a seta ; but they 

 have been much damaged by dirt and mould, and I think are this species. 



Hab. Hawaii. Mauna Loa, about 3000 ft., under a stone, one specimen (Black- 

 burn). Kilauea, September 1896, three specimens (Perkins). 



(15) Thriscothorax paradoxus, Blackburn. 

 Cyclothorax paradoxus Blackburn, Ent. Mo. Mag. xvi. 1879, p. 108. 



Plate VII. fig. II. 



Distinguished by the red colour, the surface as if varnished, and the strongly 

 transverse thorax much narrowed behind, but without the slightest sinuation, so that the 

 hind angles are very obtuse, and the sides are only narrowly turned upwards at the base. 

 The anterior transverse impression is very deep, and the median channel strongly 

 marked. There are only two striae on each elytron. Mr Blackburn found but one 

 specimen and Mr Perkins has just sent me another, which agrees with it except in being 

 smaller. Mr Perkins has also sent a specimen of a Mccyclothorax from the same island, 

 that is extremely like T. paradoxus. 



Hab. Hawaii. Mauna Kea, 3000 ft., under bark of a tree (Blackburn). 



(16) Thriscothorax disccdens, sp. nov. 



Niger, antennis rufo-obscuris, earum basi palpisque testaceis, pedibus fusco- 

 testaceis ; prothorace fortiter transverso, basin versus angustato, basi angusta ; elytris 

 striis punctatis profundis circiter tribus, externe tantum stria altera, munitis. Long, 

 vix 4 mm. 



Readily recognised by the deep striae next the suture, while outside these there 

 are only one or very abbreviated striae, and by the short thorax, greatly narrowed 

 behind with obtuse angles. The anterior transverse impression is rather indefinite, 

 the median channel very distinct, the narrow base but little punctate. The short 

 striae on the elytra do not commence at the base, with the exception of the sutural 

 one which is deep from base to the tip, the fourth stria is very short, and there are 

 traces of a fifth outside it. The legs are much infuscate, especially the tibiae and 

 the bases of the femora. Four sj^ecimens. 



Van teriuinalis, var. n. 



One specimen, from Olaa, is rather smaller, and has the elytra broadly yellow at 

 the tip, the raised margins of elytra and of thorax are also yellow, as well as the 

 legs, there are five striae all of which are strongly punctate. It is possibly a distinct 

 species. 



Hab. Hawaii. Kilauea (Perkins).
