COLEOPTERA 439 



and in the middle the hind margin is much elongated while the lateral angles have 

 entirely disappeared. In the female the pygidium is convex before the tip ; the tip is 

 rather abruptly bent down, and its hind margin is produced so as to form an angle in the 

 middle, each of its hind angles is sharp and bears an extremely minute pencil of hairs ; 

 the last ventral receives the tip of the pygidium, it is therefore just perceptibly prolonged 

 in the middle, and has a large pencil of hair on each side. Forty-two specimens.

 &c., Perkins). 



(8) Goniothorax eremitus, sp. nov. 



Minus convexus, sat elongatus, fusco-rufus; thorace ex parte majore rufo, transverso, 

 posterius angustato, elytris obsoletius sulcatis, minus obsolete punctatis. ? Long. corp. 

 ']\ mm., lat. 2f, long, prothoracis if, lat. 2, long, elytr. 3 mm. 



Closely allied to G. perkiusi but less elongate, with a shorter head, the thorax more 

 curved in front, the elytra with some slight depressions and rather differently sculptured. 

 In these points nearer to G. iiiacqualis, but the male has not the remarkable characters 

 of that species, and the tibiae have no thickening at the tip. The pygidium of the male 

 is but little convex ; the last ventral has a broad, but not very deep large impression 

 and is not prolonged in the middle behind. One specimen. 



Hab. Hawaii, Kilauea, viii. 1896 (no. 656, Perkins). 



(9) Goniothorax fovcatus, sp. nov. 



Nigricans, antennis pedibusque testaceis, thorace abdomineque rufescentibus ; 

 minus elongatus, thorace transverso; elytris inaequalibus, vix subaenescentibus, abdomine 

 profunde foveolato. ,? Long. corp. bh mm., lat. 2-^, long, prothoracis i|-, lat. prothor. 2, 

 long, elytr. 2|- mm. 



This species approaches the genus Goiiioiyctus, but the femora are well prolonged 

 beyond the sides of the thorax, and the claw-joint of the tarsus is remarkably long. 

 The upper surface shows numerous depressions, on head, thorax, elytra and abdomen, 

 the foveae on the latter being remarkably deep. The sides of the thorax are much 

 rounded in front, and slightly sinuate behind, the sulcation and punctuation of the elytra 

 are both indistinct ; and the legs are more slender than in the other species of the genus. 

 In the male the pygidium is rather narrow at the tip ; the last ventral has a shallow 

 depression along the middle, and the hind-margin is slightly bisinuate. One specimen'. 



The uneven upper surface of the body, caused by numerous depressions, is 

 remarkable. 



Hab. Molokai, 4500 ft. 11. ix. 1893 (no. 159, Perkins). 



' I have recently seen a second specimen captured by Mr Perkins in 1903. It is of the same sex, 

 and only difters in the hind angles of the thorax being a little less acuminate.
