444 FAUNA HAWAIIENSIS 



minute pubescence. It is one of longer-antennaed species and has a broad head with 

 large eyes, the club of the antenna black. The thorax has the sides behind a good deal 

 explanate, but in front only very narrowly, it is rather densely and finely punctured, 

 minutely pubescent, the elytra have very shallow, obsolete grooves and obsolete punctua- 

 tion. The male has the apex of the pygidium elongate, and somewhat acute in the 

 middle, it is extremely finely punctate, the last ventral is very feebly bisinuate. The 

 punctuation of the abdomen is very delicate. 



Three males, taken at different times, agree with these characters. A specimen of 

 the other sex, taken on another occasion, is I believe the female of G. calvus ; it is rather 

 smaller, and has the thorax a little shorter and smaller, and the abdomen not quite so 

 delicately punctate. The hind margin of the pygidium is nearly straight truncate, 

 though sufificiently rounded to make the angles a little indistinct ; the last ventral is also 

 nearly straight, with a tuft of cilia on each side. All the specimens appear to be 

 immature ; they all have the elytra infuscate, but paler round the scutellum. 



I also assign to this species three individuals in which the colour is much darker, 

 the head, the thorax except at the sides, and the antennae and legs to a great extent 

 black. The smallest of these three examples is only 6 mm. long. One of these females 

 is from the island of Molokai.

A single very immature specimen differs but little from G. haleakalac, but has the 

 elytra more distinctly sulcate. It is certainly not G. latus, being too narrow, having the 

 thorax less explanate at the sides, and the pygidium more truncate than the male of 

 G. latus. It is probably another species. 



A second specimen (Oahu, no. 801, but no locality) is even more immature and 

 apparendy has the elytra less distinctly sulcate. 



Hab. Oahu, behind Mt. Tantalus, on Piptuiiis (no. 784, Perkins). 



(12) Gonioryctiis oaliucnsis, sp. nov. 



Haud latus, minus depressus, fiavo-ferrugineus, capite, thorace elytrisque plus 

 minusve fuscescentibus, fortiter punctatus, elytris subsulcatis, subnitidis. ? Long. corp. 

 5^^ mm., kit. 2^^, long, prothoracis i^:, lat. prothor. 2, long, elytr. 2^- mm. 



This species has the posterior angles of the thorax less acute than usual. The head 

 is broad, with large eyes, the antennae rather short. The thorax much rounded at the 

 sides in front, rather coarsely punctured, the disc unimpressed. The elytra are a little 

 shining, feebly sulcate, with rather coarse, but indefinite punctuation, the sides slightly
