684 FAUNA HAWAIIENSIS 



the swollen part being furnished with five or six spines ; vertex slightly raised in the 

 form of a hump. 



Mouth-cone blunt and reaching only one-third way across the prosternum. Eyes 

 small, occupying laterally more than one-fifth the length of head, moderately finely 

 faceted ; post-ocular spines placed far back and about twice as long as the eye. 

 Posterior ocellus overhanging and looking forward, and the posterior pair on a line 

 drawn through centre of eyes. The antennae are unfortunately broken off with the 

 exception of the first four joints, the second and third joints are sub-equal claviform 

 with the distal half practically parallel, and have the stems shaded with a reddish- 

 yellow colour. There is a pair of short and somewhat obtuse sense-cones on each of 

 these joints. 



The prothorax is very massive, as long as the head and two-thirds as long as 

 broad. The mid-lateral angles are broadly rounded, whilst the notum does not reach 

 to the lateral margin, being only four-fifths as broad as the total breadth of the pro- 

 thorax. All the spines are apparently present ; the pair at the posterior margins are 

 long, the mid-lateral pair slightly shorter, the posterior-marginal pair shorter again, and 

 the pair at anterior angles shortest of all, and inwardly curved. The anterior-marginal 

 pair are either very minute or obsolete. 



The fore-coxa is armed with several short, stout spines. The fore-femur is nearly 

 twice as long as the head and about two and one-quarter times as long as broad through 

 the middle. The fore-tibia is very broad and placed in such a position on the type slide 

 that its true length cannot be estimated, and the figure probably shows this tibia larger 

 than it should be. The fore-tarsus is armed with a very broad, strong tooth. 



The pterothorax is not as broad as breadth across fore-coxae, and only two-thirds 

 as long as broad. The wings are vestigial and take the form of a small pad from 

 which spring two bristles. The hind and intermediate legs are rather short and stout, 

 each is furnished with a series of short spines and each tibia with several short and 

 slender ones and a few longer bristles near tips. 



The abdomen is slightly broader than breadth across fore-coxae and has the 

 segments one to seven strongly transverse, narrowing from the sixth segment to the 

 tube ; the seventh segment is laterally rounded at its basal half The tube is twice as 

 broad at base as at its apex, longer than any abdominal segment, and five-sevenths the 

 length of head. The terminal bristles are not strong and about three-quarters the 

 length of tube, whilst the abdominal bristles are long but only moderately strong. 



% unknown. 



Hab. Hawaii ; Kona, one male from under a rotten log, 4000 feet (Perkins). 

 Dr Perkins makes a note that he saw no other specimen of that species.
