As indicated by the synopsis of the South American genera of 

 Phalangopsitidse, the representatives of the present genus are without 

 auditory openings on the anterior tibiae, hence possibly without 

 stridulating apparatus as well. Two species have been recorded from 

 tropical America prior to this time. Now specimens are at hand which 

 seem to indicate a third. 



61. Arachnomimus bahamaensis sp. nov. 



Moderately large and rather robust, with annulate anterior and 

 middle legs. Dark wood-brown, becoming almost black on the 

 occiput, pronotum, and base of the abdomen above, varied with bands 

 and blotches of paler, almost dirty white. 



Head short, a little narrower than the anterior margin of the pro- 

 notum, the eyes prominent, pyriform, the apex or narrower portion 

 below; the apex of head slightly advanced between the antennae 

 into a short rostrum, the anterior ocellus large, situated in a depression 

 at the top of the vertical front and immediately back of a prominent 

 transverse ridge, posterior ocelli also rather large and located fairly 

 close together, but far to the rear of the anterior one, thus forming an 

 acute triangle. Antennae long and slender. Pronotum nearly twice 

 as broad as long, the sides a little rounded, slightly wider at the base 

 than the apex, both margins nearly straight; the lateral lobes nar- 

 rowed posteriorly, both the anterior and posterior angles rounded. 

 Body entirely ai)terous. Anterior and middle legs long and slender, 

 hind legs also moderately long, the femora robust at base, slender at 

 the apex, the hind tibiae serrate with 4 : 4 spines on their apical half,
