332 MR. R. S. BAGNALL ON TWO NEW 



one at each angle o£ the first abdominal tergite ; a very small one and a 

 longer one at each posterior angle oi: the second segment ; a short one and 

 two long ones at the posterior angles o£ each o£ the segments three to seven, 

 which gain in length posteriorly. A single pair o£ weak, wing-retaining 

 spines placed posteriorly on each o£ the segments three to six. In addition 

 to the spines at the posterior angles o£ the seventh segment there are marginal 

 spines present, and the eighth segment has a moderately long spine at each 

 posterior angle as well as slightly shorter marginal spines. 



c^. The male is smaller and has the abdomen more slender. It differs 

 from the female in having the fore-£emora and tibia3 greatly enlarged, the 

 femur being strongly inflated and having the surface very glossy ; and also 

 in the possession of a very long and acute fore-tarsal tooth. The tube is 

 six times as long as the ninth abdominal segment, and the ninth sternite 

 is furnished with a pair of long bristles. 



Habitat. One male and one female, Caracas, Venezuela (Meinert). 



Type, In the Copenhagen Museum. 



Genus AcTiNOTiiRirs, nov. 



$ . Head about twice as long as wide and only slightly swollen at basal 

 third, a little more than twice the length of prothorax ; vertex slightly 

 produced beyond eyes. Cheeks armed with two pairs of stout spines. 

 Mouth-cone reaching more than halfway across presternum. Eyes medium- 

 sized ; anterior ocellus placed at extreme vertex and widely separated from 

 posterior pair ; postocular bristles short and anteocular pair obsolete. 

 Antennse very long and slender, at least three times the length of head ; 

 each basal joint armed with a strong dorsal spine near apex. 



Prothorax transverse. Fore-legs slender, and fore-tarsus with a minute 

 tooth. Pterothorax much wider than prothorax ; metascutum armed with a 

 jiair of spine-set tubercles, one on each side of the mid-line and near the 

 anterior margin. Wings long and slender ; median vein strong, and reaching 

 for almost the entire length of wing. Hind and intermediate legs long 

 and slender. 



Abdomen as wide as pterothorax, long and gradually narrowed from base 

 to tube ; each of the segments two to eight more or less produced laterally at 

 apical third for seating of bristles ; strongly sculptured dorsally. Tube very 

 long, sparsely clothed with long, slender white hairs. Only a single pair of 

 wing-retaining bristles on each of the segments so furnished, and a pair 

 of rather long stout spines placed laterally below the abdominal bristles, 

 which latter are moderately long but slender. 



Type, Actinotlirips longicornis, mihi.
