Palixgenia javaxica, sp. nov. Plates I. & II. 1 d (forceps, 6 , legs, fore wing, and 

 parts of setse). 



Adult (dried) d . — Wings dark subtestaceo-cervinous, with opaque neuration ; the 

 veinlets along the terminal margin of the fore wing less sparse and better defined than in 

 the wing of P. tenera. Body faded above ; venter and setse subtestaceous, the genitalia 

 luteo-testaceous ; the setoe for some distance in the middle portion of their length are 

 furnished at the joinings with a few spreading hairs, longer and stronger than the hairs 

 of the universal pubescence. The fore legs and the hinder tibire and tarsi opaque 

 whitish ; hinder femora testaceo-lutescent ; fore tibia on the inner side at the tip armed 

 with a small more or less acute tubercle ; intermediate legs the shortest pair, hind legs 

 the longest, and more than half as long as the abdomen ; luigues of the hinder tarsi very 

 unequal, the lesser hardly visible ; those of the fore tarsus more nearly alike, and well 

 developed. The last two joints of each forceps-limb are together very nearly half as 

 long as the antepenultimate joint. Length of body, 6 , 19, wing 22-23"5, setoe about 

 60-70 mm. 



Sab. Orawang (Java occid.). Five examjjles in Leyden Mus. communicated to me in 

 1876 by Mhr. C. Eitsema. The MS. name by Van A'oUenhoven attached to one of them 

 (No. 50), being preoccupied in Ephemeridas, is not adopted. 



Palixgenia texera, sp. nov. Plate II. 1 e (wing and part of setae). 



Adult {dried) 6 . — TMngs dark cinereous, with the longitudinal nervures and the 

 coarser of the cross veinlets subpiceous or fuscous, and with the finer of these whitish or 

 edged with whitish when viewed obliquely so as to reflect light. Body discoloured, 

 genitalia pale testaceous, setae almost concolorous with the wings. Legs very short in 

 comparison with those of P. y««;a?i/(?«, the posterior femur not extending to beyond the 

 second abdominal segment ; fore legs faded (whitish ?), posterior femur subochraceous. 

 Pubescence of setaj composed of uniform hairs. Length of body 17, setai circ. 55 mm. 



Sab. Ardjoeno (Java orient.). One example in the Leyden Museum. A smaller 

 insect than P. javanica, having wings free from the least tint of testaceous, and with 

 more delicate neuration. 



Palixgexia papijaxa, Etn. Plate II. \f (wing and forceps, 6 adult). 



Palingenia papuana,\ Etn., Annal. Mus. Civ. di Stor. Nat. di Geneva, xiv. 398, woodcut a-f

 black. The fork of the anal nervure of the fore wing contains a single longitudinal 

 nervure. Sette pubescent with uniform hair. Fore femur in the 6 not much shorter 

 than the fore tibia ; intermediate tarsus about as long as the intermediate tibia ; hinder
