ages of the male are slender and not widened at tip (in E. spectabilis 

 they are widened at tip and acute on inner side). Expanse 43 mm. 



Type. — cf. From Magnet, Tasmania (Lea). 



Easily distinguished from E. spectabilis by the violaceous 

 wings as well as by the male genitalia. 



PSOCIDAE. 

 Myopsociis eiiderleiiii n. sp. — Related to M. muscosus Ender. 

 from Japan. The markings of the wings are very similar, the dark 

 spot on the union of the cubitus and the median is here larger and 

 darker colored, the stigma is pale, with a few faint dark dots near the 

 costa, and there are more pale spaces along the veins in the apical 

 part of the wing. The antennae and legs are pale grayish ; head 

 brownish-yellow, unmarked. The venation is similar to M. muscosus, 

 except that the stigma is a little more swollen at tip, and the outer 

 side a little more oblique ; the median cell is rather broader and the 

 cross-vein from it to the hind margin shorter than in M. muscosus ; 

 the forking of the radial sector is also rather farther out than in that 

 species. Length 5 mm. 



Type. — cf . From Los Banos, Philippines (Baker). 



MANTISPIDAE. 



In 1910 Dr. Enderlein published an excellent classification 

 of the Mantispidae, but in several points it can be improved. 

 The length of the radial cells is of such a comparative char- 

 acter and so gradual in the variation from one species to 

 another that it can hardly be used as a generic character ; 

 the number of branches of the radial cells varies in some spe- 

 cies. M. indica is given by Enderlein as type of Mantispilla 

 with but one branch from the first radial cell, and so figured 

 by Westwood, yet in one specimen of the type series (in 

 British Museum) the first radial (as others) has two 

 branches. However I think that Mantispa may be divided 

 according to whether the pronotum is hairy or not, and by 

 this Mantispa and Mantispilla remain, but most of the spe- 

 cies are transposed from one genus to the other. Entano- 

 fieiira falls as a synonym of Mantispilla. 



Dr. Enderlein separates Anisoptera and Trichoscelia also 

 according to the number of branches to the first radial cell, 

 Trichoscelia having but two ; yet in the type specimen of the 

 genotype {T. {cjiella) there are two and a half, that is the
