New or Little Knoivn Sjjecies of the HemerobiidcB. 443 



junction is a very small horizontal narrow fuscous patch, and a 

 conspicuous one with a hyaline centre close to the bifurcation of 

 the hind cubitus, and a smaller fuscous dot in the same position in 

 the hinder wing, but as the bifurcation is there shorter the dot is 

 nearer the base ; all the nervures and nervules are whitish 

 flavescent, interrupted by fuscous bands, and all bristling with 

 fuscous and flavescent stiff hairs ; the femora are rufescent, the 

 tibiae sub-flavescent, and the tibial spurs are turned inwards, and 

 hooked almost at right angles at apex. 



Length of body (?), of foi'e wings expanded 102 mm., of hind wings 

 87 mm. 



This species is not unlike A. dasymalla, Gerst, but the neuration 

 of the wings is more flavescent, the fuscous markings are quite 

 different, and the shape of the spurs differs greatly.

J' . Colouring and vestiture of A. mashunensis differs, especially 

 by the colour pattern of the fore wings; all the nervures and 

 nervules are flavescent, and interrupted by longitudinal black bars ; 

 they are long, plainly sinuate in the lower margin at apex, and they 

 have no distinct trace of pterostigma ; the sub-costal and marginal 

 nervures are distinctly separated from the base to the position of the 

 stigma, the costal area has a single row of cells, of which three or 

 four become furcate near the apex of the sub-marginal costa, where 

 it unites with the radial, and along the centre of the wing runs a 

 narrow deep fuscous brown line, slightly sinuate at the end and 

 reaching from the base to a short distance from the apex ; legs 

 brownish red ; tarsal spurs long, the upper part bent at right angles, 

 forming thus a very sharp hook. 



Length of body 35 mm. ; of fore wings expanded 96 mm., of 

 hind wings 80 mm. 



Hab. The habitat of the single specimen in the Museum Col- 

 lection is not recorded, but I have seen another example from 

 Bechuanaland.
