[Read 3rd December, 1866.] 
HEMEROPIDZ. 
RaprisMA, n. g. 
Caput sub prothorace occultum ; oculi globosi, parvi; antenne 
breves, intus sub-serrate, pilose; palpi parvi. Thorax et 
abdomen valde robusti; prothorace late transverso. Pedes 
breves, pilosi. d/@ ample: antice sub-coriacee, pilose, 
elongate, latee, sub-acuta, margine apicali obliquo; spatium 
costale basi latissimum, venulis transversalibus numerosis, 
furcatis, areolis numerosis (ad basin seriebus 3-5 dispositis) 
irregularibus; sub-costa a radio separata, spatio sub-costali 
venulis transversalibus numerosis instructo; sector primus 
radio parallelus, sectores ceeteros emittens ; venule gradate 
per-numerose, membranam in cellulis parvis dividentes : 
postice anticis breviores, sub-hyalinze ; spatium costale an- 
gustum ; vene fere ut in anticis. 
Type.—Hemerobius viridipennis, Walker, Cat. Neurop. Brit. 
Mus. pt. 2, p. 276, 1; from the East Indies. 
A very remarkable genus of Hemerobide, on account of its 
robust body, large size and subcoriaceous anterior wings. It 
bears some resemblance to Jthone (incorrectly placed by New- 
man and Walker in the Sialide), but differs in the breadth of the 
basal portion of the costal area, in the absence of a recurrent 
veinlet, in the details of neuration, and in the head, which is so 
much retracted under the prothorax that the front alone is visible ; 
it is probable that the living insect has the power of extending 
the head, but in dead examples it is so greatly concealed, that 
but for the antennz and eyes, it would be scarcely seen at all.
