latter part of April or the beginning of May, and become 

 images in June. The larva is dirty whitish in colour, with 

 a brown head and shield and scarcely one-half an inch long ; 

 the larger larva is quite an inch in length, with no distinctive 

 markings. Pruniramiella makes its cocoon of " frass" and 

 silk in a gallery formed in the wood, but near the surface. 

 The pupa has minute spines on the dorsum and is thrust 

 from the cocoon at maturity. 



The following species, I believe, forms a new genus. It 

 is rather rare, at least I have met with the imago but few 

 times. I know nothing of its embryonic states. In appear- 

 ance the imago bears considerable resemblance to the figures 

 of Euplocamus Boleti of Europe, but its generic characters 

 separate it from the latter very distinctly. 



AMYDRIA. 



Head free, as broad as the thorax, roughly haired (the 

 hairs of the front ascending and those of the vertex inclined 

 from each side towards the median line, or having a stelliform 

 arrangement behind the antennae). Ocelli none. Eyes small, 

 hemispherical and salient. Antennas simple in both sexes, 

 moderately thick, with joints closely set and with whorls of 

 scales, one-half as long as the fore-wings and scarcely two- 

 thirds as long as the body. Maxillary palpi extremely small 

 and two-jointed. Labial palpi with the second article beneath 

 hairy and formed like a brush ; the third slender and ascending. 

 Tongue wanting. Wings narrow, much exceeding the tip 

 of the abdomen ; the anterior elliptical, cilia rather long, 

 especially at the inner angle, giving the wing the appear- 

 ance of being angulated; posterior obtusely ovate, with 

 moderately long cilia behind. 



A. effrenatella.* Labial palpi yellowish-brown, with the 



* This is printed effrentella, but Dr. Clemens has written in pencil that an 

 a should be inserted between the n and the t. I received one specimen of this 

 insect ; it is probably an Euplocamus ; in the structure of the palpi it comes 

 very near to E. tes&ulatella. (See ante, p. 39.) H. T. S.
