Thecla grunus, Boisd. 



Larva. — Head testaceous, with a black shade on each side ; width, 

 1.2 mm. Retracted beneath joint 2. Body flattened, tapering some- 

 what posteriorly but rounded, the segments arched. A subdorsal and 

 subventral ridge, not very prominent. Dark or bluish-green, without 

 white granulations, but having minute, brownish, piliferous dots, quite 

 densely distributed. Obscure geminate dorsal, single subdorsal, stigma- 

 tal and subventral lines, pale whitish and broken, becoming later yellowish, 

 and the subdorsal one distinct and almost continuous. The two subdorsal 

 lines are 2.2 mm. apart. The pile on the body is longer and stiffer on 

 the subventral ridge than elsewhere. A rounded, diamond-shaped, 

 depressed, cervical shield situated about the centre of joint 2, on which 

 the blackish, elevated, piliferoils dots are smaller than elsewhere. 



Chrysalis. — Suspended by the cremaster and a loop of silk. Short, 

 thick, flat on the ventral side, rounded dorsally, with a very slight depres- 

 sion between the thorax and abdomen. Colour pale green, speckled with 

 blackish (but faintly); a bright yellowish subdorsal line on the abdomen, 

 faintly continued on the thorax, and a double dorsal row of yellowish dots 

 on the abdomen.

Crambus albiliueellus, n. sp. 



Expanse of wings, 26 mm. Head, palpi, thorax and fore wings dull 

 ochre-yellow. The palpi are darker on the outside, and the subcostal, 

 median and veins 5 to 10 are white. A stripe of lead coloured scales 

 extends from the base of the wing just above and parallel to vein 1 to the 

 outer cross line, and a similar stripe occurs between this and the hind 

 margin. Two lines cross the wing : The first is dark brown, and arising 

 from a point a little before the middle of the costa forms an outward 

 angle very near the costa and an inward angle on the subcostal vein, then 

 a second outward angle is formed at the end of the median vein and from 

 this point the line runs more or less distinctly across to the middle of the 

 hind margin. The second line is dark brown but finer, dentate and edged 

 on the outside with lead coloured scales, and runs from the costa before
