by the anal clasyjers, and, hanging with its head downwards, 

 is transformed into a short and very obese pupa, the head of 

 which is rounded and undivided ; the anal extremity, tliat is, 

 the 13th segment only, very attenuated and flattened, the ex- 

 treme tip still narrower, slightly incurved, and terminating in 

 a row of minute hooks, by means of which it adheres to a 

 slight web which the larva had previously spun, and from 

 which it had suspended itself. The colour of the pupa is 

 pale wainscot-brown, with a semitransparent appearance in 

 the wing-cases, which, as well as the antenna), are delicately 

 clouded and reticulated with darker brown ; the dorsal 

 surface is also delicately dotted with brown, as well as 

 having larger spots methodically arranged ; a pair of these, 

 transversely elongate, but arranged longitudinally, form an 

 almost medio-dorsal series on each side of each segment. 

 The butterflies continue to emerge from the 1st of July to 

 the end of the month, and also in the first and second weeks 

 in August. I am indebted to Mr. Doubleday for the larva 

 and pupa from which my description has been made. —

Description of the Larva of Chortohius Davus (Marsh 

 Ringlet).— The egg is laid in July, on the setiform leaves of 

 Rhynchospora alba (beak-rush), and the larva emerges in four- 

 teen days or less, according to the temperature. Head semi- 

 globose, wider than the body, slightly notched on the crown, 

 beset with minute hairs ; body linear, its sides almost paral- 

 lel, but slightly and gradually attenuated towards the anal 

 extremity, which terminates in two points directed back- 

 wards ; dorsal surface transversely and regularly wrinkled, 

 the wrinkles dividing each segment into sections, and co- 

 vered with minute warts, which under a lens give the surface 

 the appearance of extremely fine shagreen. Colour of the 

 head dingy semitransparent green ; the ocelli very prominent 

 and intensely black : colour of the body dingy green, with 

 five narrow, equidistant, distinct, purple-brown stripes ; the 

 interspace between the 2nd and 3rd stripe on each side is 

 intersected by a very narrow and indistinct stripe, almost 

 similar in colour to the other five, and the exterior purple 

 stripe on each side is bordered below by a pale glaucous, 

 almost white, stripe, extending throughout its entire length. 

 At the end of August these little larvae ceased to eat, and
