are also decorated with black markings, which are perceptible 

 when the larva is at rest, and become conspicuous when it is 

 crawling. The ventral surface is ornamented with black 

 spots, but has no yellow ones; the 5th and 6th segments 

 have each eight such spots, the others much fewer ; the legs 

 are yellow ; the ventral claspers are yellow at the extremities, 

 and each has several black markings, more particularly a large 

 one in front ; the anal claspers are yellow at the extremity, 

 and have four black spots, on the outside of which the 

 anterior is large and pyriform ; every black spot, whether on 

 the head or body, emits a black hair, a circumstance sugges- 

 tive of some physiological connexion between the two ; I 

 find no other hairs than these on any part of the body. —

Description of the Larva of Ennomos tiliaria. — Rests in 

 a very stiff and stick-like position, with the claspers firmly 

 attached to the twigs of Betula alba (birch), on which 

 it feeds : the head is porrected on the same plane as the 2nd 

 and 3rd segments ; the legs are directed forwards, the second 

 and third pairs being closely appressed to the pectoral 

 surface of those segments : the head is nearly equal in width 

 to the 2nd segment, the face flat, and the anterior margin 

 squarely truncate : the body gradually increases in size from 

 the head to the 12th segment, which is slightly the stoutest 

 of the whole; the 4th segment, bearing the third pair of legs, 

 is somewhat produced on the ventral surface, and the legs 

 are seated on the elevation ; their form is a crescentic curve, 

 and their direction forwards; the 5th, 6th, 7th, 8th and 9lh 

 segments are long in proportion to the width ; the 6th and 

 9th have transverse dorsal ridges, that on the 6th segment 

 being decidedly the larger of the two : the 7th segment has 

 a transverse ventral series of four lumps or warts, each wart 

 being transversely elongate. The colour of the head and 

 body is gray and brown, except the ventral surface of the 

 12th and 13th segments, which is glaucous-green. The 13Lh 

 segment terminates in three points directed backwards ; the 

 middle one of these is very much smaller than the others. 

 These larvae, for an am]de supply of which I am indebted to 

 Mr. Birchall, changed to chrysalids about the 16th of July, 

 and to moths on the 1st of August. — Id.
