134 THE entomologist's eecord. 



oval rim (transverse) on the posterior area of the segment, a little below 

 the middle. In the centre of the lateral area, above the spiracle, is a 

 single hair. Above the legs is a large tubercle with two hairs. At 

 the base of the legs are several hairs, but the first chitinous joint 

 appears to be destitute of hairs, whereas the remaining joints have 

 three or four hairs at the outer edge of each. The legs on each 

 thoracic segment are the same. 2Ieso- and Metathorax — I cannot find 

 hairs representative of trapezoidals, but there are, one above another, 

 two hairs ; these, with two single lateral hairs, form a disconnected 

 marginal series on the anterior edge of the segment. The lateral swell- 

 ings (? tubercles) consist of three principal and some minor raised areas ; 

 the upper (supraspiracular) swelling has two hairs, the middle is with- 

 out hairs, and the third corresponds with that above the legs on the 

 prothorax, and has two hairs ; there is also a small anterior interseg- 

 mental tubercle with one hair. Abdominal ser/ments. — All the hairs 

 seem to rise from simple rings, not from chitinous (?) areas, as in most 

 larvae with which I am acquainted, thus the su.bspiracular tubercles 

 (iv, v) can only be regarded as coalesced, in that they rise separately 

 from a common swelling (? segmental area, not tubercle) and not a 

 common chitinous base. On all the segments the trapezoidals are 

 reversed from the normal position, i.e., anterior remote and more 

 lateral, posterior close and more dorsal. The supraspiracular tubercle 

 has only one hair, though the ring or scar of a second hair is notice- 

 able. The spiracle is circular, and on the lower anterior area of the 

 supraspiracular swelling. Below is the subspiracvilar swelling with two 

 hairs, an anterior tubercle with one hair, and a subventral swelling 

 with two hairs on the 1st and 2nd abdominal segments. On 3, 4, 5, 

 6, the subventral swelling becomes a proleg (apparently two-jointed) 

 with two hairs at the base ; the tubercles on 7 and 8 are arranged as 

 on 1 and 2 ; on 9 the posterior trapezoidal and supraspiracular hairs 

 are on the posterior edge of the segment, as are the subspiracular, 

 which, however, still rise from a common swelling ; below these are 

 two single hairs. On 10, above the anal orifice at either side, are four 

 single hairs, two beloAV, and two at base of claspers. Ventral view. — 

 The arrangement of the hooks of claspers is a semi-circle on each, 

 incomplete on inside, consisting of one row of strong hooks only. On 

 the prolegs it is a transverse oval, incomplete on the inner side, a single 

 row of hooks, much stronger on the anterior side than they are on 

 posterior side of oval. At the base of each leg on thoracic segments, 

 is a single hair ; this also is present on all the abdominal segments. 

 Under a one-quarter inch objective the skin appears simply rough, 

 about as much so as an ordinary hen's egg. I could detect no trace of 

 minute hairs, such as are present on some larvae, but in the spaces 

 between the lateral swellings the skin has a very fine reticulation. —

Sesia cynipifokmis and S. culicifoemis near Croydon. — During 

 the past week I have taken about 50 full-fed larva of Sesia cynipiformis, 

 and during March about the same number of Sesia cidiciformis larvae. 

 Both insects are fairly common not far from Croydon. — Chas. B.
