C) Mr. R. Trimen on Larvae of Hamanumida daedalus, 



Larva. (Description of specimen preserved in formalin) 

 P]. I, figs. 2b, 2c. 



Total length 3 in. 



Head large, rounded ; about 3 lin. both in vertical and transverse 

 diameters. 



First thoracic segment not much larger than head, superiorly 

 flattened almost horizontally but forming ]a slight elevated ridge 

 immediately behind head ; second segment considerably and third 

 very much larger than head. 



Abdominal segments 1-3 all larger and thicker than thoracic 

 ones, and also than the three next succeeding abdominal ones ; — the 

 first abdominal segment witli a moderate median conical dorsal 

 elevation, surmounted by a small smooth mammillated wart. Ab- 

 dominal segments 7-9 greatly modified in form, being not only 

 larger and thicker than the three next preceding ones, but having 

 their lateral margins widely produced so as to constitute a large 

 common ex2oansion, more than 1 in. long and nearly | in. broad in 

 widest part, thinning off to a leaf-like edge. No anal pro-legs, but 

 possible rudiments of them in the shape of two very small minutely 

 granulated ferruginous ridges. On flattened ventral surface this 

 unified group of the last three segments presents the appearance of 

 a sub-ovate acuminate leaf with irregularly flexed and sinuated 

 margins, a median elevated longitudinal stripe of paler tint repre- 

 senting the midrib, and six pairs of slightly depressed transverse 

 streaks, together with two similar basal but longitudinal ones, the 

 branching veins ; the wliole surface being moreover finely pitted in 

 resemblance to the stomata of a leaf. The humped back of the 8th 

 segment bears at apex tliree minute mammillated warts, and the 

 extremity of the anal segment two more prominent and acute warts. 



General colour throughout a bright pale yellowish-green, appar- 

 ently without markings.* Head brownish-red, widely reticulated 

 with ferruginous lines ; mandibles reddish-yellow with conspicuous 

 black extremities. Legs reddish-yellow with rusty-black terminal 

 claw ; pro-legs mixed greenish and ferruginous. On almost hori- 

 zontal ridged front of first thoracic segment, immediately above 

 head, two widely-apart elevated ferruginous sjjots, in position and 



* This is the case in the specimen under description, but in Mr. 

 Millar's photographs of the living larva there appears a general 

 close minute speckling of paler dots on a darker ground (looking not 

 unlike the granulation in /S'lnerinthus larvae) ; and there is also, in 

 the photographs which show a considerable part of the dorsal aspect, 

 a very distinct and broad pale longitudinal median band beginning 

 on second abdominal segment. Possibly the jjhotogi'aphs represent a 

 larva not in tlie final moult. See PI. I, figs. 2d, 2e.
