A NEW PHALACROPTKRYGID SPECIES AND (JENUS FROM SPAIN. 327 



behind it are a few parallel ridges, already indicated in the 5th, on 

 the 3rd this decadence progresses, and on the 2nd the roll is now an 

 area a little more marked than the following ridges, and with some 

 blurred points that hardly suggest hooks. The intersegmental re- 

 curved hooks are well developed on the 4th, 5th and 6th abdominal 

 segments, as a row of strongish hooks, or rather two or three rows, 

 but so far alternating as not to be one in front of another. On the 

 3rd they are represented by a double row of raised points. The 

 wings extend to the end of the 3rd abdominal. The dorsal slit on 

 dehiscence just fails to reach the posterior margin of the mesothorax. On 

 the metathorax there is a dorsal ridge and folds pass outwards to the 

 wider part of the segment, in doing so they open and pass round a space 

 somewhat hollowed, in which is a small cone, surmounted by a hair 

 (probably tubercle ii). On the other segments the larval tubercles are 

 apparently represented by hairs, but all are not made out, the specimen 

 not being mounted transparently. There is the usual pair of anal 

 hooks, immediately behind the genital tubercles. Unfortunately I 

 managed to lose the loose face-piece, so cannot describe the appendage- 

 cases. $ . One of the $ cases contained a pupa-case, containing the 

 remains of a 5 moth and some young larv^, dead. The ? pupa- 

 case is of the usual chitinous brown, paler towards the head, 10mm. 

 long and 3-5mm. wide at frds from the anterior end, about the 3rd 

 or -ith abdominal segment, it is, in fact, of the shape of an egg, the 

 posterior being the thick end. There are no legs, wings, etc., their 

 only representatives being very slight roughnesses of the front of the 

 anterior end. By careful examination these are found to represent three 

 pairs of legs and some mouth-parts. On the 7th and 8th abdominals 

 there are dorsally small patches of backward-directed spines, and some 

 also on 6th and 5th that would not be noted but by having first 

 observed 7th and 8th. The dorsal suture splits down to the thoraco- 

 abdominal incision. There is a minute double anal spine. The scars 

 of prolegs are obvious flat circles with concentric rugie. The hairs 

 of the larva are exactly repeated on the abdominal segments of the 

 pupa, even to the three pairs of minute secondary hairs. 



OvuRi. — The egg has no discoverable sculpturing, is oval in outline, 

 in fact egg-shaped, narrowing like an ordinary egg, a big end and a 

 little one, but the diti'erence is slight. There is also some difference 

 in form, some being shorter and wider, «.t;., more spherical than others. 

 The length varies from 0*8lmm. to 0-87mm., and the width from 

 0-63mm. to 0-70mm. They are laid in the pupa-case, amongst a 

 liberal supply of wool or hairs, and the female dies within the case in 

 front of them. 



Larva. — The young larva has black head, and black thoracic plates 

 and anal plates, like the fullgrown one. There is no trace of the 

 false tubercle i, tubercle i being in its usual (Macro-psychid) position, 

 far outside ii. Below the spiracle are two hairs, near together, and on 

 a level, the posterior the stronger ; there are two at base of prolegs 

 which have 10-12 hooks. No hair between these is made out. The 

 (? case that did not produce a moth showed, when opened, the remains 

 of a larva, and of the pupa-cases of several large chalcids. From 

 this imperfect specimen it appears that the head is black, as well as 

 the first three segments, at least, the 1st and 2nd thoracic segments are 

 covered dorsally by complete black plates, with no pale markings
