the Larva and Pupa of the Genus Sabatinca. 445 



ridging is changed into a series of reniform marks of very minute 

 size, arranged in a more definite order parallel to the margin of the 

 segment. 



On the first six abdominal segments, arranged close together on 

 either side of the mid-dorsal line, there are to be seen a pair of small, 

 hard ridges of a very dark colour, each ridge carrying four or five 

 short blunt teeth (Text-fig. 1, h). These I propose to call the dorsal 

 combs. They are arranged longitudinally, and each pair lies close 

 to the posterior end of its segment. Thus they occupy much the 

 same position as the paired annulated dorsal tubercles in the larvae 

 of Mecoptera. 



Descri])fion of the Pupa and Cocoon of Sabatinca incongruella 



Walk. 



(Text-figs. 2—4) 



CocooK : — ^The cocoon of Sabatinca incongruella is of a broadly 

 oval shape (Text-fig. 2), 3-0 mm. long, with a transverse diameter, 

 across the middle, of 2-3 mm. The posterior end is very slightly 

 pointed. In colour it is a medium brown. It is foi med of rather 

 coarse silk, and has a somewhat leathery appearance. It was 

 found attached by its slightly pointed posterior end to the stem of 

 a piece of liverwort, the cocoon itself projecting nearly at right 

 angles, but slightly inclined do-miwards from the stem. The pupa 

 had cut open the anterior end somewhat roughly, and the pupal 

 skin was found projecting more than half-way out of the cocoon. 



Pupa : — A careful examination of the macerated pupal skin shows 

 that the pupa must be rather stout, not much elongated, with a 

 general shape very closely resembling that of the Hemerobiidae and 

 other small Lacewings. 



The abdomen is broadly oval in shape, convex dorsally, with the 

 last two segments somewhat bent under ventrally and the thorax 

 also curved forward somewhat ventrally. The head is bent forward 

 ventrally, so that the whole pupa has a strongly curved position 

 within the cocoon. 



Head (Text-fig. 3, a) fairly broad, with convex epicranium. 

 Antennae with very large basal segment ; second segment about 

 three-fifths as long, narrower; remaining segments narrower still 

 and very short, all closely similar; total number of segments 

 thirty-seven. Compound eyes large, separated by a space some- 

 what wider than their diameter. Epicranium, frons and clypeus 

 carrying a few very long, slender hairs; a set of three such hairs 

 stands behind each eye.
