visible, with apparently some room for movement in the cavity 

 thus formed. 



" Each jaw carries three teeth, not mere notches as in Lepi- 

 doptera generally, but each tooth is a long sharp spine, capable of 

 piercing, but certainly not of biting ; each jaw is probably capable 

 of meeting the other so that the teeth may interlock, but in the 

 specimens examined one jaw is entirely in front of the other.

" Not so remarkable as a structural modification, but more so 

 perhaps as connected with most unusual habits, is the modification 

 of the jaw r s as piercing and tearing and no longer biting organs ; 

 and if I observe correctly, the alterations of the fcrophi into a 

 suctorial tube, from which the jaws are just able to protrude is 

 remarkably similar, functionally, to the tube surrounding the jaws 

 in Phyllocnistis, though the details of structure and habits are so 

 widely different. 



" The jaws would most effectively take hold of the skin of an 

 ant larva, piercing its skin at the same time in six places ; they 

 would then draw the piece so seized within the closed cavity 

 formed between the labrum, labium and (laterally) maxillae so 

 that the juices of the larva could be easily sucked out." (T. A. 

 Chapman, I. c.) 



Pupa. "The pupa I have before me is very large, 28 mm. long, 

 14 mm. broad, and 10 mm. deep, whilst it is depressed in 

 front in a way apparently due to pressure ; were the rounded 

 contour of the dorsum and sides continued its depth would 

 be 12 mm. It is typically Lycsenid in form, being very round 

 at either end, broadest at fourth and 

 fifth abdominal segments, narrower 

 thoracically ; head beneath ; no move- 

 able segments ; no trace of crema- 

 sternal hooks or of any silken girth : 

 first leg equally against head and 

 antennae. The maxillae are well deve- 

 loped ; they appear to contain no 

 maxilla (? palpus), the specimen being 

 close on emergence, but the labial 

 " )i are very evident between them.

Larvarcase with pupa inside. i s a set o f flanges or raised ribs. 

 If the pupa was divided into a dorsal 



and ventral piece by a section through its widest dimensions, 

 the line of section would mark one of these ribs, which starts 

 round the abdominal segments from the anal angle of the wings 

 (end of vein 1 c) and goes round the end of the pupa dividing 

 the last segment into two portions ; this segment is conse- 

 quently of considerable antero-posterior dimensions, stretching 

 a good way under the pupa but always having a portion as it 

 were lifted right out on to the dorsum by having to be above the 

 flange. The segmental incisions are all raised into double ridges,
