line, the other near the wing-base. The metathorax is comparatively 

 small, has fewer and very large punctures, and two bristles, as in 

 mesothorax ; the posterior wing stretches down in a narrow strip 

 vanishing abovit middle of 4th abdominal. 



The 1st abdominal segment is small, has pits about the same in 

 size and distribution as on metathorax ; these continue on all the 

 following segments, but get gradually smaller, though not very 

 materially. On ten they ai-e absent. Ou one (abdominal) there is 

 only one bristle (i.), the site of ill. being beneath hindwing. On 

 2-8 (abdominal) are two bristles (i. and iii.), No. ii. being absent ; on 

 9 is one dorsal bristle (iii. ?). The spiracles of 2nd and 3rd abdominal 

 have the common appearance of having been shoved back by the 

 wing, and of having pushed a ridge of chitin before them. The 

 remaining spiracles are inconspicuous, rather large, with sharj) 

 raised margins. Ventrally (4-9) the pits are fewer and smaller. 

 On 5, 6 and 7 only a subspiracular bristle exists ventrally, but 

 there are two on 8 and 9. The anal armature consists of a trans- 

 verse row of four blunt pyramids, two on either side, each carrying 

 a spine, and two similar projections with spines, further out and 

 rather dorsal. These spines are 0"13 m.m. long, and terminate in a 

 coil, forming a complete circle, so that if straightened out they might 

 be about 0'2 m.m. in length.
