236 CHAS. K. BRAIN. 



Male puparium white, moderately elongate, usually with a prominent median 

 ridge and two lateral ones, which are especially conspicuous at the posterior end. 

 Exuviae pale, yellowish or almost colourless. 



Adult $ (mounted) about 1'6 mm. long, widest (0"7 mm.) some distance behind 

 the middle ; abdominal segments not produced but distinctly indicated at the margin ; 

 body not noticeably chitinised. The median notch is wide, with two short plates 

 and two short spines. L L wider than long, uniformly rounded when not worn ; L 2 

 composed of two lobules, which may be somewhat rounded, but most often pointed. 

 Beyond these there is a plate, then two or three angular projections from the margin, 

 a short spine and a plate. Each segment is indicated rather sharply by the hind 

 angle being slightly produced. The last row of dorsal glands is interrupted near 

 the margin and is somewhat doubled, 3 to 4 pores lying inside, and 2 or 3 outside ; 

 the main series, which comprises 6 or 7 pores, does not reach so far back as the anus.

Adult $ broadly oval, with the two extremities about equally rounded, thin, 

 hyaline, with the posterior margin exhibiting a series of rounded projections. 

 The largest represent the margins of the three abdominal segments, the remainder 

 of the pygidium consisting of smaller round projections. No lobes. The position 

 usually occupied by the median lobes is slightly recessed and bears two short 

 plates. On each side of this there are two gland openings followed by a flatly rounded 

 protuberance, then two more gland openings, another protuberance, two more glands 

 and a rounded protuberance which terminates at the junction of the last free 

 abdominal segment (fig. 155). Parastigmatic glands present, 4 to 5 at anterior 

 spiracles. Circumgenital glands in 5 groups : —
