NO. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE <£ BAKER. 349 



and each of the larger ones has near its distal extremity a peculiar 

 notch-shaped structure (fig. 4). There are also on the dorsum five 

 pairs of setae — one pair on the caudal extremity, one pair just 

 cephalad of the vasif orm orifice, two pairs on the median dorsal portion 

 of the thorax, and one pair, more widely separated, on the cephafic 

 margin of case. Vasiform orifice (fig. 3) subcircular, with the oper- 

 culum almost entirely filling the orifice and obscuring all but the tip 

 of the lingula; margin armed with moderately rounded teeth. 



Pupa case (fig. 1). — Length 1.168 mm.; width 0.75 mm.; shape 

 elKptical, with a moderate median ridge. The type-specimen is 

 much broken and so poorly preserved that it is difficult to make out 

 the dorsal structures; color very dark brown; submarginal area 

 with about 22 prominent spines forming a ring. These extend well 

 beyond the margin, are acute at the tip, and each is armed a short 

 distance from its distal extremity with the same peculiar notch-hke 

 structure found in the larva (fig. 4). The caudal pair of these 

 spines is broken off from the type-specimen, but we have figured them 

 longer than the others as described by Maskell. Just below this 

 submarginal row of spines there is a row all around of very many 

 mmute, knobbed setae (fig. 5). These are very small, being no 

 longer than the spines are thick at their bases. Each of these httle 

 setae has the knob and the distal half transparent, while the basal 

 half is dark brown. The dorsum is armed with a number of spines, 

 but owing to the very poor condition of the type it is impossible to 

 say with certainty either the number or the position of these. As 

 near as we can make out, however, they are shown in the illustration. 

 The submarginal area is irregularly pigmented, giving a very distinct 

 mottled appearance. The margin is dentate with the teeth moder- 

 ately acute and the interspaces shallow. A space of 0.1 mm. is 

 occupied by about 16 teeth (fig. 2). 



Habitat. — Ceylon on Piper nigrum ( ?) . 



Since the foregoing descriptive notes were made we have received 

 from Mr. Andrew Rutherford a slide marked "Peradeniya 9-8-13." 

 This shde contains a pupa case which is no doubt piperis. It has the 

 same knobbed setae, the same notched spines, and the same general 

 characters. The caudal spines are, however, not longer than the 

 others as described by Maskell, but are about the same, length. 

 The caudal setae are long, about two-thirds as long as the caudal 

 spines. In the character of the notched spines this species is similar 

 to citriperdus. 



ALEUROCANTHUS SERRATUS, new species.

This species occurs in two lots of material collected on an unknown 

 tree in the Botanical Gardens, Buitenzorg, Java, by R. S. Woglum
