in the mid-dorsal area the circular arrangement so conspicuous a 

 part of the pore design in some other species; quinquelocular disk 

 pores present in four heavy bands between spiracles and margin, as 

 already described, in small clusters near antennae and scattered 

 widely over the ventral body surface; multilocular disk pores, usually 

 with multiloculate centers present anterior to the genital opening in 

 at least two or three transverse segmental rows of widely separated 

 pores, each row ending in a small cluster of pores; tubular ducts 

 quite numerous, but slender and not at all conspicuous; cribriform 

 plates in two clusters only, each including two or, less frequently, 

 three small, roughly circular plates, each set in protruding chitinized 

 rim ; no tiny simple pores observed ; anal lobes well developed, taper- 

 ing, often obscured through the retraction of the extreme apex of 

 the body, the ventral and inner faces more or less chitinized, this area 

 on the inner face large areolate, apical seta rather stout, about 150/i 

 long, the two stout curved setae on upper face fairly elongate, about 

 •36/i; Cauda tapering rather strongly, about 55jli long by 70/^ wide, 

 apex rounded ; anal ring with a single row of pores and eight setae, 

 each about 83/x long. 



Intermediate female. — Not available. 



Larva. — Very similar to this stage of other species; length as 

 mounted about 420ju, width about 200/1,; antennae 6-segmented, the 

 third longest; legs not unusual; beak short conical, fairly distinctly 

 2-segmented; marginal setae small, slender; no spiracular spines; 

 8-shaped pores large, in the usual two complete and one incomplete 

 rows on each half of the dorsal surface; apical setae of the slightly 

 protruding anal lobes about 215/x long, cauda fairly strongly pro- 

 truding, with rounded posterior margin; anal ring wdth a single 

 row of pores and six setae, each about 32/x long. 



Specimens of the species auranticus Froggatt, sent by Mr. Frog- 

 gatt to the United States Bureau of Entomology, have been compared 

 with slides of Maskell's paradoxus., but no basis for separating the 

 two on morphological characters has been discovered and they are 

 here regarded as identical. 



It should be noted that no original actual type Maskell slides 

 were represented in the collection and there is therefore no absolute 

 assurance that specimens from the type material have been examined 

 at all. From his description and from other circumstances it seems 

 reasonably certain that the species redescribed here is actually the 

 fa/radoxus of Maskell. 



The closest relative is the species punctvliferus Green, found on 

 the same plant host. The two apparently differ in one respect only : 

 in paradoxus the larger sized 8-shaped pores are confined to the sides 

 of the protruding caudal portion of the abdomen and to clusters on 

 each side of the four spiracular pore bands, with an occasional large
