^ has 7, others have 7 joints, with a sort of scape as in the Hymenop- 

 tera, and the tibia and tarsus in one, and the adult ? has 8 joints in the 

 antennae. No species of this genus has as yet been recorded from 

 India ; it is described by Signoret [A. S. E. F. (5 ser.) v, p. 386, 1875] 

 and Douglas [Ent. Mon. Mag. xvii, p. 172, 203, L881] and need not be 

 further noticed here.

$ . Antennae with ten short joints, 2 and 10 of equal length and 

 longest : body in its normal state covered with a great number of yellow 

 hairs mingled with a white, calcareous, lamellar secretion which, when 

 removed, shows the body to be like that of a $ of the genus Monophle- 

 hus. The skin has rows of spinnerets differing as they produce the 

 pilose or calcareous secretion : feet robust, of moderate length and of 

 the usual appearance ; claw stout, with a hair on each face ; the tarsi 

 one-third as long as the tibiae which latter are longer than the femora. 

 At the anal extremity before the margin, the genital ring is surrounded 

 by a great mass of large hairs : above on the penultimate segment, are 

 three cicatrices, of which the median is transverse, roundly oval, and the 

 lateral are longitudinal oval.

Dark red, elliptical, white above, with a double row of lateral, 

 truncated, yellowish- white, elongated appendages, and with some silky 

 hairs : forepart with some dorsal porrect appendages of the same shape 

 (Walker). Long 6 — 7 millims. 



Signoret (1. c.) describes the adult 9 as forming a many coloured 

 pilose mass, yellow, more or less light, more or less tawny, with white 

 calcareous plates strewn regularly over the upper surface and on the 

 sides of the abdomen : the yellow pubescence is longest and most 

 abundant on the thorax, especially on the median line, which causes 

 the white secretion to be less visible : beneath, the entire body is en- 

 tirely margined with white plates : abdomen with a slight white efflo- 

 rescence ; segments visible and each more and more emarginate as they 

 approach the tip, the median part of the last segment reascending as 

 far as the basal third of the abdomen with the anal or genital opening, 

 around which is a considerable mass of long hairs. Antennae blackish, 

 with ten joints of which the first is siout and short, the second and tenth 

 are longest ; at the tip of each joint is a circlet of short hairs and there
