[November, 



Luxemburg ; and once witli L. fluvus (without li. europcca), Linz 

 (Rhinelantl)." Wasmanii Coll. 



Although Father Wasmann has found this species associated with 

 Bipersia europcea, Newst. [Ent. Mo. Mag. (2), vol. viii, p. 167, 1897], 

 it is quite distinct from the latter in the form of the antennae, and the 

 position of the anal lobes ; furthermore, Father Wasmann informs 

 me the colour of B. europcea is yellow. 



Lecanium, sp. ?. 



Hah. : " Matheran, N. Konkan, sent without ants — probably with 

 same Crcmaslogastcr as Dactylopiusformicarius''' (Wasmann) . Wrough- 

 ton Coll. 



A number of specimens were sent attached to the roots (?) of an 

 unknown plant. In all probability the species is a new one, but the 

 specimens are very small, and probably immature. In the absence of 

 more reliable information I must withhold the description of the 

 species ; meanwhile trusting Mr. Wroughton will give the matter his 

 further attention. 



PERISSOPNEUMON, n. gen. 



9 adult possessiiig both marginal and ventral spiracles ; anal, dorsal, and 

 ventral openings, and above the latter a pouch-shaped cavity. Antennee, legs, and 

 rostrum present. 



Perissopneumon eerox, n. sp. 



y adult elongate, longitudinally and transversely convex ; 

 segmentation distinct ; legs, antennsE, rostrum, and ventral orifice 

 piceous. Antennae strong, and highly chitinised, of 8 joints (fig. 

 4), tapering from base to tip, basal and terminal joints longest, 

 SliZ'^ formula (1,8) (2,3) (4,5,6,7), all with numerous fine hairs. 

 Eyes ventral and near the insertion of the antennse. Legs much 

 stouter and longer than the antenna), sparsely clad with hairs ; 

 claws stout and simple; digitules to claw fine simple hairs. 

 Mentum biarticulate ; filaments short. Dermis (fig. 5) almost 

 covered with short stiff hairs, interspersed with large, irregular, 

 ovate glands (a), with an opening towards the widest end. 



Spiracles on the ventral surface (fig. 7) four 



in number ; those at the margin on the dorsal 



surface fourteen in number, seven on either 



side of the abdomen, and are of the form shown 



at fig. 56, figs. 6 and 8 ; the exterior portion 



cylindrical, with the sides covered with circular 



spineretts. Between the spiracles are large, 



clear, roughly crescent-shaped, valve-like 



organs (fig. 5c), and grouped glands (fig. bd). 



Anal ring (fig. 9) without hairs, but a double 



series of circular spinnerets.
