CYCLOPIDIItl. 191 



Cyclopididi have a great range in the Palaearctic and Nearctic areas. 

 The family is diagnosed under the name Pamphilinae, Sect. A, by 

 Watson (Proc. Zool. Soc. Land., 1893, p. 69), as follows : — 



Antennae very varied, never much hooked, and usually sharply pointed. [In 

 all the genera, in which the tip of the antennae is blunt, the epiphysis on the fore tibiae is 

 wanting, excepting in one or two Australian forms.] The palpi have the third joint 

 usually" short and inconspicuous, in some few genera long and slender, in these it 

 is always erect and never porrected horizontally in front of the face. Forewing 

 with cell always less than two-thirds the length of costa ; nervure 5 slightly 

 nearer to -1 than to 6, except in some aberrant Australian forms, in which it 

 is slightly nearer to 6. Hindwing never with a conspicuous tail or tooth, though 

 frequently more or less lobate ; nervure 5, never well developed. 



Subfamily: Cyclopidin^:. 



Tribe : Cyclopididi. 



The tribe containing our representative Palaearctic genera 

 (Heteropterus and Cyclopides) is tabulated by Watson as follows :■ — 



a. Vein 5 of forewing not nearer to 6 than to 4, usually distinctly nearer to 4 

 than to 6. 

 b. Xo epiphysis on fore tibiae. 



c. Antennae, short, less than half the length of the costa. 

 d. Vein 11 of forewing free. 



e. Club of antenna arcuate, tip acuminate — Eumesia, Feld. 

 (Type semiargentea, Feld.) 

 -» e\. Club of antenna straight, tip blunt. 



/. Vein 3 of forewing well before end of cell ; vein 

 2 nearer to base of wing than to end of cell — 

 Heteeopteeus, Dum. (Type morpheus, Pall.) 

 /i. Vein 3 of forewing innnediately before end of cell ; 

 vein 2 nearer to end of cell than to base of wing 

 — Cyclopides, Fabr. (Type palaemon, Pall.) 

 d\. Vein 11 of forewing running into 12 — [Watsoyia nov. gen.] 

 (Type metis, Linn.) 

 The tribe is noted by Speyer (Can. Ent., x., p. 150) as being 

 characterised, so far as the Palaearctic genera are concerned, as 

 folio ws : — 



The tibial epiphysis of the front legs wanting. Club of antenna elongate-oval, 

 terminating conically, slightly curved. Apical joint of palpi conical, projecting, 

 almost horizontal. Tibiae armed with spines, at least the middle ones. Abdomen 

 longer than the head and thorax united, the posterior wings uplifted. Male without 

 the costal fold, the stigma, and the tuft on the tibiae. 



In our preceding larval descriptions, we bave frequently referred to 

 the peculiar structures called " lenticles," which are found in this stage 

 in the Urbicolids. As it was in mandan, one of the American forms of 

 C. palaemon, that these were first noticed, we may here add 

 Fletcher's remarks thereon. He notes [Can. Ent., xxi., p. 115) them 

 as small rounded chitinous disks, which appear to be trichouies or 

 modified hairs, an opinion formed on the fact that, in one species 

 (observed later), there occurred in two instances, instead of these disks, 

 piliferous tubercles ; he adds that they are small and difficult to examine; in 

 C. mandan they appear to be saucer-shaped, having a raised edge ; in a 

 species of Pamphila (near manitoba), they are, in some instances, simple 

 annuli, but, in P. cemes and P. mystic, seem to be rather cone-bhaped. 

 Similar lenticles were observed on the pupa of P. cemes.
