4 NEUROPTERA. 
latter pale. Fore femur pitch-brown ; tibia more translucent, in some lights sepia-grey; tarsus dull 
whitish. Wings as in 9. 
Length of wing, ¢ 26, 9 23-27; median seta broken off in the largest 2 specimen at 48 millim, 
Hab. Mexico, Vera Cruz (Sallé?, in Mus. de Selys-Longchamps'*); Guatemata, 
Aceytuno 5100 feet (Salvin), San Isidro 1600 feet (Champion) ; Panama, Volcan de 
Chiriqui (Champion), Veraguas (Mus. McLachlan ®). 
The male is described now for the first time, from two specimens obtained on the 
Volcan de Chiriqui, which match well with a female from San Isidro. Two females 
of similar dimensions, from Aceytuno, may have been subjected to the action of some 
poison or preservative ; they have the wings paler, for the most part less rosy and 
rather dirty; their meso- and metanotum are more distinctly luteous, but this may be 
due to the infiltration of shellac, which seems to have been used in attaching them to 
the pins. The smallest female is from Chiriqui; it has the wings tinted with rosy- 
grey, rather more strongly than those of the males from the same locality, or than 
those of the female from San Isidro; its eggs are retained, and the venter is yellow 
longitudinally in the middle and brown at the sides. The ¢ forceps of the specimens 
referred to are so curved and twisted out of shape as to render their representation 
inadvisable. 
CAMPSURUS. 
Campsurus, Eaton, Ent. Monthly Mag. v. p. 83 (1868); Rev. Mon. Ephem. p. 38, t.5 (adult 
details) (1883). 
A genus spread over a large part of South America, and extending northwards 
to Texas; species probably numerous. In dried specimens the chief distinctions 
lie in the ¢ genitalia; but sometimes the facies of the neuration, especially that of the 
hind wings, may serve for their discrimination. Female specimens can seldom be 
identified with certainty, apart from flies of the other sex associated with them in the 
same localities.
