Apterous rii'iparous female. General color of body yellow. Ryes 

 reddish brown. Antennae with segments I, II and III (except ex- 

 treme tip) light straw-colored; IV, V, VI (except spur) and tip of 

 III black. VI spur dusky but somewhat lighter than base. Legs with 

 tarsi and joints black, remainder lighter. 



Structural characters as in alates, except no secondary sensoria. 



Measurements: Body, length (including both cauda and frontal pro- 

 tuberance) 2.04-2.28 mm.; width of thorax, 0.51-0.54 mm.; antennae, 

 total 1.22-1.62 mm.; Ill, 0.408-0.553 mm.; IV, 0.221-0.306 mm.; V, 0.204- 

 0.272 mm.; VI, base, 0.136-0.170 mm.; VI, spur, 0.136-0.170 mm.; cor- 

 nicles, width at mouth, 0.032-0.035 mm.; cauda, 0.085-0.119 mm.; hind 

 tarsi, 0.153-0.170 mm. 



This species seems typical of the genus except for the fact 

 that both oblique veins of the hind wings are distinct. How- 

 ever, as Gillette 13 states, "the presence or absence of the vein 

 should not be given generic importance." From the figures of 

 T. z'ernicosa Gillette, the species seems very closely related to 

 the one described here. As only apterous oviparous females of 

 that species were described, it cannot now be determined 

 whether or not they are synonymous. 



A Gynandromorph of Callosamia angulifcra and Melitaea phaeton 



aber. streckeri (Lep.). 



Doris M. Armstrong, of Brockett Point, Branford, Connecticut, has 

 sent me for examination two very interesting specimens. One is a per- 

 fect gynandromorph of Callosamia angulifera. The wings of the left 

 side are of the dark color of the male and the antenna of this side is 

 male. The wings and antenna of the right side are female in color and 

 character. The specimen was a captured one. 



Perfect examples of gynandromorphism are evidently of rare occur- 

 rence and they are more interesting when the sexes of the species are 

 so different in appearance. 



The other example is an aberrant specimen of Melitaea [>haetti 

 Drury, and is very similar to the form described by Ellsworth in Hnt.
