THE STATE ENTOMOLOGIST. 



I subjoin the original description of this fl}^ which is of a yellow color, 

 marked, as in the figure, Avith black : 



Chalsis MARi.E, Riloy — 2 I yellow, beautifully marked with black. Head, yellow with an arcu- 

 ate black mark behind base of the antenuJB, connected with a fine short longitudinal black line lead- 

 ing to lower ocellus, and from thence to posterior margin ol occiput which is margined with black; 

 prothorax with a medium black dot. Antenna: (scape plus i) joints) 10-jointed; scape fulvous with su- 

 perior edge black, flagellum dark brown or black. T/foro.r with large shallow close-set punctures j 

 mesothorax somewhat striated transversely, trilinear witli black, llie three lines connected by a 

 transverse line which separates the prothorax from mcsothorax, the middle line straight, the outer 

 ones deeply imi)ressed, approaching behind and connected on tlie posterior margin by a short trans- 

 verse line, and then suddenly divergmg on lateral suture of scutellum; a longitudinal black dot on 

 each side over tegulre; scutellum edged anteriorly with black and with a central longitudinal black 

 line; basal margin of metothorax, with a spot on each extreme side and a large subtriangular marlc 

 on disk, black; jileuraj with two black lines on each side. Wings hyaVme. Abdomen yellow with 

 sometimes a faint tinge of gi'een, black at base and tip, and each segment banded with black superi- 

 orly; petiole yellow, black at tip above. Legs yellow, the tarsi inclining to fulvous; abroad line on 

 posterior coxa; above, and interior edge of femora and tibje, and tip of femora, black; the femora 

 about as large as abdomen with over 12 minute black spines on inferior edge. Average length ((.•i(»' 

 inch. 



cf differs in the less pointed abdomen, and somewhat longer petiole, in the scape of antenna? not 

 being black superiorly and being much more robust; in the flagellum being of the same color as 

 scape, and in thecoxa; having a black line both above andbeneath. Average length O.l.i. Described 

 from 10 (^s 4 § s bred from Attacus Polyphemus and 2 i^s 1 § s bred from .1 Promothea. Variable in size 

 some (-^ |-^ Ijeing much larger than some J 5 • 



Say's amwna, bred from a Thecla, in which no sexual diflerence is mentioned, somewhat resein- 

 l)les the p of this species, butdiflers from it principally in having the thorax quadrilinear with black, 

 the petiole black, the pleura black, with four yellow spots, and in the thighs having six or eight y./ro/H- 

 inent spines, the superior one divided into three or four. 



The Cecropia Cryptus — (Cryphis extramatis, C'resson). — Another Ich- 

 neumon-fly often infests the Cecropia worm, the larvae filling its cocoon 

 [Fig. 41. ] so full of their own thin ])archment-like 



cocoons, that a transverse section (Fig. 40) 

 bears considerable resemblance to a honey 

 comb. The flies issue in June, the female 

 presenting the appearance of Figure 41. a.

 wings have a smoky

 viewed under a micro- 

 scope, b}" innumerable 

 little hooks regularly 

 arranged over their sur- 

 face as at d. The an- 

 tennfc have a ]xile annulus, the head and thorax are black, the abdomen 

 reddish-browii except near the end where it is l)lack tipped with white; and 

 the legs are reddish ringed with black. The male has a more slender abdo-> 

 men which lacks the ovipositor and the white spot at its tip. This sex 

 has not yet been described; for what Mr. Cresson took to be the male 

 turns out to be the male of another species (C. nvneivs, Say), which infests 

 the Promothea worm, and the female of which has a much shorter ovipositor
