INSECTS AFFECTING THE ORANGE, 



Fio. 13. Com ys bicolor. (After Howard.) 



The foregoing parasites, belonging to the genus Coccophagus, hare 

 eight-joiuted antennae. In the genus Comys the antennae are eleven- 

 jointed, the shield upon the back 

 (scutellum) terminates in a tuft of 

 long, stiff hairs, and the fore wings 

 are clouded with brown. 



Comys Mcolor Howard (Fig. 13) is 

 the largest parasite of Lecanium lies- 

 peridum. It has dark-brown eyes, 

 head and face yellowish brown, col- 

 lar shining black, remainder of tho-. 

 rax yellowish-brown, with black 

 hairs; abdomen shining black. The 

 first and second pairs of legs are 

 respectively dark and light brown, 

 with the thighs white below, fn scons 

 above; the hind legs dark, with silvery white tarsi; length 1.75 mm (007 

 inch). This parasite is found in company witb Coccophagus Iccanii. 



Being larger it inhabits the 

 full grown scales, while the 

 Coccophagus attacks only those 

 which are partly grown. The 

 Bark-ltee which contain pupae 

 of this parasite turn black as 

 with the preceding species.
