LACE-BUGS. 45 
FAMILY TINGITIDAE. 
(Lace-bugs). 
Members of this family of bugs are small and feeble beings, 
who occur in large numbers upon the under side of the leaves 
of various trees and shrubs from midsummer till autumn. Here 
old and young crowd together, and, attached by their beaks, 
suck the sap. They deposit their eggs near the midribs and 
veins. These beautiful insects are the most easily recognized 
of all Heteroptera, and as they lack the unpleasant odors of the 
majority of other bugs, they can be handled with impunity... 
Their wing-covers are reticulated in the most bewildering man- 
ner, and are very gauze-like in structure; the prothorax is 
Fic. 38.—Corythuca arcuata Say. Adult,eggsandnymph. After Comstock, 
Div. of Entomology, Dep. of Agriculture. A variety, after Uhler. 
greatly expanded, and beautified like the wing-covers. This 
beauty of structure is still more improved by black or brown 
bands. 
Lace-bugs possess no ocelli; the beak and feelers are four- 
jointed ; the scutellum is absent or rudimentary, but is replaced by 
the angular hind portion of the pronotum; the tarsi are two- 
jointed. The insect shown in Fig. 38, Corythuca arcuata Say, is 
common upon the under side of several kinds of oaks; C. jug- 
landis is found in similar positions on the butternut; C. gossypit 
infests the cotton-plant in the South; another species occurs upon 
the leaves of beans.
