lice or aphids, though the ill-defined, brown spots suggest the possi- 

 bility of their having been affected by sun scald or some obscure 

 disease. The spotting of the tender leaves is somewhat the same 

 as that on currant foliage, produced by the 4-lined leaf bug 

 (Poecilocapsus lineatus Fabr.). Many tips were thus 

 affected on the apple trees of Mr S. E. Miller of Germantown and 

 the insect was somewhat abundant in the orchard of Mr C. R. 

 Shons of Washingtonville, the nymph, presumably of this species, 

 being taken in the last named orchard June ist and three adults 

 June 30th. The latter were secured only after repeated collecting, 

 since the insects were by no means abundant. It is possible that 

 some of the work described above is due to the operations of the 

 red bug (Heterocordylus malinus Reut.) a species 

 having similar habits. 



These two forms resemble each other very closely and we take 

 this opportunity to put on record their salient characteristics. 



Lygidea mendax Reut. Adult. Length 6 mm., rather slender, the 

 width 2 mm. The color varies from yellowish red to rather bright 

 red and may be variably suffused with fuscous, this invariably form- 

 ing a median stripe extending from the scutellum to the tip of the 

 wing and including the membrane. Head dark red or yellowish red, 

 the clypeus fuscous ; rostrum extending to the posterior coxae, a 

 variable fuscous yellowish, fuscous basally and apically. Eyes 

 large, very protuberant, coarsely granulate. Antennae fuscous, 

 hairy, first segment stout, with a length only half that of the greatly 

 produced, slender second segment, the third segment slender, about 

 half the length of the second, the fourth a little shorter than the 

 third. Pronotum coarsely punctured, sparsely setose and margined 

 posteriorly with a broad, black line, sometimes slightly broken 

 mesially. Scutellum reddish or yellowish red, the posterior half, 

 especially the submedian areas, a variable fuscous ; the clavus, the 

 internal angles of the wing, and the membrane mostly fuscous, 

 forming a variable broad median stripe. Abdomen a variable red. 

 Coxae red, trochanter and femora pale yellowish; tibiae fuscous 

 yellowish or fuscous, the biarticulate tarsi a variable fuscous. 



Partly grozmi nymph. Length 3 mm., width 2 mm., bright red, 

 the tips of the wing pads a variable fuscous. Antennae yellowish 

 fuscous. Legs mostly fuscous yellowish, the tibiae and tarsi 

 «;lightly darker. 



Heterocordylus malinus Reut. Length 6 mm., rather slender, 

 width 2 mm., yellowish red or dark red with conspicuous fuscous 

 markings and sparsely clothed with fine, whitish or yellowish white 

 scales. Head triangular, mostly fuscous, the front sparsely clothed 

 with small, whitish scales; rostrum a variable reddish brown and 

 extending nearly to the posterior coxae. Antennae dark reddish 

 brown, the first segment stout, length about ys that of the greatly 

 produced, more slender second segment, the slender third segment
