58 THE GYPSY MOTH APPENDIX. 



joint stout, scarcely reaching the margin of the head ; sec- 

 ond joint over three times as long as basal joint ; third and 

 fourth joints each about one-half as long as second joint. 

 Legs pale amber, darkening to brown on tibiae ; tarsi dark 

 brown . 



This species is widely distributed throughout the region 

 infested by the gypsy moth, but does not occur in such 

 numbers as do its allies in the genus Podisus. I have taken 

 specimens in Medford, Maiden, Saugus and Revere, while 

 Professor Uhler records it from Andover, Lynn and 

 Chaiiestown. 



EUSCHISTUS POLITUS Uhl. (Plate 2, Fig. 12). 



A rare member of our heteropterous fauna is a small 

 Euschixtux, which, previous to the past summer, had been 

 occasionally taken under such circumstances as to give the 

 impression that it possesses predatory habits. Specimens 

 of the insect submitted to Prof. P. R. Uhler were considered 

 by him to be new to science, and at my request he has very 

 kindly prepared the following description : 



Euschistus politus. New sp. "Pale dull fulvous, or rufo- 

 fulvous, suboval, with the humeral angles almost rounded and 

 very moderately prominent. Head narrow, as in E. tristlgmus 

 Say, deeply and finely punctate, the tylus prominent at tip and a 

 little longer than the lateral lobes, the lateral lobes deeply siuu- 

 ated, with the outer margin blackish. A black line extends from 

 the eye to base of antennae ; antennae (Plate 2, Fig. 13) clay yellow- 

 ish ; the basal joint short, hardly reaching the apex of head, 

 marked with a few black points ; second joint longer ; third a little 

 longer than the second ; fourth longer, dusky at tip ; fifth a little 

 longer than the fourth, fusiform, blackish excepting at base ; 

 rostrum pale testaceous, slender, with the seta? piceous, reaching 

 to the posterior coxas. Pronotum much wider than long, polished, 

 closely and finely punctate with brown ; the lateral margins very 

 slightly sinuated, smooth, ivory white ; the submargius blackish ; 

 humeral angles triangularly rounded ; posthumeral margins almost 

 straight. An obsolete, callous, imperfect curved line extends 

 between the humeral angles. Scutellum narrow and bluntly 

 rounded at tip, where it is also slenderly margined with white ; 

 the surface is less densely punctate in small spots. "Wing-covers 

 (Plate 2, Fig. 14) closely punctate ; membrane a little brownish,
