766 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



Pale yellowish brown, with very regular and dense black puncta- 

 tion; pronotum and scutellum with a narrow impunctate median 

 line becoming obsolescent posteriorly. Length 13-14 mm. 



This curious species is occasionally found resting on tree trunks, 

 especially hickory. It has been reported as attacking the larvae 

 of the gipsy moth.

Thyanta Stal. 



Species of moderate size having the orificial canal long and 

 gradually tapering; tylus at least as long as juga; pronotal 

 margins simple ; the tibiae sulcate above. 



Key to Species. 



Form very broadly oval ; length 9 mm calceata 



Form more elongate ; length about 1 1 mm custator 



T. custator (Fabricius). 



Syst. Rhyng., 164, 1803. 



Color very variable, pale green to dark olive, sometimes with a 

 purplish band across pronotum; median line of scutellum some- 

 times pale; margins of pronotum and hemielytra sometimes red- 

 dish yellow. Antennae reddish brown. Ventral surface pale. 



Surface densely and confluently punctate, except lateral margins 

 of pronotum and hemielytra at base. Lateral pronotal angles 

 prominent but not spinose. Male genital plate with slightly promi- 

 nent lateral angles. Form rather elongate oval, sometimes 

 variable. Length 9-1 1 mm. 



This species has been taken in Massachusetts and probably 

 occurs in Connecticut, as it is common to the southward. 

 T. calceata Say. 



Het. New Harm., 8, 1831. 



Differs from the preceding in its smaller size, shorter scutellum, 

 constant form and coloration, the black markings on margin of 

 head and pronotum, the purplish pronotal band, and the spots of 

 the membrane being always present. The male genital plate is 

 somewhat narrower, with very prominent lateral angles. Form 

 broadly oval. Length 9 mm. 



A rare species, closely related to the preceding.

A characteristically southern group of brightly colored species 

 having the metasternal orifices inconspicuous, located near the 

 coxae, not elevated, and without a prolonged canal, juga not longer
