 Descriptions of New Species.

Div, MIRARIA. 



TERATOCORIS, Fieb, 



I. T. herbaticus, new sp. 



Pale greenish yellow, or straw color, moderately polished, minutely pubescent . 

 the head shorter and wider than in the next related genera; the body much narrower 

 in the male than in the female. Vertex broadly depressed behind, with the occiput 

 raised into a transverse curved ridge, which rests intimately against and a little over 

 the front of pronotum ; the middle Hue impressed only near the base. Male with a 

 narrow black vitta extending from behind the tylus to the tip of scutellum. Eyes 

 pale brownish, more prominent in the male than in the female. Antennae about as 

 long as the entire body to the tip of the wing-covers, moderately dusky, gradually 

 becoming more slender towards the tip, the second joint longest, the third longer than 

 the fourth. Rostrum reaching to the middle coxae, pale piceous at base and tip. 



Pronotum trapezoidal, moderately fiat, the sides slightly excurved behind th 

 middle, the anterior portion ot the lateral margin strongly reflexed, the posterior 

 margin distinctly sinuated, with the postero-lateral angles callous and prominent, the 

 surface rugulose, coarsely punctate behind the discal prominence, posterior lobe de- 

 pressed ; anterior submargin resembling a wide collum with an impression in the 

 middle ; and the males have a dark streak in the suture of the anterior angle. Legs 

 minutely hairy, tinged with brown around the knees and on the tarsi, and the femora 

 marked with a few dark points. Scutellum moderately convex, widely uncovered at 

 base, the tip smooth, prominent, cylindrico-convex. Hemelytra narrow and almost 

 parallel sided in the males, but wider exteriorly, more curved, and with the costal 

 margin more reflexed in the females ; the surface obsoletely wrinkled and obscurely 

 punctate, and sometimes a little dusky on the inner margin of curium and on the base 

 of the elsewhere colorless membrane. The corium, clavus and membrane of the fe- 

 male are shorter than in the male and the surface of the two former is more coarsely 

 and distinctly scabrous. Venter of male much narrower than the wing-covers ; of 

 the female almost as wide as the wing-covers ; the male genital segment is set with 

 stout-erect bristles, and the appendage of the sinistral side is composed of a long com 

 pressed basal strap to which is attached a longer curved corneous tapering hook. 



Length to end of venter (j 1 3^ — 3^, Q 4— 4} mm. To tip of membrane q 1 4 to 

 4|, 4}, mm. Width of base of pronotum I--1', mm. 



Specimens of the male are in the collection of the United States 

 National Museum, which were obtained in the vicinity of Ungava Bay, 

 Labrador, and presented to that institution by L. M. Turner. In my 

 own collection is a mutilated female (alcoholic), which was taken near 

 Hopedale, Labrador, by Dr. Packard, who kindly gave it to me. It 

 seems likely that this species is closely related to T. hyperboreus Sahib. , 

 which is found in Lapland ; but in the absence of specimens for com- 

 parison it is impossible to decide with certainty.
