^62 THE CANADIAN ENTOMOLOGIST. 



7-14 a little stouter than joints .2 to 6, and much shorter, joints 11-13 

 being hardly longer than wide. Tarsi shorter than their tibite, the claws 

 with a tooth within. 



This genus, although closely allied to Biorrhiza, Westw., is readily 

 separated by the absence of the middle frontal ridge between the 

 antennse, by the shape of the scutellum and by the claws having a tooth 

 within. 



The type of the genus is Biorrhiza forticornis, Walsh. 



Parateras, gen. nov. 



Last joint of labial palpi somewhat enlarged, ovate. Antennse 14- 

 jointed, the third joint long, but much shorter than joints 4-5 united, 

 joints 11-13 scarcely twice as long as thick, the last joint hardly so long 

 as the two preceding united. Head and thorax alutaceous or finely 

 shagreened, the mesopleura finely delicately sculptured, without a femoral 

 fovea. Mesonotum with two distinct parapsidal furrows which converge 

 and meet at base of the scutellum. Scutellum smxll, highly convex or 

 elevated, with a distinct tranverse fovea at base (in reality two fovese 

 united). The hind tarsi are longer than their tibise, the claws with a 

 distinct tooth at base beneath. Abdomen polished, bare. This genus 

 comes nearest to SpJueroteras, Ashm., but is readily separated by having 

 14-jointed, not i3'jointed, antenna, by the scutellum having a fovea or 

 fovese at base, and by the hind tarsi being longer, not shorter, than their 

 tibiae. 



Parateras Hubbardi, sp. n. 



Agamous 9. — Length 2 mm. Head and thorax reddish-brown, 

 the vertex and scutellum somewhat obfuscated. Abdomen black, piceous 

 towards base. Antennte with the first two joints ferruginous, dusky 

 above, the flagellum black or brown-black, except first joint basally. 

 Legs, including coxre, pale ferruginous, with all the tibioe, or at least 

 outwardly, dark fuscous or blackish, the tarsi more or less fuscous. 

 Abdomen with the second segment not quite occupying half the whole 

 surface, the third segment dorsally not quite as long as four and five 

 united, the fifth about two-thirds the length of the fourth, the following 

 segments retracted. 



Hab. — Detroit, Michigan. 



Described from two specimens received from Mr. H. G. Hubbard, 

 to whom the species is dedicated.
