This species I have received in exchange from a number of corre- 

 spondents as Agallia flaccida Uhler, and have so used the name myself 

 in exchanging and in the List of Muskoka Hemiptera. It seems to have 

 been an early manuscript name of Mr. Uhler. I append a translation 

 of ]M. Provancher's description, as the periodical in which it occurs 

 seems to be rare and difficult to obtain. For the copy in my possession 

 I am indebted to the kindness of its editor, 



"Bythoscopus 4-punctatus, 4-pointecl Bythoscopiis^ n. sp. 



"Length, .12 inch. Of a yellowish lirovvn, inore or less obscure. Head varied 

 "with yellow and brown, with two black points on the anterior margin. Prothorax 

 " with two large black points ahnost on the posterior margin, in line with those ot the 

 " head ; other less distinct black points sometimes appear in advance of these. 

 "Elytra soiled yellow, the nerves paler. Beneath brown, feet yellowish. Common. 

 "Very near the preceding {By. sangninolentits) but easily distinguished however by 

 "the presence of the two black points on the posterior m.irgin of the prothorax." 



This is a very abundant species in Western New York from early in 

 May until September, and in fact the year round, as it appears to hyber- 

 nate in tlie adult state as do many if not all the Jassidis. 



Genus PEDIOPSIS Burm. 

 Head entirely or almost entirely deflexed, viewed from above form- 

 ing a narrow margin to the front of the prothorax ; vertex confounded 

 with the front, with the eyes, as wide as the pronotum. Ocelli on the 

 face about opposite the middle of the eyes, from which they are less 

 distant than from each other. A more or less obvious depression crosses 

 the middle of the face a little above the ocelli. Front bounded by a 

 slight depression, not quite reaching the line of the ocelli. A sharp 

 oblique ridge from the outer angle of the eye to near tiie base of the 

 clypeus, shielding the base of the antenna. Lorce prominent, tumid. 

 Outer cheeks narrow below, where they are largely coveed by the lorse. 

 Clypeus oblong or ovate, usually with a lateral depression before the 

 lorae that sometimes extends across the apex. Rostrum short, scarcely 

 attaining the base of the intermediate femora; composed of three joints, 

 the basal hidden beneath the clypeus. Pronotum short and broad, tri- 

 angular before, sides very short, latero-posterior angles rounded; posterior 

 margin broadly, sometimes angularly, concave. Scutellum broad-tri- 

 angular, transversely depressed before the apex, which is sub-acute ; 

 slightly calloused within the basal angles. Elytra thin or membranaceous, 

 costa more or less arquated, apex rounded, mner margin straight ; mem- 

 brane without an appendix. Ordmarily there are six closed cells on the
