JOUKNALi OF ENTOMOLOGY AND ZOOLOGY 117 



the sternum broadly black; in the female the pleural pieces and ven- 

 tral and genital segments are bordered with black and the sternum is 

 narrowly black. 



Described from numerous examples beaten from sycamore trees 

 at Hamburg and Gowanda, N. Y., in July and August. Mr. Heide- 

 mann has sent me the manuscript name of Plagiognathus albatus 

 Uhler for this species but the description seems never to have been 

 published. This insect varies much in the extent of the dark mark- 

 ings and in some they coalesce and are so extended as to give the 

 insect a strong resemblance to Plagiognathus obsciirus, but the long 

 female oviduct, the unspotted tibiae and irregularly dotted femora 

 will distinguish it from that species and genus. 



Psallus vaccini n. sp. 



Allied to ahshithii Scott. Smaller and paler than juniperi Held. 

 Oblong; white; minutely white pubescent; irrorate with minute 

 fuscous points which omit the nervures. Length 3;^ mm. 



Head a little oblique; as seen from before longer and more 

 pointed than in the allied species; viewed from the side produced 

 beyond the eye for about the width of the eye. Clypeus small, dis- 

 tinct, the basal suture obvious but not conspicuous, scarcely attaining 

 the line of the antennas. Eyes oval, nearly vertical, strongly gran- 

 ulated, reaching well down toward the gula. Antennas long, basal 

 joint but little surpassing the clypeus; third but little shorter than 

 the second; fourth short and setaceous, little longer than the basal. 

 Pronotum short, scarcely longer than the head; anterior margin 

 feebly sinuated; base and sides straight, the latter strongly oblique. 

 Scutellum small, equilateral. Elytra long, parallel, about two 

 times the length of the abdomen. Hind femora rather broad and 

 flattened. 



Color whitish tinged with testaceous on the head, callosities and 

 scutellum; the pronotum, scutellum and elytra dotted with fuscous, 

 these dots fewer on the disk of the elytra anteriorly and on the base 

 of the cuneus, sometimes wanting on the disk of the pronotum where 

 there may be a dusky cloud from the dark mesonotum showing 

 through. Elytral commissure with a brown line beyond the tip of
