14 PROCEEDINGS OP THE ACADEMY OP [1886. 



surrounded bj' a small pale brown clouded spot. Each cell in 

 the apical half of the wing has, midway between the veins, a pale 

 brown cloud, approximately taking the shape of its cell. At the 

 base of the pterostigma a small black spot, and another at the 

 junction of the cubitus and posterior margin. Length to end of 

 wings about 2 millim. 



Southern Texas. One specimen discovered while beating a 

 live oak thicket on the prairies. 



Csecilius impacatus. 



Pale yellow and brown. Antennae much shorter than wings, 

 fuscous, the basal joints and the first long joint in part, pale ; 

 palpi fuscous. Nasus pale, somewhat clouded with brown ; rest 

 of head j^ellow with brown markings, the space before and 

 directly around the separated golden colored ocelli, brown ; a 

 brown band on each side bordering the inside margin of the ej^es, 

 and another on each side of the dividing occipital suture, reach- 

 ing each posterior ocellus. E^^es brown and pale, about con- 

 colorous with the other parts. Mesothoracic lobes brown, deeper 

 colored anteriorl}^, the sutures pale j'ellowish ; rest of thorax pale 

 yellow and brown. Abdomen pale, the sutures brown, and brown 

 markings at the apex. Legs pale, the apical tarsal joint darker. 

 Wings clear hyaline, the seemingl}^ delicate veins pale brown. A 

 small black spot at the base of the pterostigma, and another at 

 the junction of the cubitus and posterior margin. Otherwise the 

 wings are entirely unmarked. About 3'5 millim. long to end of 

 wings. 



Penn. (near Philadelphia). I beat one specimen from the 

 branches of a beech, and on account of its constant activity found 

 it very diflScult to capture, almost hopelessly mashing it in doing 

 so. 



Fsocus campestris. 



Luteous and pale brown. Antennae about as long as the 

 wings, fuscous, the basal joints luteous ; palpi pale, fuscous on 

 the extreme apex. Nasus short, lineated with brown, and 

 sparsely pilose ; rest of head luteous, a brown irregular patch on 

 the margin of nasus before the ocelli ; a narrow black line 

 dividing the occiput ; faint fuscous maculose markings on each 

 side, within the margin of the eyes. Ocelli black ; eyes brown, 

 with paler reflections. Lobes of the thorax brown, the sutures
