PEDICIA. 273 



the front, very near the basis of the antennae. I do not see them, 

 however, on the front of a female P. rivosa, which I can lilvewise 

 compare. This may be owing to shrinkage. Pedicia and Ti^icho- 

 cera would thus afford the only known instances of ocelli among 

 the Tijyulidse.

He'ad and palpi brown, the former with a grayish bloom ; an- 

 tennae not much longer than the head, yellowish-brown ; flagellum 

 stout at the basis, gradually attenuated. Thorax pale brown, 

 Avith a silvery gray reflection ; a brown double stripe in the 

 middle above, and less distinct stripes on the sides ; another 

 brown stripe runs from the collare to the root of the wings, and 

 from there to the hind coxse. Abdomen with a row of brown 

 spots on five segments ; they are elongated and pointed behind, 

 with a yellowish-red spot at the basis of each ; the remaining 

 portion of their intervals is silvery white ; venter with a longi- 

 tudinal brown band, interrupted by a reddish tinge at the in- 

 cisures of the segments, and somewhat attenuated in the middle 

 of each segment ; tip of the abdomen brownish. Feet stout, 

 hairy, femora tawny ; their tips brown ; tibiae and tarsi brown. 

 "Wings hyaline ; a brown band along the costa, another along the 

 fifth longitudinal cell ; they coalesce at the inner end of the basal 

 cells, and are connected by a croes-band along the central cross- 

 vein ; the band along the costa is yellowish in the costal cell, apd 

 somewhat expanded round the origin of the priefurca. 



Hah. Trenton Falls, N. Y. ; New London, Conn. ; Massa- 

 chusetts (Mr. Scudder). This species seems to be chiefly north- 

 ern ; I have seen a specimen, however, which was said to have 

 been caught in Maryland. 



At first sight, this species looks very like the European P. 



rivosa L. ; still the longitudinal brown band along the abdomen, 



in the latter, seems to be more continuous, and not composed of a 



series of spots. A careful comparison of a larger number of
