18G Rev. A. E. Eaton on new sj)ecies of 



wing that are greyish towards the subcosta, and some in the fore 

 wing, viz., the cross veinlets anterior to the sector, many of those 

 anterior to the pobrachial in the basal half of the wing, and a few 

 of those nearest to the base in the areas intervening between that 

 nervure and the 1st axillar nervure ; the great cross vein also is 

 black between the subcosta and the radivis. Body and legs 

 yellowish ochre, with black markings ; those of the head and 

 notmn are of a pattern common in the genus, comprising the edge 

 of the occiput on each side behind the eyes, and two longitudinal 

 stripes extending from the pronotum (where they are parallel with 

 each other) to the peak of the scutellum, angulated on the meso- 

 notum and confluent just before their termination with a rounded 

 pitch-brown spot on the succeeding part of the notum on each 

 side. On each side of the thorax is a small spot in front of the 

 roots of the costa, and a minute spot just above the coxa at the 

 posterior angle of the metapleuron. The basal and the posterior 

 margins of the hind coxa, and the anterior tibia, narrowly, at both 

 extremities, are blackish. Dorsal abdominal markings — two sub- 

 continuous and subparallel series of strongly marked linear stripes, 

 rather near each other, extend from the 3rd to the 9th segment 

 down the middle of the back, and are slightly coarctate at the 

 bases of the 3rd to the 8th segments ; between these in each seg- 

 ment is a pair of divergent streaks fi*om the base of the segment 

 that are associated with the dorsal vessel, and are less distinctly 

 defined than the linear stripes: in some of the segments the 

 streaks are considerably abbreviated ; in the 2nd segment (which 

 is marked with a round spot on each side just above the pleura) 

 the stripes are represented by single dots ; at the joinings of the 

 1st to the 8th segments the stripes are crossed by single fine black 

 lines that do not extend to the pleura. At the pleura, segments 

 2 — 9 have each a small triangular spot at the base, and segments 

 4 — 7 each have a fine curved longitudinal line from the margin 

 near the posterior angle, which is reduced to a dot in segments 3 

 and 2. "Venter bilineate longitudinally ; the lines subparallel, dis- 

 continuous, and some of them at their anterior extremities slightly 

 inflected. Sette fuscous, with opaque joinings, and some of them 

 here and there blackish. Length of body about 12, wing about 

 13 mm. 



2. Potamanthus formosiis, sp. nov. 

 Imago [dried). — A species of elegant appearance, with trans- 

 parent wings of a light flavescent tint : the fore wing strongly 

 blotched with light reddish pitch-brown in the marginal area, and 

 sparsely freckled faintly in the disk with light greyish or reddish
