SPECIES THAT WERE MOST NUMEROUS. 



1. Cicadula 4-lineata Forbes (Fig. 1 of plate I) was the most common' 

 species everywhere. At the college and where the muck had considerable 

 clay in it, they could be taken by the hundred at almost any time in the 

 season. The species is greenish brown, with yellow scutellum, and head 

 spotted as shown in the figure. 



2. Empoasca malihe'B. (Fig. 2 of plate I). This is a pretty little 

 yellow species with transparent greenish wing covers and green legs. It 

 was very common through the season after July. At Kalamazoo many 

 were found down in near the heart on blanching celery. It is probable 

 that they help spot the white stalks. They breed on the plants. 



3. Platymetopius acutus Say (Fig. 3 of plate I) was common the lat- 

 ter part of the season. The young were found on the plants early this 

 fall. The species probably does little harm as it prefers to be high up on 

 the leaves instead of on the stems. To the naked eye it is a dark brown 

 and can be easily told by the acute projection of the head. 



4. Athysanus mstahilis* n. sp., Van Duzee (Fig. 4 and 4a of plate I). 



Form of Deltoceplialus inimicus Say. Black, dotted and marked with fulvous as fol- 

 lows: hind edge of the vertex, a dot, sometimes wanting, touching this either side of 

 the middle, another near each eye, two marks on the disc, a Ime before each of these, 

 an angular mark at apex including a short longitudinal dash, a dot on the temples, six 

 or eight arcs and the central line on the front, the latter expanded on the clypeal 

 suture, two dots on the base of the olypeus, another on each lora, a spot on the cheeks 

 and their slender outer edge, the irrorations of the pronotum and a few large spots on 

 its anterior edge, six spots on the scutellum — four marginal and two discal — and its 

 median line, knees, a transverse band on the femora and the slender hind edge of the 

 abdominal segments. Posterior legs pale, more or less clouded with fuscous, with the 

 inner face of the flattened tibia black. Elytra pale, slightly clouded at apex, the are- 

 oles broadly margined with fuscous, nervures whitish. Last ventral segment of the 

 female long, feebly arquated either side of the middle, with the lateral angles promi- 

 nent. Valve of the male short, plates triangular subacute. Length 4-4}^ m. m. 



Quite common at the college through August and September. Mr. Van 

 Duzee has the specimens of the same species from Colorado also. 



5. Megamelus piceus n. sp., Van Duzee (Fig. 5 and 5a plate I). 



Piceous-black; base of the vertex, keels and narrow hind edge of the pronotum, disc 

 of the mesonotum. or at least its carinse, disc of the tergum, especially towards its base 

 and apex, and the edge of the dorsal keel; the genital segments and sometimes the base 

 of the venter, brownish yellow. Face pale shaded to brown above, clypeus deep black. 

 Antennae, rostrum, tylus, and legs pale, soiled yellow, the later lineate with brown. 

 Elytra reaching to the second abdominal segment in the branchypterous form, with 

 the apex truncated, piceous-brown, or even black, with the apical edge white more or 

 less broadly interrupted with black at the middle; nervures strong, granulated. In the 

 macropterous form the elytra extend considerably beyond the tip of the abdomen about 

 as in Liburina pelbicida; they are smoky with pale granulated nervures, the exterior 

 and interior of which are forked at about three-fourths their length. Pygafers of the 

 male cylindrical, on their ventral aspect cut out for about one-half their length and 

 carrying on the broad base of this incisure a broad and short projection extended into 

 a short conical divergent tooth at each angle, beyond this are the incurved spine-like 

 stylets included between the long slender ventral projections of the plates. Length, 

 23^ to 3 m. m . 



New York and Michigan. Described from many examples of both sexes taken in 

 western New York on grass in low swampy meadows in August and September, and 

 one female taken on celery at Kalamazoo, Mich., August 26, 1893, by Mr. G. C. Davis. 



In this species the vertex is shorter and broader, the pronotum shorter and the meso- 



* This and the following species were foand to be new to science and Mr. E. P. Van Dozee, a specialist 

 on Jassidse, to whom they were sent, has kindly consented to describe them. His same descriptions will 

 also appear in the Canadian Entomologist.
