MonelUa marginella (Fitch), Fig. 7. Specimens of this species 

 which answer fully the description by Fitch, and which seem to the 

 writer to be quite distinct from caryella, were taken at Portland, 

 Detroit and Kansas City from leaves of Carya alba, upon which they 

 were quite plentiful. The sensoria on basal half of joint 3 of the 

 antenna vary from 4 to 7 in number. 



Monellia maculella (Fitch) (?), Fig. 8. What I take to be this 

 species has about 6 longitudinal rows of small blackish tubercles 

 upon the dorsum of the abdomen, and both anterior and posterior 

 femora have a black ring or spot a short distance from their distal 

 ends, but the tarsi are not perceptibly blackish and the maculations 

 upon the wings as described by Fitch, are indistinct or lacking in 

 my specimens, all of wliich are in balsam. 



Taken at Detroit on Carya alba, and at Lansing, Washington, 

 D. C, and Fort Collins, Colorado, on Juglans nigra. 



MyzocalUs bella (Walsh), Figs. 9, 10. This very handsome lemon 

 yellow species, with wings that have heavy black costal margins and 

 very small costal cells, was takerf at Portland, Detroit and Rochester, 

 apterous and alate, on the upper side of the leaves of Quercus rubra. 

 The apterous females have a double row of large black spots upon 

 the dorsum of the abdomen, there being about seven to ten spots in 

 each row and all closely placed. In addition, there are numerous 

 stout capitate hairs over the body rising from tubercles. The an- 

 tenna of an alate female taken at Rochester is shown at figure 9. 

 The apterous females vary from yellow to a msty brown in color, 

 and have conspicuous white powdery patches above upon the vertex 

 of the head and upon lateral margins of meso-thorax and abdomen. 



MyzocalUs walshii (Monell), Fig. 11. This species, which seems at 

 first to be a miniature of M. bella, was correctly considered to be 

 quite distinct by Mr. Monell. The very long antennal filament ex- 

 ceeding even the third joint in length would alone separate this 

 species from bella. The capitate hairs are long and strong. This 

 was a common species, but was noted only at Lansing, Portland and 

 Geneva on Quercus rubra. 



MyzocalUs asclepiadis (Monell), Fig. 12. This species was taken 

 in good numbers, both alate and apterous, from Asclepias sp. at Chi- 

 cago, Detroit and Geneva. It seems to be readily separated from an 

 allied species, also occurring upon the milkweeds, by the long an- 

 "tenna, usually fully as long as the body, and the longer antennal 

 spur, which, though variable, always distinctly exceeds the sixth 

 joint.
