85 MAINE AGRICULTURAL EXPERIMENT STATION. I913. 



They had probably merely ahghted there as a resting place as 

 no nymphs were present. The currants were not adjacent to 

 willows, though willows were not far distant. 



34-06, Veazie, June 19, 1906. Winged form on Populus bal- 

 samifera. 



51-10, Veazie, July 7, 1910. Balsam Poplar. Apterous and 

 alate females and pupae. 



Melanoxantherium salicti Harris. A species which I have 

 taken for salicti was collected in Maine on willow in 1906. 

 Head slaty black, not glistening, antenna black except at base. 

 HI with about 22 sensoria irregularly placed (Fig. 43, B.). 

 Eyes black. Prothorax black, lateral tubercles present. Fig. 

 44, B. Thorax black with scutel lobe brownish, wings hyaline, 

 with pale brown veins and stigma the color of veins, legs with 

 femora bright yellow, tibiae yellowish with dark distal tip, 

 tarsi black. Abdomen black with bright yellow cornicles which 

 are shaped much as in the foregoing species. (Fig. 45 B). 



Predominating color slate-black with orange yellow legs and 

 cornicles. There is the faintest suggestion of a light mid-dor- 

 sal line. (25-06). Orono, June 16, 1906. Willow twig. 



Nymphs (half grown progeny of foregoing). Predominat- 

 ing color dark reddish brown with conspicuous median dorsal 

 line of grayish white extending from front of head to cauda. 

 Ventral surface slightly powdery gray. Antenna light, clear, 

 with distal end dark. Legs with femora light clear, slightly 

 yellowish, tibiae dusky, and tarsi black. Cornicles yellow. 26- 

 06. Orono, June 16, 1906. Willow twig. 



Melanoxantherium smithiae Monell. A dusky reddish 

 species with hyaline wings, and pale pulverulent longitudinal 

 median line on abdomen, cornicles orange, shorter and more 

 bulging than in the three species preceding, accords with named 

 specimens of smithiae kindly given me by Mr. Monell. Figs. 

 43 C, 44 C and 45C, D. On Populus, migrating to Salix early 

 in June. 



Collection data for this species are as follows : 



4-04 (in part). Mixed collection of bicolor and smithiae. 

 Winged forms resting on cultivated currant (probably alighted 

 there temporarily only). Twelve taken in one hour. No pro- 

 geny present. May 26, 1904. Orono. 



15-04. Winged females. Willow. May 26, 1904, Orono.
