at the lower levels, but I also took them near Half Moon Lake 

 at an altitude of about 8000 feet. 



OrtJiotyliis cuneatiis Van D. Several specimens of this form 

 were taken on willows about Fallen Leaf Lake in company of the 

 preceding. 



Labopidea nigripes Rent. A small series of this very distinct 

 species were taken near the lower end of Fallen Leaf Lake in 

 July. 



Macrotylus mnlfipunctatus Van D. The uniciue type of this 

 interesting insect was taken by me near the lower end of Fallen 

 Leaf Lake July 17. Its pale surface, closely dotted with round 

 black points, will at once distinguish it from all the allied forms. 



Macrotylus lineolatus Uhler. A few examples of this form 

 were beaten from bushes about the lower end of Fallen Leaf Lake 

 late in July. 



Macrotylus infuscatus Van D. Taken with the preceding but 

 in greater abundance. Unfortunately I neglected to note the 

 food-plant of these species, but it may have been the willow which 

 grew in several localities about there. 



Microphylellus alpinus, new species 



Asjsect of Microphyhilus rubricaits Prov. but larger and darker; pieeoas 

 black with castaneous legs. Length 4..5 mm. to tip of membrane. 



Head nearly as in modestus, a little shorter when viewed from the 

 side; projecting below the eye for scarcely more than the width of the 

 eye. A^ertex without a basal carina. First joint of antennae a little 

 shorter than in the type species, surpassing the clypeus by about half its 

 length; second joint linear, distinctly incrassate, as thick as basal joint; 

 third and fourth together about as long as second, setaceous. Pronotum 

 proportionately shorter than in modestus ; humeral angles slightly promi- 

 nent, sides feebly sinuated and anterior angles well rounded; callosities 

 large, distinct, the impressed line strongly arched either side; the disk 

 minutely transversely wrinkled, sides subacute but hardly carinate. 

 Rostrum attaining apex of hind coxae, basal joint sini>assiug base of 

 the head. 



Color piceous-black, deeper on the head, pronotum and scutellum; 

 antennae uniformly concolorous; rostrum a little i)aler. Legs castaneous, 

 becoming piceous on the coxae, on the base of the femora, at least the 

 ])osterior, and on the tarsi. 



Described from one male example taken on the alpine meadows 

 on the western slope of Angora Ridge at an altitude of 8500 feet, 

 on July 26. This species is not typical of genus MicrophyhUus,
