1?UNGUS GNATS OV NORTH AMERICA. I37 



black, antennje, palpi and hypopygium fuscous, clasper (Fig. 

 133). Antennae less than 3-4 length of the body in dried speci- 

 mens. Coxse and legs dusky yellow, tarsi darker, hind tibia 

 and tarsi subequal. Wings grayish hyaline, veins dark (Fig. 

 236). Halteres brown with yellowish petiole. 



Female. Colored like the male, hind tarsus slightly shorter 

 than the tibia, antennae about half the length of the body in 

 dried specimens; lobes of the ovipositor dusky (Fig. 144). 

 Both sexes, Montreal, Canada ; Ithaca, N. Y. ; Orono, Me. 

 Larvae in manure. Treesbank, Manitoba (N. Criddle.) 



Var. a. Male and female. As above but petiole of the cubitus 

 only .6 as long as the basal section of M, and halteres, coxae 

 and legs- brighter yellow. Ithaca, N. Y. ; Black Mts., N. C. 

 (W.B.) ; Kas., and Col. (Tucker). 



On examination of a slide of type material proves my speci- 

 mens to be this species. Dr. Lintner's specimens were taken 

 in a mushroom cellar at Albany, N. Y. 



47. Sciara caldaria Lintner. 



Rept. State Ent. X. 398. 1895. . 



Male. Length 2.5 mm. Head, thorax and abdomen black, 

 the mesonotum shining; hypopygium black, in structure like the 

 preceding species ; antennae and palpi fuscous, the intermediate 

 flagellar joints nearly 3 times as long as wide, antenna over 

 3-4 as long as the body in dried specimens. Coxae and legs 

 brownish, the hind coxae and sometimes also hind femora, dark 

 brown ; tarsi fuscous ; hind tibia and tarsi subequal. Wings 

 grayish hyaline, veins dark. Halteres fuscous. 



Female. Similar to the male in coloring, antennae shorter; 

 terminal lobe of the ovipositor more elongate than in 5. copro- 

 phila "Boise, Idaho." Captured in a green house. 



An examination of a slide of the type material does not 

 reveal any structural differences between this and the foregoing 

 species, excepting that the antennae in this appears to be a trifle 

 longer. 



Var. a. Similar to the above, but antennae distinctly longer 

 than in S. coprophila and the anterior wing veins heavier (Fig. 

 237). Ithaca, N. Y.
