hairs many of which are encircled by a dark brown spot producing a dotted 

 appearance which is especially noticeable before the pseudosutural foveae ; 

 scutum clear, light gray with five brown lines, the outermost pair very broad, 

 dark brown, continuations of the lateral praescutal vittse ; inside these stripes 

 a pair of narrow lighter brown stripes; a delicate median brown vitta con- 

 tinued backward from the middle praescutal stripe; scutellum gray with 

 numerous long pale hairs which are surrounded by indistinct brown spots; 

 postnotum gray, the sides dark brown. Pleura clear light gray, indistinctly 

 and delicately lined and dotted with pale brown. Halteres short, pale, the 

 knob brownish just before the apex. Legs with the coxae gray ; trochanters 

 dull yellow ; femora dull yellow, their apices dark brownish black ; tibias dull 

 yellow, the apices narrowly black ; tarsal segments one and two brown, nar- 

 rowly tipped with black; remainder of the tarsi black; legs hairy. Wings 

 hyaline or nearly so, the costal cell dark brown ; a yellowish spot before the 

 arculus and before the radial cross-vein ; brown markings as follows : a large 

 blotch beyond the arculus; at the origin of Rs ; at the end of the sector con- 

 tinuing down to the cell ist Af o ; apex of the wings in cells 2d R^ and R2', 

 grayish brown seams on the crossveins and deflections of veins; a grayish 

 brown cloud in cell Cu continuing down into the tip of cell ist A; pale gray 

 clouds in the middles of the other cells of the wings. Venation as in plate 

 I, fig. 2; ^Ci ending just beyond the base of cell i?2 ; crossvein r not far from 

 the tip of /?i ; R2+3 shorter than the deflection of i?4+5 ; cell ist M^ hexagonal; 

 ilfi+2 beyond ni about equal to the basal deflection of Cui ; basal deflection of 

 C«, only a little longer than the prominent downward deflection of M3. 



Abdominal tergites with the first segment dark brown ; remaining tergites 

 light gray with a salmon caste ; a broad dorso-median dark brown line ; lateral 

 margins indistinctly pale ; a narrow sublateral brown line ; the entire surface 

 is densely spotted with prominent brown setigerous punctures ; sternites pale 

 grayish brown with an indistinct narrow dark brown median line and impressed 

 lines on each segment forming an irregular quadrate figure ; the surface with 

 abundant brown setigerous punctures ; caudal margins of the sclerites silvery. 



Habitat. — Eastern United States. 



Holotype, J, Framington, Connectictit ; June 7, 1914; Dr. R. W. 

 Marchand. 



The type is in the collection of the Boston Society of Natural 

 History. 



This interesting crane-fly is closely allied to L. alleni Johnson, (see 

 plate VIII, fig. I ) from which it may be separated by the appended 

 key. It is curious that there should be two such striking Limno- 

 philas found in the eastern states and overlooked by collectors until 

 within the last few years. This fly was handed to me for descrip- 

 tion by IMr. Johnson, to whom I am indebted for many other kind- 

 nesses and at his suggestion I dedicate the species to the collector,
