THE CANADIAN ENTOMOLOGIST 163 



Family Tipulidce. 

 Gonomyia (Gonomyia) mainensis, new species. 



Related to G. siibcinerea O. S.; thoracic pleura striped; abdominal tergites 

 dark brown; male hypopygium with the outer pleural lobe rather short with 

 its apex obliquely truncated; inner lobe bifid, with a posterior flattened blade. 



Male. — Length about 5 mm.; wing 5.6 mm. 



Head dark, discoloured in the type. Antenna broken. 



Pronotum clear light yellow. Mesonotal praescutum pale brown, with 

 three indistinct, dark brown stripes, the lateral margins light coloured; scutum 

 pale brown, the lobes dark; remainder of the mesonotum brown. Pleura light 

 yellow with two distinct, purplish brown stripes, the ventral stripe occupying 

 the mesosternum. Halteres very long and slender, pale, the knobs darkened. 

 Legs with the coxae dull brownish yellow, darkened on the base of the outer 

 face; remainder of the legs light brown, the tarsi darker. Wings with a faint 

 greyish tinge; stigma darker; veins dark brown. Venation: Sc rather long, 

 ending opposite about one-third the length of the radial sector; Rs very long, 

 straight ; i?2+3 very long, R-i correspondingly shortened ; deflection of Ri+h puncti- 

 form; cell 1st M2 with the inner end slightly narrowed; basal deflection of Cm 

 beyond the fork of M. 



Abdomen dark brown, the hypopygium yellowish. Male hypopygium 

 with the outer pleural lobe stout, hairy, slightly darkened toward the apex, 

 which is obliquely truncated and produced inwardly into a small tooth; inner 

 appendage bifid, consisting of a posterior flattened blade terminating in a hook, 

 with a single seta on its face; ventral lobe short, terminating in about two stiff 

 setae. Gonapophyses small, curved, strongly chitinized, in the unique type 

 unequal.

HoJotype. — cf , Fort Kent, Aroostook Co., August 29, 1913. Type in the 

 collection of the author. 



Gonomyia mainensis differs conspicuously from G. siibcinerea in its striped 

 pleura, venation, and, especially, the very different structure of the male 

 hypopygium. 



Limnophila (Ephelia) angustior, new species. 



Wings narrow, the brown markings confined to the vicinity of the veins; 

 pleurites of the male hypopygium with a tuft of long, yellow hairs at the apex; 

 outer pleural appendage with a prominent lateral tooth on the outer margin. 



Male. — Length 6.5 mm.; wing 7.5-7.6 mm. 



Female. — Length 8-8.4 mm.; wing 8.3 mm. 



Similar to L. superlineata Doane, differing as follows: 



Antennae dark brown throughout. Mesonotal praescutum without a 

 lateral brown line, the lateral stripes less distinct, the median stripe entire 

 Wings very narrow, strikingly different from those of either L. superlineata or 

 L. aprilina. Wings light grey with a dark brown and greyish brown pattern, 

 the costal markings relatively small, much narrower than the interspaces; the 

 markings on the disk take the form of narrow seams along the veins and cross- 

 veins; veins dark brown, Sc and R more yellowish. Venation: the super- 

 numerary cross- vein in cell M is inserted so that it lies beyond the end of the
