THE CANADIAN ENTOMOLOGIST. 241 



Prothorax a very little deeper than the vertex ; hind margin concave, 

 almost angled at the centre ; carinas very distinct ; colour uniform shiny 

 reddish brown. 



Legs brown, becoming lighter toward the distal end of the tibiae ; the 

 tarsi yellow ; spur wide at base and very finely serrate. 



Scutellum triangular, about twice as deep as the prothorax, sides 

 arcuate, apex a rather sliarp point, carina distinct, the lateral carinae 

 attaining the posterior margin, the median carina is obsolete toward the 

 apex ; colour shiny, reddish brown, with the margins and apex yellow. 



Elytra nearly twice as long as the abdomen ; colour smoky brown, 

 veins darker brown with dark dots along them. 



Tergum of the first two abdominal segments yellow, remainder of the 

 abdomen reddish brown. Genitalia, aperture of the pygofers large, oval, 

 wider than long ; ventral edge of the pygofers deeply notched, styles large, 

 broad, divergent from their base, following the curve of the pygofers to 

 the anal tube, a few long setae at their apical end. Length, including 

 elytra, 3.5 mm. 



Taken on reeds by the author in Renwick Swamp, Ithaca, N. Y., 

 July 20, 1908. Five specimens are before me, one of these shows much 

 more yellow on the vertex and front. Type in the author's collection. 



This species suggests the macropterous form of L. lineatipes Van 

 Duzee, but the colouring is different and, besides other minor differences, 

 the genitalia are decidedly unlike that species. 



Acko?-oti/e foveata, n. sp. 



Macropterous Ç . — Eyes oval deeply emarginate below to receive 

 the antennae ; colour gray. Vertex as wide as long, rounded before, ex- 

 tending a little beyond the eyes ; carinse distinct, except the posterior 

 median, which is weak ; posterior foveae deep ; colour yellowish brown, 

 lighter posteriorly. 



Front twice as long as wide, widest near the middle, sides gently 

 curving ; clypeo-frontal suture straight ; the median carinfe curved, follow- 

 ing the curve of the sides to the front ; just outside of each median carina 

 there is a row of pustules, six on each side, three near the vertex and 

 three near the clypeus ; between these two groups are two pustules on 

 each side along the outer margin of the front ; colour deep reddish brown. 



Clypeus shiny black with an indistinct carina. Second segment of 

 the antennae about one and one-third times as long as the first, covered 

 with pustules ; basal segment reddish brown, second segment yellowish 

 brown.
