THE CANADIAN ENTOMOLOGIST, 367 



PJirofitosoma atriim, n. sp. — Body black, with the tegulae, a fine Une 

 on the collar, and all the legs beyond the apical third of the femora, white; 

 the apex of the posterior tibiae and the tarsi infuscated ; the antennal 

 furrow below the lateral ocelli broad and coarsely punctured ; the frontal 

 ridge wanting and the antennal fovea and ocellar basin continuous ; the 

 third segment of the antennae as long as the fourth and fifth together. 

 Length, 6 mm. 



Habitat. — Ames, Iowa. E. D. Ball, collector. 



Phrojitosoma JVortoni, MaqG. — This species was described in the 

 Canadian Entomologist, 1894, XXVI, 324, as a new species of Caliroa. 



Phrontosoma Daeckei, n. sp. — Body black, with a rufous spot covering 

 the collar and mesonotum ; the tegulae and legs beyond the apical third of 

 the femora, white; the third segment of the antennae as long as the fourth 

 and fifth together ; the frontal ridge distinct and unbroken, the antennal 

 fovea and the ocellar basin therefore not continuous ; the antennal fovea 

 as large or larger than the ocellar basin, and extending through the 

 hypoclypeal area ; the triangular depression behind the anterior ocellus 

 not extending to the antennal furrow. Length, 7 mm. 



Habitat. — Glenside, Mtg. County, Penn. E. Daecke, collector. 



P/iro?itoso?fia collar is^ n. sp. — Body black, with a rufous spot covering 

 the greater part of the prothorax and the mesonotum ; the third segment 

 of the antennae hardly as long as the fourth and fifth segments together ; the 

 frontal ridge distinct and unbroken ; the antennal fovea long and distinct; 

 the ocellar basin almost wanting ; the triangular depression behind the 

 anterior ocellus distinct and extending to the antennal furrow. Length, 

 7 mm. 



Habitat. — Ames, Iowa. E. D. Ball, collector, 



Emphyius cifictipes, Nort. — Many writers since the time of Norton 

 have considered this species as the same as the European Emphytus 

 cinctus, Linn., while the coloration is practically identical, the form of the 

 frontal area, the shape of the saw-guides, and the dentation of the saws is 

 entirely diff"erent, and I believe that Norton's species should be recognized 

 as distinct. 



Parataxonus, n. gen. — Front wings with the radio-medial cross-vein 

 always present ; the second abscissa of Cu always shorter than the free 

 part of M4; the hind wings with both the free part of R^ and the transverse 

 part of M.2 wanting ; the posterior metatarsus never longer than the four 

 following segments together; the claws with a large erect tooth at middle. 

 Type, Taxofius multicolor, Nort.
