THE SAWFLY GENUS HOPLOCAMPA. 143 



Hoplocampa (Hoplocampa) califomica n. sp. 



Allied to hioculata Jlohwer, but may be separated by the table (p. 1 47) . 



Female. — Length 3.5 mm. Clypeus broadly, shallowly, angulately emarginate, 

 lobes broad, obtusely triangular; supraclypeal area convex, finely granular; anternal 

 furrows wanting, antennal fovese small; middle fovea elongate, shallow, not well 

 defined; ocellar depression small, distinct, not sharply defined; postocellar area well 

 defined on all sides; head and mesoscutum with small, separate, well-defined punc- 

 tui-es; antennae rather slender, third and fourth joints equal; sheath slightly c6ncave 

 above, slender, convex below from apex; cerci short, stout; stigma broadest near base, 

 strongly tapering to apex; transverse radius strongly oblique, in apical third of cell; 

 third cubital cell longer than the first and second combined. Black; clypeus, labrum, 

 mandibles (except piceous apices), orbits, occiput (except postocellar area), tegula?, 

 anterior legs (except coxse), intermediate femora, and part of posterior femora reddish- 

 yellow; posterior femora in part, most of four hind tibite, and tarsi black or brownish; 

 wings hyaline, iridescent; venation pale brown, stigma in part pallid. 



Paratopotypes show that the four hind legs may be mostly black, the posterior orbits 

 pale and the pale spots on the occiput reduced in size. 



Male. — Length 3 mm. Clypeus more obtusely emarginate than in female; third 

 joint shorter than fourtb; stigma not strongly tapering; hypopygidium narrowly 

 rounded at apex. Black; antennae, head (except interocellar area), margin of meso- 

 prescutum, lati, pectus, legs, and venter reddish-yellow; wings as in female. 



Type locality. — Suisun, Cal., March 10, 1910 (R. W. Braiiclier); 

 ei'i'ht females and one male. 



Type.— Cat. No. 13471, U. S. Xational Museum. 



Hoplocampa (Hoplocampa) maiiatti n. sp. 



(Plate XXIV, fig. 7.) 



Female. — Length 3 mm. Labrum short, broadly rounded; clypeus shallowly emar- 

 ginate, lobes broad, obtuse; supraclypeal area shining, convex; middle fovea broad, 

 not sharply defined, spreading over the antennae; antennal furrows interrupted by 

 the rather well-defined crest; ocellar basin represented by a small fovea in front of the 

 anterior ocellus; postocellar area scarcely narrowing apically; postocellar furrow 

 strongly arcuate; front shining, with separate, well defined, small punctures; antennae 

 slender, third joint distinctly longer than fourth; venation very like montanicola 

 (Plate XXVI, fig. 3) ; upper discal cell much exceeding the lower on the outer margin; 

 sheath as in Plate XXIV, figure 7; saw concealed. Color reddish-yellow; antennae 

 brownish; spots on mesoscutum, the metanotum, and the tergum (except apex) black; 

 tarsi dusky; wings hyaline, iridescent; venation pale brown, stigma yellowish pallid. 



Male. — Length 2.5 mm. Very like the female. Hypopygidium broadly rounded. 



Type locality. — Riley County, Kans. Four specimens collected 

 by Mr. C. Ij. Marlatt in April. 



Paratype locality. — Baldwin, Kans. Two females collected bv Mr. 

 J. C. Bridwell. 



Type.— Cat. No. 13477, U. S. National Museum. 



Hoplocampa (Hoplocampa) nevadensis n. sp. 



(Plate XXni, fig. 10; Plate XXIV, flg. 4: Plate XXV, fig. 4.) 



Female. — Length 4.5 mm. Labrum short, broadly rounded aj^ically; clypeus shal- 

 lowly, arcuately emarginate, lobes short, broad, obtusely rounded apically; supra- 

 clypeal area shining, not strongly convex; middle foveae poorly defined; antennal
