Genus ANISOBAS Wesroael 



No American representative of this genus has heretofore been de- 

 scribed. The first of the follovring two new species is typical of the 

 genus, being very closely alhed to the genotype, Anisohas cingvla- 

 torins (Gravenhorst). The second species is somewhat anomalous. 



ANISOBAS NEARCTICUS, new spedes 



Female. — Length, 7.5 mm. 



Differs from cingulaiorius principally as follows: vertex arched 

 above level of top of eyes; eyes as long as width of vertex (not longer 

 as in cingulatorius) , parallel within; malar space distinctly shorter 

 than basal width of mandible; clypeal furrow represented by a broad, 

 shallow impression; clypeus convex, the apex slightly concavely trun- 

 cate; flagellum with 25 joints (31 in cingulatorius); propodeum 

 apically and laterally more strongly rugose; areola constricted 

 medially and there divided by two strong parallel rugae; apical carina 

 very high at apex of middle lateral area (area dentipara) ; dorsal 

 carinae of first tergite strong and extending well on to postpetiole, 

 the latter with a median impression; second tergite barely half as 

 broad at base as at apex; third tergite more than twice as wide at 

 base as long. 



Frontal white markings extending broadly on to face; scutellar 

 white spot smaller; hind tibia red, broadly fuscous at apex; otherwise 

 colored as cingulatorius. 



Type-locality, — Mount Desert, Me. (Southwest Harbor.) 



Type.—QB,t. No. 27680, U.S.N.M. 



One specimen collected by C. W. Johnson. 



ANISOBAS BICOLOR, new species 



Differs from both cingulatorius (Gravenhorst) and nearcticus Cush- 

 man in its entirely black thorax and entirely red abdomen. Appar- 

 ently not very closely related to any of the other European species. 



Female. — Length, 9 mm.; antennae, 6 mm. 



Head nearly as broad at temples as at eyes, in front view with 

 cheeks strongly rounded; distinctly punctate, densely so on face, 

 frons, vertex, and cheeks, sparsely so on temples and clypeus, the 

 last apically polished and unpunctate, broadly concavely sinuate 

 truncate; mandibles distinctly bidentate, ventral tooth somewhat 

 the shorter; malar space hardly as long as basal width of mandible; 

 eyes sUirhtly shorter than breadth of vertex, parallel within; antennae 

 stout, flagellum tapering toward apex; with 31 joints. Thorax 

 coarsely punctate, rather densely so on mesoscutum, scutellum, and 

 pleurum, more or less striately so on pleurum, sparsely so on meta- 

 pleurum; notauli and sternauh faintly indicated basally; scutellum 

 broad, weakly concave above, precipitous apically, with carinae
