base and sides of the large basal segment, as well as the venter entirely, 

 more or less clothed with black pubescence. Length 4 J — 7 lines. 

 Eight specimens. 



9. Mutilla fuivohirta. n. sp. 



Black ; head, thorax and abdomen above, except base, densely clothed with 

 bright fulvous pubescence; wings blackish. 



Male. — Head black, coarsely punctured, with long black pubescence, 

 mixed with fulvous on the vertex ; eyes small, rounded, entire and 

 convex; antennae about as long as the head and thorax, black, serice- 

 ous. Thorax coarsely punctured, black, the upper surface clothed with 

 a long, dense, bright fulvous pubescence, on the sides and beneath it 

 is black; metathorax broad, abrupt behind, rounded on the sides, re- 

 ticulated with coarse punctures, and thinly clothed with fulvous pubes- 

 cence. Wings ample, blackish, much paler about the middle ; the cells 

 much as in M. monticola, except that the third submarginal cell (which 

 is also very indistinctly denned) is more narrowed beneath, and the 

 second submarginal receives the first recurrent nervure more towards 

 the middle. Legs entirely black, with black pubescence. Abdomen 

 ovate, black, shining, closely punctured and clothed with black pubes- 

 cence ; apical margin, sometimes the apical half of the large basal seg- 

 ment, and all the other segments above, clothed with a dense bright 

 fulvous pubescence ; beneath entirely black. Length 5 — 6 lines ; ex- 

 panse of wings 9 — 11 lines. 



Nine specimens. The pubescence on the upper surface of the head, 

 thorax and abdomen varies from ochraceous to ferruginous, but gene- 

 rally it is bright fulvous. This may be the % of M. callfornica.

 golden pubescence ; eyes small, round, entire and convex ; antennae 

 black, subsericeous. Thorax black, with black pubescence ; the pro- 

 thorax above, the mesothorax and scutellum, rufous, clothed with long 

 golden pubescence ; metathorax black, rounded behind, with large, 

 coarse punctures and sparse black pubescence ; tegulae black, punc- 

 tured. Wings dark fuscous, paler about the middle ; marginal cell 

 large, rather long, rounded or somewhat pointed at tip, and exceeding 

 the tip of the third submarginal cell; three distinct submarginal cells, 

 the first nearly as long as the marginal ; the second broad beneath, 

 much narrowed towards the marginal, and receiving the first recurrent
