stigma fuscous, the ne-rviires darker; the basal abscissa of tlio rarlins 

 about one-fourth shorter than the second, the apex -wide, broaillv round- 

 ly dilated in the middle. Central areae of metanotuni slightly longer 

 than wide, wider at the apex on the inner than on the outerside, the 

 sides at the base rugosely puncitured; the middle areae of the s°.cond 

 row are square, the outer longer than wide; the apical slope is aciculat- 

 ed with some obscure striae around the top. Metaplcurae on the upper 

 apical half with some stout irregular longitudinal striae, the rest 

 smooth. Proplenrae smooth, irregularly wrinkled at the base. Mesopbu- 

 rae strongly closely punctured. Pygidium with a smooth keel down 

 the middle, extending from the base to the apex and of equal thickn- 

 ess, the rest smooth on the inner, strongly punctured on the outer half. 

 Apex of fore tibiae and the greater part of the tarsi rufous. ^Nfale. 

 Bength 4.5 mm. Ormsby county. Nevada (Baker). 



This is the smallest of the North American specir-s. It lias the yellow 

 apical ,line on the clypeus narrower than it is in ind'rtnfdui. from which 

 it differs furtheir in the keel on the pygidium running froin the base 

 to apex, not on the apical half only; it differs also in the fuscous 

 stigma and in the apical abscissa of the radius being broadly rounded; 

 the pubescence on the head and thorax is less dense and the third 

 transverse cubital nervure lis straight obique in one slope, not angle*} 

 below SuS in intermedia. 



A NEW MUTILLID NEAR BRACIIY CTSTTS FROM CALTFORNTA 

 C. F. BAKBB 



At Claremont, California T captured, flying by day, a single specimen 

 of a most remarkable small shining black mutallid, a male, which in 

 many features was like Brachycistis and which possessed a most remar- 

 kable superficial resemblance io a figitid. A very high, arched meson- 

 otum, very broad first abdominal segment, and very deep second seg- 

 mienit, ogives it a habitus quite distinct from that of Brachiichtis. Its 

 wing venation is, moreover, quite peculiar. The stigma is very large and 

 dark. The nmrginal cell is extremely small, very na-rrow, extends from 

 apical third of stigma to costal margin and is not appendiculate. Thi? 

 single submarginal cell is subquadrangular but much broader apieally. 

 There are two discoidals the first rectangular and but little longer than 

 broad. The veins are mostly nearly colorless. The traT'sverse median 

 between first and second segments is scarcely evident as viewed from 

 nervure is nearly interstitial with the basal vein. The constriction 

 above, but from the side the depth of second segment accentuates the 

 ventral simis. The prothorax is very short^a na,rrow band from above. 

 The ocelli are minute, not at all enlarged, the hind ocelli being about 

 as far from eves as from each other.
