tapering. Colour black ; clypeus, labrum, palpi, angles of the pronotum, 

 tegulas, a narrow band on all the apical abdominal segments and the 

 middle of the venter yellowisJi or orange colour. Legs black ; tips of the 

 coxje, trochanters, apical half of the femora and the bases of the tibife 

 yellow ; the four anterior legs are brownish, not black. Wings hyaline, 

 iridescent ; venation dark brown. 



Male : Length, 6 to 7 mm. The male differs from the female in 

 having the legs below the bases of the coxae orange colour ; the posterior 

 tibiae at the apex and sometimes above are infuscated. The trans- 

 verse radial of ihe male is quite often interstitial with the third transverse 

 cubitus. 



Type locality : Mountains near Claremont, California. One female 

 and six males collected by C. F Baker. 



Strongylogusler tibialis, Cresson. from Nevada, may belong to the 

 genus Prototaxonus. P. typicus differs from Cresson's description of ^. 

 tibialis in the yellow clypeus and labrum. 



Parataxonus lenis, Roh. — Taxonus lenis, Roh., Jn. N. Y. Ent. Soc,

On re-examining the type of this species I find it belongs to the genus 

 Parataxonus, MacG. 



Cryptocampus Baker i, n. sp. — Female: Length, 4.75 to 6 mm. 

 H.ad seen from the side broadest above the antennae, gradually narrowing 

 to the occiput ; seen from the front the occiput rounds up above the 

 orbits. Clypeus rather deeply emarginate, lobes rather broad, obtuse at 

 the apex. Supraclypeal fovea merging into the antennal fovese ; middle 

 carina strong; middle fovea deep, narrow, not closed above; the ocellar 

 babin not completely inclosed, the lateral walls the strongest ; lateral 

 ocellar furrows broad, shallow ; intraocellar fovea wanting ; frontal crest 

 not very strong, broken in the middle. The third and fourth antennal 

 joints about equal, perhaps the third is a little the shorter ; the apical 

 joint about the same length as the preceding, straight above, very slightly 

 rounded out beneath, the apex acute. Head not very closely or strongly 

 punctured ; scutellum shining, not nearly so closely punctured as the 

 mesonotum. Venation of both wings normal ; stigma broadest near the 

 base, gradually tapering to the apex ; claws deeply cleft, the inner tooth 

 the shorter. Sheath sna'siht above, gradually rounded from the rather 

 sharp upper angle below ; cerci s,lender, somewhat tapering, as long as
