Type locality. — Orange, Calif. 



Host. — Rhus integrifolia (Nuttall) B. and H. 



Type material. — Holotype and one paratype, U.S.N.M. No. 56408. 



The type series was collected October 24, 1934, by W. Ebeling. 



STENOCLYPTUS CEANOTHI, new species 



Female. — Piceous-black, subopaque; 1.68 mm. long, 2.68 times as 

 long as wide; similar to rhois in habitus but with finer surface struc- 

 tures more or less hidden by an incrustation. 



Frons convex above, weakly concave between eyes, finely, closely 

 punctured, with rather coarse, moderately long hairs directed dorsad 

 on most of surface, directed oracl from epistoma so as to veil the mandi- 

 bles. Eye rather small, short ovate, inner line entire, facets moderately 

 small. Antenna very similar to that of rhois, but with hairs of scape 

 more abundant and longer. 



Pronotum about as long as wide, widest one-third of distance from 

 base, posterior outline nearly straight, posterior angles strongly 

 rounded ; sides strongly arcuate from base to rather narrowly rounded 

 anterior margin, which bears two strong serrations; summit high, 

 lighter in color, distinctly behind middle ; anterior area coarsely, rather 

 sparsely asperate on an ovate area, with hairs coarser and more con- 

 spicuous than in rhois; sides and posterior disk subopaque or feebly 

 shining, reticulate, with small, shallow punctures (often concealed 

 by incrustation) , hairs coarser than in rhois, short and inconspicuous 

 except on posterior margin and in impression behind summit. 



Elytra slightly wider than pronotum and 1.76 times as long, 1.68 

 times as long as wide ; sides subparallel on anterior three-fourths, very 

 broadly, subtruncately rounded behind; surface opaque owing to an 

 apparent incrustation which conceals most of the strial punctures; first 

 stria feebly impressed, only near declivity, the others not impressed ; 

 interspaces with surface concealed by incrustation, but indicated by 

 rows of short, fine hairs, longer and thicker at sides and behind. 

 Declivity rather steep, suture elevated, more strongly posteriorly, with 

 a sulcus at each side, lateral convexities rather high; higher than 

 suture above, surface incrusted in type but one paratype showing sur- 

 face subshining, finely rugosely punctate; hairs rather sparse, stouter 

 than in rhois. 



Fore tibia with sides sinuate, subparallel as in Hylocurus, outer 

 edge not serrate, terminal mucro long, somewhat curved, distal end 

 oblique and armed with three submarginal teeth. 



The male is unknown.
