 ish hairs, which are shorter and inconspicuous on basal half of disk, 

 densely, finely, shallowly punctate on basal half, sparsely, coarsely, 

 deeply punctate on apical half, impunctate along sutural margins on 

 apical declivity near apices ; apical declivity with sutural striae deeply 

 depressed and punctate in front of sutural teeth, the sutural margins 

 narrowly elevated, with two short, contiguous, costif orm teeth, one on 

 each margin at middle of declivity, the lateral margins thickened and 

 elevated; each elytron with two or three vague, costif orm callosities 

 along lateral margin of apical declivity. 



Abdomen beneath densely, finely punctate, densely clothed with 

 short, recumbent, yellowish-white hairs; last visible sternite slightly 

 projecting and subtruncate or vaguely emarginate at apex, with dis- 

 tinct lateral grooves.

Type locality. — Sauzalito, Calif., type in the Horn Collection in the 

 Academy of Natural Sciences of Philadelphia.

 Gatos (Hubbard and Schwarz). Santa Cruz Mountains (A. Koebele). West 

 Indian Gardens, Altadena. 



Hosts. — Coquillett (1892) recorded the adults of this species bur-

Head slightly convex, finely, rather densely punctate on front and 

 clypeus, with fine, longitudinal, parallel costae on occiput, rather 

 densely clothed on front with very long, erect, brownish hairs, which

 slightly depressed at middle along posterior margin; clypeal suture 

 depressed at middle, obsolete at sides. 



Pronotum slightly wider than long, widest at middle; sides regu- 

 larly, broadly rounded, with a small, broad tooth at apical angles; 

 posterior angles broadly rounded ; surface sparsely clothed with short, 

 recumbent and erect, inconspicuous hairs, with numerous very long, 

 erect, brownish hairs along sides on apical half and along anterior 

 margin, very sparsely, finely punctate on basal half, coarsely, sparsely
