4 — Elytra red, coarsely punctured, each with two small black points arranged trans- 

 versely a little before the middle, the outer one on the median line and not quite 

 so basal ; metacoxal plates evenly parabolic, extending nearly to apical fourth. 



Length 4.8 mm. ; width 3.6 mm. Nebraska ophthalmica Muls. 



Elytra pale reddish-yellow, rather feebly punctured, each with a small oblique black 

 dash from the scutellum and two small subbasal spots, the inner the larger and 

 both oblique and uniting on the humeral callus, also with three widely isolated 

 black spots in a transverse line just before the middle, the inner more basal and 

 the outer very close to the margin, and two, very small, on a transverse line at 

 apical fourth, very near the margin and at inner third ; metacoxal plates extend- 

 ing nearly to apical fourth, obtusely angulate postero externally. Length 4.5 



mm. ; width 3.0 mm. California (Sonoma Co.) ovipennis, sp. now 



Elytra reddish-yellow, rather sparsely and moderately strongly punctate, each with a 

 longitudinal posteriorly pointed dash at each side of the suture from the 

 base, and two subbasal spots generally disconnected, the outer more basal and on 

 the callus, also with a transverse series of three rather large spots just before the 

 middle, the outer two generally connected, and two at apical fourth nearly as 

 large, the outer slightly more apical, transverse and very close to the margin ; 

 metacoxal plates rounded though a little more narrowly so postero-externally, ex- 

 tending nearly to apical fourth. Length 3.9-4.6 mm. ; width 2 8-3.5 mm -

5 — Elytra coarsely and closely punctured, each with a transverse basal spot acuminate 

 externally and extending from the suture to inner third, and a large triangular 

 subbasal spot involving the callus, also with a transverse uneven band near the 

 middle of the length, not interrupted at the suture, extending to lateral ninth or 

 tenth, the outer two-thirds straight and transverse, the inner third more basal and 

 posteriorly oblique toward the suture, and a transverse, somewhat bilobed spot at 

 apical fourth, equidistant from the suture and margin ; metacoxal plates but 

 slightly angulated, extending fully to apical fourth. Length 4.0 mm ; width

Elytra coarsely but rather less closely punctured, completely devoid of any trace of 

 basal or subbasal black spots, each with an irregulai transverse band just before 

 the middle, extending from inner sixth to outer third, and a small rounded spot 

 in the same line at outer fourth or fifth, also with an uneven transverse spot at 

 apical fourth, extending from inner fifth or sixth very nearly to the margin ; meta- 

 coxal plates parabolic, extending to apical third. Length 3.8 mm. ; width 2.7

Humeralis is said to be a variety of bipunctata by Crotch, and is 

 even omitted entirely from the Henshavv list, but my ample series of 

 each is perfectly homogeneous and without trace of any evidence of re- 

 lationship, the only variation from the normal being a small red point 

 in one example just behind the middle and near the side margin ; it is 

 smaller and more narrowly oval than bipunctata, has a differently 

 formed metacoxal plate, and inhabits a different geographical region. 

 The last five species of the table are related closely tofrigida, but they
