confirmed somewhat by the antennae, which are rather long, slender, 

 with very feebly dilated 3-jointed club having somewhat elongate and 

 loosely connected joints. The anterior coxae are not unusually widely 

 separated, and the presternum is not prominent at the middle of the 

 apex ; the mesosternum is broadly sinuate. The genus seems to differ 

 from Mysia, the type of which is oblongoguttata, in the more narrowly 

 reflexed margins, very fine punctuation and polished surface ; it has 

 but little affinity with Anatis. Our species are the following : — 



Pronotum without a well-defined discal dai-ker area 2 



Pronotum with a large trapezoidal median dark area, which is well defined externally.. 3 

 2 — Pronotum pale yellow, with a feeble red-brown clouded basal spot at lateral fourth 

 and a small nubilate V-shaped spot just before the middle on the median line, 

 also with a feeble disintegrated discal cloud near each side ; elytra yellow, each 

 with three fine incomplete and interrupted subequidistant longitudinal vittce of 

 pale red-brown Length 7.0 mm.; width 5.7 mm. New Mexico (Fort Win- 

 gate) interrupta, sp. now 



Pronotum pale yellowish-brown, without maculation, except a feeble trace of the two 

 basal clouded spots of the preceding ; elytra similar in color, with three very 

 feeble incomplete nubilate vitta? on each, the two inner uniting near the apex and 

 broader, the outer narrow and almost completely obsolete. Length 6.7 mm.; 



with 5.4 mm. California horni Cr. 



3 — Elytra uniformly pale yellow-brown, sometimes slightly paler along the base and 

 externally, rarely with feeble trace of two brown vittce uniting near the apex at the 

 middle of the width ; pronotum in the male black, with broad yellow side mar- 

 gins, obliquely subrectilinear internally, inclosing a detached central black spot and 

 with barely a trace of a small pale spot before the scutellum, the apex rather 

 broadly yellow in a straight line slightly broader at the middle ; female similar 

 but with the dark area pale brown with clouded blackish lateral edges, the pale 

 apex not dilated at the middle. Length 6.4-7.2 mm.; width 4.9-5.5 mm. 

 Canada, New Jersey, Indiana and Texas (Galveston); \notans Rand.]. 



pullata Say 



Elytra pale, with broad irregular longitudinal markings 4 



4 — Pronotum black, obliquely yellow in outer fifth, the pale margin inclosing a small 

 internally angulate black spot just behind the middle and equidistant from the 

 margin and central black area, which is bordered broadly with yellow at apex, 

 the margin dilated posteriorly along the median line for a short distance, also 

 with a small pale bifurcate spot before the scutellum ; elytra pale, with a broad 

 black subsutural vitta from the base for three-fifths, uniting broadly at base with 

 a short broad median vitta, which extends one-fifth, with a triangular black spot 

 in the same line just before the middle and continued again as a broad vitta 

 from three-fourths to seven-eighths, the posterior extremity being in line with the 

 subsutural vitta, also with a narrow external vitta from one-third to three-fourths ; 

 suture finely black throughout, a whitish basal spot at each side of the scutellum ; 

 under surface and legs black. Length 6.6 mm.; width 5.3 mm. Lake Superior.
