36 THE CANADIAN ENTOMOLOGIST. 



Glyptina, Lee. 



Species of this genus will almost certainly be found in Canada. They 

 have the elytral punctuation disposed in rather regular strire, while in 

 Longitarstcs the punctures are confused. Otherwise there is considerable 

 similarity between the two genera, as far as aspect is concerned. 



Phyllotreta, Foudras. 



Contains a few species only, the Canadian ones all being of a piceous 

 colour, more or less aeneous or greenish, shining, the elytra marked with 

 yellow stripes or spots. (P. vittata, fig. 8.) Often injurious by their 

 great abundance; they are to be seen on the leaves of horse-radish, wild 

 mustard, and various allied plants, wild or cultivated. It should be noted 

 that the record for lepidula ought to be carefully verified, since the species 

 is Californian. P. sinuata has been included in the table, though not 

 actually known to occur in Canada. 

 A. Fifth joint of antennce much enlarged {$,) ox longer than the sixth 

 ( ^ ). Elytra usually vittate, rarely spotted. 



b. Elytral vitta simple, narrow, nearly straight, but incurved 



at the apex. .08-10 in lepidula^ Lee. 



bb. Elytral vitta sinuous, more or less dilated or appendicu- 

 late at ends. 

 „ ^ Vitta incurved at base, approaching the scutellum ; in-

termediate portion sometimes wanting, leaving the 



apical parts in the form of spots (fig. 9a.). .08 in. . .vittata, Fabr. 



Vitta parallel with suture at its basal half. .10 



in. (fig. 9b) simiata, Steph. 



AA. Fifth joint of antenn* not modified ; fifth joint not 

 longer than sixth in either sex. Piceous, not 

 metallic. Each elytron with two oval yellow 

 spots, one humeral, the other near the apex. 

 .08-. 10 in hipustulaia, Fabr. Fig. 9. 



Mantura, Steph. 



Represented by M. florida?ia, Cr., an oval, somewhat elongate, 

 moderately convex beetle, of a brownish colour, faintly bronzed above ; 

 thorax without transverse antebasal impression, longitudinal basal im- 

 pressions deep and triangular. Elytra indefinitely paler at apical third. 

 Legs reddish, hind femora darker, each of the tibiae with a terminal spur. 

 In colour this species somewhat resembles Cripidodera modeeri, Linn.,
