Phyllotreta.] PHYTOPHAOA. 36.5 



the anterior coxae and the raesosternum a little longer than broad, 

 whereas in P. consobrina the prosternuui is strongly narrowed between 

 the anterior coxae, and the mesosternum is twice as long as broad ; in the 

 male, moreover, the fifth joint of the antennae only is dilated, and the 

 last ventral segment of the abdomen is impressed at apex with a small 

 fovea. 



P. punctulata, Marsh, (area. All.). A small species, of a uni- 

 colorous black colour with more or less distinct bronze reflection, which 

 is often almost absent ; the antennae have the base ferruginous, with 

 the exception of a portion of the first joint, which is dark ; this point 

 will at once distinguish it from the two preceding species, and from the 

 two following it may be easily separated by its much finer and more 

 confused punctuation. L. 1^-2 mm.

P. atra, Payk. Of a deep shining black colour, without metallic 

 reflection, antennae with the first four joints ferruginous, the base of the 

 first and the apex of the fourth being brownish ; thorax considerably 

 broader than long, with sides rounded, thickly punctured, the punctua- 

 tion being evidently finer than on elytra ; elytra long, separately rounded 

 at apex, rather strongly punctured, the punctures being arranged in 

 rather distinct rows towards base ; legs black, tarsi and knees lighter.

P. cruciferae, Groeze (pceciloceras, Com. ; obscurella, 111.). As anile 

 a little larger and broader than the preceding, which it very closely 

 resembles ; it may, however, be distinguished by the fact that the upper 

 surface always has a greenish or bluish metallic reflection and by the more 

 clear testaceous colour of the base of the antennas ; the thorax is nearly 

 as strongly punctured as the elytra, and the punctures of the latter are 

 disposed in more regular rows. L. 1|-2| mm.

P. vittula, Redt. A small species, oblong-ovate, rather depressed, 

 black with the thorax metallic greenish or coppery, and the elytra with 

 a yellow longitudinal band on each, which is feebly emarginate on its 

 outer margin, and on its inner side is somewhat strongly curved inwards 

 at base; it is also abruptly truncated or emarginate at shoulders, owing to 

 the black colour of the humeral callosity ; head with the front and
