NATURAL SCIENCES OF PHILADELPniA. 55 



Androlyperus (g. n.). 

 A. fulvus, sp. n. 



Ovate, rather depressed, shining, fulvous ; head, scutellum, 

 inetasternum, legs, and antennae black ; thorax rather longer 

 than broad, coarctate behind, sides and base margined, disk 

 smooth ; elytra impunctate. L. .20. Coast Range, S. of San 

 Francisco (Horn). 



J* First ventral segment deeply foveolate, third and fourth 

 concave, each with a long linear process curving laterally over, 

 5-6 black, concave ; ejytra with a small brown spot before the 

 apex, margin deeply plicate and distorted at about f ; antennae 

 sub-serrate. 



This genus, by its general appearance, its antennoe, margined 

 elytra, etc, belongs in the vicinity of Luperus ; from which it is 

 alnindantly distinct by the last joint of tlie palpi, rather longer 

 than the preceding, acute, and by the prosternum distinctly visible 

 between the coxae, a character anomalous in the Galerucini, though 

 universal in the Halticini ; the posterior femora are in no way- 

 dilated. The remarkable sexual characters have suggested the 

 name emplo^'cd. 



Galeruga. The type of Geoffroy's genus was G. tanoceti, and 

 Adimonia is merely a synonym. I propose to restrict the name 

 Galeruca to Leconte's first group, in which the anterior coxal 

 cavities are closed, and the tibiae setulose. (These characters were 

 first used by Thomson in his Skand. Col.) 



Of the five species described, G. cribrata appears to me certainly 

 to be a variety of G. americana^ and G. himltata is somewhat 

 doubtful. 



Galerucella, g. n., differs from Galeruca by the open coxal cavi- 

 ties. It ma}^ be divided (as Thomson has done) into groups by 

 the relative position of the mesocoxae, which are distant in G. nym- 

 phese and sagittarise, and nearly contiguous in the other species. 



Galeruca cavicollis, Lee. 



Dr. Zimmerman's specimens were from Massachusetts and not N. 

 Carolina. A further series shows that it is not to be distinguished 

 from G. hsematica. 



G. marginella, Kirby. 



This certainly is the G. nymphese of Europe; G.punctipennis 

 Manuh., also is not, as far as I can see, specifically distinct.
