FAMILY CHRYSOMELID,*:. 131 



jn"t'on spots wliirh convtrgo tu cacli otlur, the outer the largest : parallel with the 



marginal line tliere are three large spots ; the remainder are seattered and smaller. 



The dots are (list rilmted somewhat irregularly, liut there is a tendency to arrangement 



in rows, as at the hase of the elytra and along the lines and larger spots. 



The insect IVom which the description is drawn is rather common, but it does not agree 



with the description uf the pliUddtlphica by Kiiiuv, who makes no allusion to the markings 



upon the thorax. The dilTerences I regard as sexual. 



In a few plates, I observe that the gmund color is too grecji : it should be pale, or 

 cream-colur. 



Chrysomela decipiens. 



Head, thorax, body and scutel dark green : <'lytra silvery wliite or white. Sutural line 

 thickened, and divergent near the scutel : the i>arallel and proximate lines wide, 

 divergent before, and narrowed towai\ls the apex; the second is shorter, and united 

 to it ; and the third is similar fo two heavv dashes united at their points, but instead 

 of being straight, they f >rm a ciuvc divergent from the other lines : these lines are 

 dotted. The shoulders are marked by a heavy dash or oblong spot : two other spots 

 are situated between the shouUIer spot and marginal line ; the upper roundish, and 

 the lower oblong. There are thirteen spots on e^ich elytrum, besides those already 

 desci'ibed, each of which is enclosed by a row of dots. Antenna?, palpi and legs rufous. 

 This species differs from the preceding, in having the thorax entirely of a dark green, 



anti also in the distrilmtidn and form of the lines and markings uj'on the elytra. 



CuRYso.MELA scALAuis. ( Plate xiv, fig. 10.) 



Ill ail, thorax, body and scutel dark green : elytra silvery while. Sutural line green, and 



extending to the base : a coalescing line falls into it just below the scutel, and forms 



with it an unequal stripe. There are two oblique dashes, which do not meet, on each 



elytnuu.The sp"t upon the shoulder is double, and prolonged in the form of a curve, 



and there is an .ther curved sjiot between the shoulder spots and sutural line. There 



are three coalescing spots upon the posterior flexure of the elytra. The other spots are 



arranged somewhat in two lines, j-arallel with the outer m.irgin of the elytra ; and 



there is a solitary d<it near the middle, and upon the outer margin of the elytra. The 



dots ai-e so arrangi<l ili:it lh<y follow the boundaries of the spots. Antenuir, palj'i and 



legs rust-brown. 



In the spei-imtn figured, a brownish color predominated instead of ilie silvery while : 



it may be a distinct vjiocles froin the .vr<//<(;/'.v, and is f'und in (he autumn upon variovis 



]>lauts.
