Qalleruca scrijyta, Oliv., Ent., vi., p. 655, tab. 4, fig. 71. 



Var. B. Elytris flavis utroque vitta irregular! a vix infra 

 basin fere ad apicem extensa, j>lerumque ante apicem maculam 

 rotundatam flavam includente, nigra. 



Var. C. Elytrorum sutura vittaque submargiuali nigris. 



Var. D. Elytris flavis, obsolete nigro nebulosis. 



Long. 3— 3i lin. 



Hah. Cayenne ; Amazons. In most collections. 



Head not longer than broad, triangular ; clypeus with a broad 

 ill-defined longitudinal ridge ; antennae about three-fourths the 

 length of the body, filiform, the second and third joints short, the 

 third slightly longer than the preceding one ; the three lower 

 joints piceo-fulvous, the ninth and tenth white. Thorax about 

 one-half broader than long; sides parallel and slightly sinuate 

 from the base to beyond the middle, thence obliquely converging 

 towards the apex, all the angles very slightly produced, subacute ; 

 disk convex, impunctate. Elytra oblong, slightly dilated pos- 

 teriorly, convex, not depressed below the basilar space, distinctly 

 and rather closely punctured. 



Although the specimens that I have described as 

 representing the typical coloration of this species, and 

 those I have placed as varieties, at first sight appear 

 very dissimilar, they do not differ more than the type 

 and varieties of D. regalis, consentanea, and many others 

 of the present group. All the forms of Z). scripta agree 

 in the black anal segment of the abdomen and in the 

 coloration of the antennae, the ninth and tenth joints of 

 these latter alone being white. The type may be known 

 from its allies by the extreme base of the elytra being 

 narrowly edged with fulvous, by the absence of a second 

 subbasal spot (although specimens will possibly be found 

 in which this spot is present), and in the position of the 

 submedial one, which is placed much lower down on the 

 disk than is usually the case in 1). guttata and other 

 similarly coloured species.
