for the tibipe, which are quite slender. First four joints of tarsi small, 

 sub-equal, terminal joint nearl}- as long- as the four united. 



This genus possesses very distinct characters by which it may be sepa- 

 rated from all others, viz : Tlie sliort, broad form ; the thorax, so wide at 

 base and narrow in front, with the antennal fossae dividing its lateral mar- 

 gin ; the mouth parts covered, except the labrum, by the prosternum ; 

 the widely separated mesocoxae, and finally the clothing, consisting of 

 large or small variegated scales. 



Tlie following table will enable us to recognize the species : 

 Antennae 11-jointed ; club 3-jointed. 



Eyes emarginate ; scales coarse, large, triangular, as wide 



as long. Antennal club oval scrophulariae. 



Eyes entire ; scales fine, not triangular, three times as long 



as wide. Antennal club oblong varius. 



Antennae 8-jointed ; club 3-jointed. 



Eyes entire, scales small, triangular museorum. 



Antennae 5-jointed ; club of a single very long joint. 



Eyes entire, scales small, triangular claviger. 



A. scrophularice Linn. Ovate, moderately convex, black, clothed with 

 large, triangular, black, white, and orange-red scales. Elytra marked by 

 a sutural longitudinal band and apical spot of orange-red scales and 

 two transverse bands and basal spots of white. Head black, coarsely 

 punctate, thickly covered with black scales, a few orange-red scales 

 around the eyes and on clj^peus. Ej-es emarginate in front, not very 

 prominent. Antennae black, 11-jointed, terminated by a broadly oval 

 3-jointed club, which is as long as all the preceding joints united. 

 Thorax black, coarsely punctate, disc covered M'ith black, sides and base 

 with white and orange scales. Scutellum hardly visible. Elytra black, 

 mostly covered with black scales, but the suture is broadly orange with 

 three equi-distant lateral projections of the same color, the first tw.o of 

 which join sinuous white bands ; the posterior is obscurely connected with 

 an apical orange spot ; usually a distinct basal white spot. Body beneath 

 black, covered with white and orange scales. First abdominal segment 

 with two naked hollows, on each side of base, to receive the posterior 

 femora, last four with lateral black spots ; terminal segment with a large 

 median quadrilateral black space. Legs black or rufous, femora clothed 

 sparsely with white and yellow scales. Length .09-. 14 inch ; 2.2-3.5 mm. 

 (Figs. 66, G9.) 



A common and widely distributed species, to be recognized by tlie emar- 

 ginate ej'es, large scales, and broadly oval antennal club. The ornamenta- 

 tion varies greatly in color and arrangement. The entire color of the 

 upper surface may be altered, the orange in the sutural band may be 

 replaced by white, and the transverse bands may become indistinct and 

 small, or again .large and confluent. 



Two varieties dependent on these changes are to be found in our fauna.
