Adalia, Muls. 



Two species are found in the Canadian lists ; they are similar in out- 

 line to Coccinella, but less convex. Being very variable in colour, they 

 are likely to make trouble, but may be separated thus : — 



Elytra uniform yellowish red or with transverse fasciae of small black 



spots in varying number, .t8 in .frigida, Schn. 



Elytra yellowish-red with a rather large discoidal black spot, 



.19 in bipunctata, Linn. 



Elytra black, humeral angles, or entire basal region, and a smaller 

 post-median spot red var. hunter alls, Say. 



Harmonia, Muls. 



The species of Harmonia are very troublesome to define by descrip- 

 tion, but are comparatively easily recognized after a short acquaintance. 

 H. i2-maculata is easily known by its convex form and 

 resemblance in coloration to Megilla macttlata, while the 

 oblong-oval form and peculiar markings (see Fig. 48) of 

 If. picta render the more typical specimens easily known. 

 H. 14-guttata, while of somewhat the same form as 21- 

 maculata, may be easily separated from it by the dark 

 ground colour with lighter markings. The differences may 

 be stated, then, as follows : — 



Elytra testaceous or pinkish, with large black spots ; one common 

 scutellar, one common at about three-fourths, and, on each elytron, 

 one humeral, two medial, one post-medial, and one triangular 

 apical. Thorax with two very large black spots. Form hemi- 

 spherical, .22 in , i2-maculata, Gebl. 



Elytra light red with pale spots, or black with red spots, normally 

 seven on each, but sometimes reduced to two. Punctuation un- 

 equal. Thorax with front and hind margins pale, often also with a 

 medial line and spot near the hind angles, . 23 in. . . 14-guttata, Linn.
