on the costa, nearly parallel thence with the outer margin. S. t. line pale, a little 

 irregular, marked by a dusky preceding shade. There is a series of interspaceal 

 terminal lunules. Fringes concolorous. The claviform is vaguely traceable in some 

 examples, wanting in others. Orbicular large, irregularly ovate, oblique, paler than 

 the ground, the margins edged with darker scales. Reniform large, kidney-shaped, 

 paler than the ground, incompletely defined by a yellowish annulus and brown 

 marginal scales. Secondaries smoky whitish, paler at the base, the veins and a discal 

 lunule darker. Beneath yellowish-white. The disc of primaries smoky ; both wings 

 with an incomplete, diffuse median shade line and a smoky discal spot. E.\pands 

 1. 48-1. 68 inches =r 37-42 mm. 



Habitat: Brandon, Manitoba; Calgary, Canada, July 5-12 (F. 

 H. Wolley Dod). 



Two males and three females are before me at present ; others are 

 in the collection of Mr. Dod, who called my attention to the species. 

 In general appearance it resembles silens, but does not have the black 

 basal streak nor the blackish suffusion between the ordinary spots. On 

 the other hand it does have more complete, better marked median 

 lines. Attention once drawn to the species, its distinctness is clear 

 and its association is with basalis, from which, however, it differs ob- 

 viously in color.

Tribe II. Coccinellini. 



PVont coxal cavities closed ; base of antennre exposed ; melasternal and ventral 

 coxal lines distinct ; body loosely articulated, not very contractile ; usually rounded 

 in outline, sometimes oblong, never pubescent above. 



The technical definition of this tribe is given above ; it includes 

 those lady-bugs most commonly iiiet with, as the two-spotted lady- 

 bug {Atialia bipunctata') often found in houses, and the nine-spotted 

 lady-bug {Coccinelia g-noiata) which is abundant in gardens; most of 

 the species are about the size of these common representatives of the 

 group, round and convex. They feed on plant lice and are useful 

 insects. 



The genera are by no means strongly separated. The following 

 table is based upon that printed by Major Casey in this Journal (Vol. 

 VII, No. 2, June, 1899), simplified by the omission of the foreign
