are distinct among themselves and therefore probably not mere varietal 

 forms of that species. Annectans is quite unaccountably placed in 

 Coccinella by Crotch. Ludovicce of Mulsant, cannot be identified and 

 has a different type of pronotal ornamentation from any noted in the 

 table. The Coccinella disjuncta of Randall, is evidently an Ada/ia, 

 allied to frigida, but I have not been able to identify it ; it must re- 

 semble ornate/la very closely. 



Agrabia, gen. now 

 The species given be-low, together perhaps with the Mexican viridi- 

 pennis Muls., is the only known representative of this genus, which 

 resembles Ada/ia in the oval, moderately convex form of the body. 

 The side margins are exceedingly narrowly and finely reflexed : — 



Oval, moderately convex, pale rufo-testaceous throughout above and beneath, except 

 the elytra which are bright blue, sometimes with a feeble greenish tinge, the 

 side-margins very narrowly testaceous from the humeral angles to apical four- 

 fifths, where the pale margin is inwardly dilated, forming an elongate, internally 

 arcuate spot, which narrows and disappears completely very near the sutural 

 angles ; punctures strong and rather close-set, somewhat unequal. Length 5.5 

 mm. ; width 3.9 mm. New Mexico cy anoptera Muls. 



The description of Crotch is very inexact, especially in regard to 

 the antennae, which are not unusually short for the Coccinellini, and 

 the mesosternum, also in stating that the body is "subhemispherical." 



Coccinella Linn. 



This genus is still a receptacle for many discordant elements ; 

 venusta, which is assigned to it by Crotch (Trans. Am. Ent. Soc, 

 1873), is the type of a distinct genus, named Neohdrmonia in the table, 

 and, in the "Revision," picta belongs to Cleis and not to Uarmonia, 

 where is was subsequently placed, and cyanoptera to Agrabia and not 

 to Harmonia. Even as restricted in the present essay, however, the 

 genus is still a large one and our species may be conveniently separated 

 as follows : — 



Elytra without trace of a basal fascia, the spot on the callus wanting or moderately 

 developed ; body large, usually broadly oval or elliptic 2 



Elytra with a transverse subbasal fascia, sometimes disintegrating ; body large, 

 strongly convex and broadly oval , 11 



Elytra with a transverse subbasal fascia, sometimes disintegrating into three spots; 

 body smaller and generally more narrowly oval, polished ; pronotum with the 

 apical margin and a subquadrate externally broader spot at each apical angle pale 

 in color 12
