5_ Tarsal claws with a large subquadrate internal tooth at base 6 



Tarsal claws cleft within 21 



6 Scutellum very minute ; body small, rounded, pale with black spots, the meta- 



coxal plates without an oblique dividing line ; prosternal process very narrow, 

 strongly bicarinate to apical third or fourth ; antennae with a narrow, obtri- 

 angular club, the last joint rather longer than wide ; claws slender, the basal 

 tooth but slightly developed transversely. Africa *Micraspis 



Scutellum not extremely minute or punctiform ; basal tooth of the claws large and 

 conspicuous 7 



7 — Epistoma truncate or subtruncate at the apex of the coriaceous or semi-corneous 

 margin ( Subtribe CocciNELL^ ) 8 



Epistoma deeply sinuate. ( Subtribe Cydoni.-k)... 18 



$ — Metacoxal plate divided by an oblique line joining the bounding arc at about its 

 middle point, forming an angulate inner plate 9 



Metacoxal plate not or only partially divided, the oblique line either wholly obsolete 

 or feeble, or, when more distinct, not joining the boundary curve posteriorly. .14 



9 — Ublique line meeting the bounding curve at a point which is but little beyond the 

 middle of the segment ; body oval, rather depressed, with coarse and unequal 

 punctuation, the side margins abruptly but very finely reflexed ; prosternal process 

 concave along the axial line ; mesosternum with a very small, circularly rounded 

 median notch ; antennal club large, obtriangular, compact, 'he last joint nearly 

 as long as wide and obliquely truncate. ... Agrabia 



Oblique line meeting the bounding curve at or very near the hind margin of the seg- 

 ment 10 



10 — Mesosternum transversely truncate anteriorly ; body strongly convex, oval, more 

 or less finely and equally punctate, the side margins very finely reflexed ; pro- 

 notum solidly black, with a more or less subquadrate pale spot at the apical 

 angles ; hind angles rather narrowly rounded Cocci ne I la 



Mesosternum broadly sinuate at the anterior margin ; side margins more broadly re- 

 flexed II 



II — Pronotum solidly black, with broad pale side margins ; body oval, rather strongly 

 convex, the elytra sometimes having a transverse subapical plica ; punctures 

 fine and subequal. Palasarctic * f*tychanatis 



Pronotum variegated throughout its extent with black and pale markings, or pale 

 with small black spots 12 



12 — Body globularly convex and very broadly rounded, minutely and equally punc- 

 tate, the pronotum pale with small black points, the elytra with transverse series 

 of spots on a pale ground, or, by extension, of pale spots on a dark ground ; 

 prosternum with two fine carinas converging anteriorly and extending slightly be- 

 yond the middle. Africa * Stictoleis 



Body moderately convex or somewhat depressed, oval in form ; pronotum pale, varie- 

 gated with black 13 



13 — Elytral punctures strong and unequal ; prosternum not bicarinate. 



Neoharmonia 



Elytral punctures finer and equal; prosternum with two fine approximate carinas, con- 

 verging slightly in front and extending to about the middle of the length. Africa.
