COLEOPTERA. 557 



The maxillary palpi of some are thicker and truncated at the ex- 

 tremity. 



Of these there are some in which the two last joints of those palpi 

 are united and form a truncated club; the last is shorter than the pe- 

 nultimate, and is either transversal or in the form of a very short 

 and truncated cone. 



% 

 Phyllocharis, Dalm. 



Where there is no mesosternal projection(l). 



Doryphora, Illig. 



Where the mesosternum, on the contrary, advances in a point or 

 in the manner of a horn. The species of this subgenus are proper 

 to South America(2),- those of the preceding one inhabit New Hol- 

 land and the island of Java. These, of which there are but few, dif- 

 fer from the preceding in their more elongated and much less ele- 

 vated body, and in their antennae, the first joints of which are pro- 

 portionally shorter, thicker, and more rounded at the extremity; the 

 second is almost globular and scarcely shorter than the third. 



Two species are found in Spain which should form another sub- 

 genus Cyrtonus, Dalm. As in Phyllocharis, there is no mesosternal 

 projection, but the joints of the antennse are proportionally longer 

 and more obconical; the body is more convex, and the thorax higher 

 transversely and pulviniform, or rounded in the middle, whilst its 

 surface is plane or on a level in the preceding subgenera(3). 



Another subgenus, 



Paropsis, Oliv. Notoclea, Marsh, 



Of which all the species are exclusively proper to New Holland, 

 is distinguished from all the others of this family by the maxillary 

 palpi, the last joint of which is much larger and securiform(4).

(3) Chrysomela rotundata, Dej., arid another very analogous but striped spe- 

 cies. I have received from Dr Leach a Chrysomela allied to the Doryphorse, in 

 the male of which the antennae present but eight joints, the two last forming a 

 club. It constitutes his genus Apamxa. The Chrysomela badia of Germar ap- 

 pears to form another. 



(4) See Oliv., Col., V, 92; but we must take away the P. flavicans Chryso- 

 mela flavicans, Fab. which is a true Chrysomela. See also the Monograph of 

 the same genus, but under the name of Notoclea, published by M. Marsham in the 

 Transactions of the Linnean Society.
