202 PERCY SLADEN TRUST EXPEDITION 
Paracymus alluaudianus is closely allied to the Madagascan and Hast African 
Paracymus chalceus Régimbart (Ann. Soc. ent. France, Ixxi. 1903, p. 32), a cotype of 
which I have been able to study through the kindness of M. Lesne. Its upper and under 
sides are coloured similarly to those of allwaudianus, but it is a trifle larger, and at once 
distinguished by its much finer and less dense punctuation. This difference is very 
noticeable when the two are viewed side by side. In chalceus (as in allwaudianus) the 
elytral punctures are simple and circular. 
Among the European species, w@neus Germar is separated from scutellaris Rosenh. and 
punctillatus Rey by having an elevated longitudinal lamina on the mesosternum behind 
the tooth and transverse crest, and by having the pubescence on the middle femora 
scarcely reaching to the middle: seuwtellaris and punctillatus having no longitudinal 
elevated lamina on the mesosternum, and the pubescence reaching beyond the middle of 
the middle femora (Ganglbauer, Kif: Mitteleur., iv. 1, p. 241). In these respects 
alluaudianus and chalceus approach eneus Germ., having a small but distinct elevated 
lamina, and the pubescence scarcely reaching to, and certainly not beyond, the middle of 
the middle femora. 
Paracymus evanescens (Sharp) from Ceylon and India (of which a typical specimen 
from the British Museum is before me) agrees with alluaudianus and chalceus in 
possessing a small elevated mesosternal lamina and in having the pubescence not reaching 
beyond the middle of the middle femora. But it is much smaller than either of those 
species (the specimen before me measures only 1} mm.) and quite distinct from them in 
punctuation (see below): also the underside (in this specimen at any rate) is, with the 
exception of the head, much lighter-coloured, being yellowish. 
Paracymus minor Régimbart (Ann. Soe. ent. France, Ixxii. 1903, p. 33) has a minute 
longitudinal elevation on the mesosternum, but in it the pubescence extends beyond the 
middle, to about ? the length of the middle femora: in this latter respect it differs from 
alluaudianus, chalceus, evanescens, &c., and approaches scutellaris Rosenh. &e. But 
though minor differs thus from evanescens, yet in their upper surfaces these two species 
are rather closely alike. They are the same size, and in both of them the elytral 
punctures, instead of being simple and circular, have the form of minute figures-of-8, as 
though each puncture were formed by the coalescence of two”: in this point therefore 
they differ widely from alluaudianus and chalceus. In evanescens the cephalic and 
thoracic punctures are larger and subobsolete, in minor finer and clearer cut. Paracymus 
evanescens and minor are therefore quite distinct from one another, and from alluawdianus 
or chalceus: minor is known from Madagascar and perhaps occurs also in British Kast 
Africa; I have been able to study the type of the species through the kindness of 
M. Alluaud. 
Paracymus alluaudvanus is named in honour of Monsieur Charles Alluaud. 
Loc. Seychelles: Mahé; marshes on coastal plain at Anse Royale, I. 1909, 66 
specimens. Coetivy; 1905, 2 specimens. 
* Note, this only applies to the elytral punctures: cephalic and thoracic punctures are simple.
