Melolenthine Beetles of Ceylon. 431 
Periserica (“ Omaloplia”) interrupta, Walk. 
P. (“ Sericesthis”) subsignata, Walk. The type is a unique and very 
defective female. 
P. nigripennis, sp. 0. 
Selaserica nitida, Cand. 
S. scutellaris, sp. D. 
S. sericea, sp. n. 
S. pusilla, sp. n. 
Serica variolosa, Motsch, = S. maculifera, Brenske. Although Mot- 
schulsky’s description of the legs is rather incomprehensible, there 
seems to me to be no reasonable doubt that his insect, which Brenske 
found himself unable to identify, is the latter’s S. maculifera. It is 
curious that Brenske has charged Motschulsky with omitting to 
give the dimensions—a fault of which he is not guilty, but which 
Brenske himself, in the same paper, has perpetrated more than once 
(see Autoserica cinerea and Neoserica splendifica, p. 431). 
S. rubescens, sp. n. 
S. fusa, Brenske. 
8. lurida, Breuske. This afd the two following species are unknown to 
me. 
S. nana, Brenske. 
S. distincticornis, Brenske. - 
S, (“ Sertcesthis”) confirmata, Walk. 
S. maculicauda, sp. n. 
Autoserica (“ Sericesthis”) mollis, Walk.= A. singhalensis, Brenske. 
Brenske has referred to the considerable variations in size exhibited 
by this insect. ‘Thesmaller form, to which his type belongs, is gene- 
rally distinguishable by sharper hind angles to the pronotum and 
less sharp and rather abbreviated supramarginal carinz to the elytra. 
It can hardly be regarded as specifically distinct. 
A, (“ Sericesthis”) rotundata, Walk.=S. immunita, Brenske. 
A, straba, Brenske. I do not know this species or the two which here 
follow. 
A. implicata, Brenske. 
A. fistulosa, Brenske. 
A. cinnabarina, Brenske. 
A. calearata, Brenske. 
A. chalybea, Brenske. 
A, weligamana, Brenske. 
A, dubia, sp. 1. 
A. cinerea, Brenske. Unknown to me. 
A. pubescens, sp. n. 
Neoserica bombycina, Karsch. 
N. splendifica, Brenske. Unknown to me. 
Apogonia rauca, F.=(“ Anomala”) punctatissina, Walk. TI believe 
Apogonia soluta, liberata, and vatacta, of Kolbe (the last mistakenly 
referred to as ‘ incerta” and ‘“‘inserta”’ by Brenske, Stett. ent. Zeit. 
1900, p. 349), to be forms of A. rauca, F., as well as Brenske’s 
var. unistriata. 
A, proliva, sp. 0. 
A, ferruginea, F.= A. uniformis, Bl., and A. anfracta, Karsch. The 
types of A. ferruginea and rauca are in the British Museum. 
A, cava, Karsch. This is a doubtful species. The fragmentary descrip- 
tion applies entirely to A. ferruginea, of which the type may bea 
rather large specimen.
