432 Mr. G. J. Arrow on the 
Apogonia (“ Plectris”) solida, Walk.= A. ludificans, Brenske. This was 
described by Brenske as a variety of A. comosa, Karsch, but I be- 
lieve it to be specifically distinct. It is invar iably larger, with the 
head and pronotum less closely punctured and the front tibia less 
produced at the end. 
A. comosa, Karsch. I consider it doubtful whether this really occurs on 
the mainland of India as maintained by Brenske. 
A, lateralis, sp. 0. 
A. lurida, Karsch. 
A, nana, Walk. The type is unique and in bad condition. 
A. equabilis, Karsch. 
A, gracilis, sp. 1. 
A. coriacea, Wat. 
A. nietneri, Kolbe. 
A. fulvosetosa, sp. 0. 
Schizonycha ruficollis, F.= (“ Rhizetrogus”’) equalis, Walk, and S. singha- 
lensis, Brenske. This was described by Fabricius from Southern 
India, and Brenske gives no sufficient reason for distinguishing the 
Ceylonese specimens. After a careful comparison of many examples 
from both Ceylon and the mainland (including the types of Walker 
and Fabricius) and a male specimen determined by Brenske himself 
as S. singhalensis I have come to the conclusion that they are 
identical. The genitalia of the males are alike. 
Engertia maculosa, Brenske, A peculiar insect, decorated with patches 
of scales, of which apparently only a single female is yet known. 
Confirmation is needed of its Ceylon habitat. 
Lepidiota (‘‘ Melolontha”) ferruginosa, Walk. 
Leucopholis pinguis, Burm.=“ Melolontha” rubiginosa, Walk. 
I. horni, Brenske. Unknown to me. 
Stephanopholis singhalensis, Brenske. 
S. rubicundus, sp. 0. 
S. cribricollis, sp. 0. 
S. melolonthoides, Brenske. Brenske saw specimens of this labelled 
“ Columbien” and “ Manila,” both of themimprobable localities. It 
seems possible that the former was a mistake for Columbo; but I do 
not know the species. 
Holotrichia serrata, F.= H. ceylonensis, Moser. The minute differences 
pointed out by Moser do not seem to indicate more than a slight 
local race, of which probably many might be distinguished in this 
wide-ranging species. 
FH. insularis, Brenske. 
H. reynaudi, Blanch.=“ Melolontha” pingiis, Walk., and H. remorata, 
Brenske. M. Lesne has kindly established this synonymy for me 
by examination of Blanchard’s type in the Paris Museum. In his 
table of the Ceylon species (Stett. ent. Zeit. Ixi. 1900, p. 858), and 
in Mem. Soc. Ent. Belg. 11. 1894, pp. 19 & 66, Brenske has applied 
Blanchard’s name to the following species. 
i. disparilis, sp. n.= Holotrichia reynaudi, Brenske. 
H. scabrifrons, Brenske. This species, described from a single male in 
1892, Brenske has entirely omitted in his table of 1900. Mr.G. Lewis 
found asingle female, nowin the British Museum, at Bogawantalawa. 
FH, (“ Rhizotrogus”) inducta, Walk. 
H. (“ Rhizotrogus”) hirtipectus, Walk.= H. convertfrons, Moser. 
IT, (‘* Melolontha”’) setosa, Walk. 
H., rufoflava, Brenske.
