only by the anal parts of the <$ , which are distinct from those of the 
other described forms. The supplementary inferior appendages, and 
the very long and strong penis, are especially remarkable, in which 
points of structure there is some analogy with the genus Plectrocnemia , 
but the insect is a true Polycentropus in the restricted sense. See my 
“Revision and Synopsis,” p. 397. 
Desiccation alters the forms of the anal parts very considerably, 
and it is only occasionally that the structure can be clearly demon- 
strated in dry examples. 
Rig. 1 represents the anal parts of the <$ , from above ; fig. 2, the 
same, from side. 
Mr. King’s captures induced me to make an examination of a 
series of specimens of Polycentropus, taken by Mr. Eaton in Portugal, 
in 1880. I found that these consist, probably, entirely of undescribed 
forms, and amongst them are four examples that, in all probability, are 
specifically identical with P. Kinyi. One of these, from Alferce, 22nd 
May, appears to agree in all respects ; three others from Monchique, 
19th May, Cea, 11th June, and Villa Real, 23rd June, respectively, are 
much larger (Expanse, , 18 — 20 mm.), and more strongly marked, 
but the structure appears to agree. Scotland and Portugal are widely- 
separated localities, but, considering the great similarity of the species, 
and the neglect from which they suffer, there is all possibility that this 
particular species occurs in the intervening districts.

A NEW SPECIES OF HEL0TID2E FROM JAPAN. 
BY GEORGE LEWIS. 
In the Trans. Ent. Soc., 1874, p. 447, my friend, the Rev. II. S. 
Gorham, has described a species of Helota from this country, and last 
summer I found a second, a small mountain species, quite distinct 
from any of the three or four now r in the catalogues. I propose to 
call it — 
Helota cereo-pl]s t ctata. 
Coppery-bronze, shining, head and thorax closely and somewhat coarsely punc- 
tured, the latter haring a smoother irregular portion before the scutellum, extending 
half-way up from the base. The thorax is parallel, hinder angles acute, with the 
centre portion of the base less sharp than in gemmata. The elytra are evenly and 
regularly punctate-striate, the striae, ten in number, with interstices very slightly 
convex. The usual wax-like spot before the middle of the elytra is round, and 
occupies the interstices of the 4th, 5th, and 6th strife from the suture, the punctures 
of the 5th being visible down its centre. The second spot is situated before the 
apex, where the 4th and 5th strife terminate and join, and it is more oblong than 
the 1st. Antenna? pitchy-bronze. All the thighs are red for the basal half of their 
length ; and the abdomen is pitchy-red. Length, 4 lines.
