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 Poly cent ropus in the restricted sense. See my 

 "Bevision 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.

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. Kingi. One of these, from Alferce, 22nd 

 May, appears to agree in all respects ; three others from Monchique, 

 19th May, Cea, 11th June, and Villa Eeal, 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 EELOTIDM EROM JAPAN. 

 BY GEORGE LEWIS. 



In the Trans. Ent. Soc, 1874, p. 44-7, my friend, the Eev. H. S. 

 Gorham, has described a species of Helota from this country, and last 

 summer J found a second, a small mountain species, quite distinct 

 from any of the three or four now in the catalogues. I propose to 

 call it — 



Helota ceeeo-puxctata. 



Coppery-bronze, shining, head and thorax closely and somewhat coarsely punc- 

 tured, the latter having 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 striae 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 6tria? 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.
