they become bright red, with a broad dark stripe lengthwise on the back, which is 

 interrupted by fine white transverse streaks. At this stage the scales are nearly 

 3.5 mm. high, 4 mm. broad, and 4.8 mm. long, consequently very globular. With 

 the development of the eggs they become tubercular, thin-shelled, uneven, furrowed 

 and tumid, and the variegated colour merges into a shining brown-red. The young 

 larvae are dark yellow, and of a characteristic stumpy form. The male imago, found 

 in April and May, has the body and head dingy red-brown, legs light yellow, an- 

 tennae dark brown, wings between the margin and nerve red-brown. 



This may be a distinct species, not hitherto separated from L.pyri, ior although 

 generally not much importance is due to the variegation of the ? scales, which is 

 more or less observable in all the reputed species of this group of them, yet the 

 transverse white streaks appear to be special to the form now mentioned, and may 

 prove to be a specific character. I find such scales here on plum and apple trees, 

 and also singly on a pear tree, in May ; but I have yet to learn how to distinguish 

 the male from L. pyri. 



Lecanium ribis, A. Fitch. 



Under the head of Lecanium persicce, Dr. Goethe introduces a form which he 

 finds on gooseberry and currant bushes, which he is inclined to believe is identical 

 with that species. Assuming that it is the same as that I find here common on 

 gooseberry and currant bushes, I would rather believe it to be L. ribis, which is 

 much more like L. rugosum, Sign., than persicce, yet I think distinct. Like Dr. 

 Goethe I have never found a male of this currant feeder.

DESCEIPTION OF TWO NEW SPECIES OF TERACOLUS. 



BY ARTHUR G. BUTLER, F.L.S., F.Z.S., &c. 



The following interesting species have recently been presented to 

 the Museum Collection by Mr. J. M. E. Johnston : — 



Teracolus Joiinstoni, sp. n. 

 ? . Allied to T. Eris, but larger and in some respects more like the female of 

 T. subfasciatiis ; the apical border of the primaries being bright copper-brown instead 

 of black, bounded internally by three diffused bright ochreous and one white spot in 

 a curved oblique series, these again bounded internally by an oblique black band 

 from costa to third median branch, the latter continued by two spots (the upper 

 crescentic, the lower sub-quadrate) upon the median interspaces ; the internal 

 blackish streak narrow, and at its outer extremity curving up in the form of two 

 unequal spots almost to the first median branch ; secondaries of a dead white tint, 

 slightly pink in certain lights, and with faintly yellowish border ; the base slightly 

 dusky ; a transverse tapering bifid brownish dash from costal margin to second 

 median branch : below the differences are even more marked, the apical area and 

 costal margin of primaries being of a bright gravel-ochre colour ; six brownish spots
