SPOLIA ZEYLANICA. 
II.— Lachnus Greeni, sp. n. 
Body somewhat elongated, produced anteriorly and posteriorly^ 
dark, entirely covered (including legs and antennae) with numerous 
fine bristles carried on small granules. 
Vertex convex, with a median longitudinal impression. Eyes 
dark grenat or obscure red-brown, with posterior appendix obtuse 
and somewhat obsolete. No frontal tubercles. Antennae (fig. 4) 
about equal to one-third of the body; first and second joints stout, of 
equal length ; third the longest, fourth nearly equal to half third, 
fifth longer than fourth, (sixth) hardly longer than or equal to 
fourth, (seventh) equal to half second, thus, 1*, 1*, 3-75, 1*7, 2*, (1*8), 
(0*5), — or 1*, 1% 3*5, 1'5, 2*, (1/7), (0*5) ; fifth joint with a large 
subapical fovea and another before this ; sixth with a large fovea 
and several smaller at tip ; seventh indistinctly annulated. 
Rostrum reaching posterior coxae, somewhat prominent at base 
under the vertex, dark, last joint black. Legs of moderate size 
densely pubescent, specially the feet; tibiae and tarsi with dark 
tips. 
Segmentation of abdomen obsolete ; the segments furnished on 
each side with a small obtuse tubercle (more conspicuous in the 
young specimens). Cornicles cone-shaped, half the body length, 
truncated at tip, with a prominent apical margin, pubescent 
Tail not separated from body, obtuse rounded, furnished with 
minute tubercles between which are other thicker; apical part 
with the bristles somewhat longer and denser, directed backwards. 
Length of the body : 2*20-2*50 mm. 
Of this new species I have seen only the viviparous apterous 
form, which Mr. Green collected in the nests of an ant, Gremato - 
gaster Doihrni , For., on the roots of an undetermined Gryptomeria , 
in Peradeniya. 
III.— -OREGMA BAMBUSiB, Buckt. 
This form was first described some years ago by J. B. Buckton, 
in the Indian Museum Notes. But his description is unusually 
incomplete, and the drawings reproduced in his paper are not at all 
exact: thus, the tarsi are represented with the two joints of equal 
length (a fact which would be most interesting amongst Aphides !) 
when in reality the first is much shorter than the second ! 
Owing to these bad descriptions and figures probably the genus 
was not recognized by the well-known entomologist of the Proef- 
station in West Java, Dr. Zehntner, when he described his new 
genus Gercitovacuna (Archief voor de Java-Suikerindustrie, V.), 
for the reception of G. lanigera , Zehntn., a predaceous Aphid on 
Saccharum , of which he has given an accurate description with
