REPORT ON ZOOLOGY, MDCCOXLII : 
East Indies, must be named Ceratitis capitata ; the new species 
C. hispanica, Br., is from Andalusia, and should be distinguished from 
the older species by the shorter length and deeper setting of the lobed 
bristles of the forehead, which form the chief characteristic of the genus, 
as well as by the black colour of the lobes, which in the other are 
whitish. These distinctions appear tome doubtful; Wiedemann gives 
the colour of the lobes expressly as black, which my observations confirm, 
and I can find no other diiference between C. capitata, from the Isle of 
France, and a specimen from Sicily, than that these bristles in the 
latter are somewhat shorter, and not so remarkably long as the author 
has given them ; it might be held as an individual difference. 
Bachmann (Ent. Zeit. p. 263) has made some remarks upon Trypeta 
slgnata. Mg., the larva of which lives in the substance of sweet and 
bitter cherries ; and, according to C. Wagner’s observation, is found in 
the fruit of the Lonicera xylosteum. 
Von Siebold (Germ. Zeitschr. iv. p. 389, t. 1, f. 1-3) has remarked 
black protuberances on the abdomen of Bacillus Rossii, which proved, 
on more minute examination, to be the forked breathing processes of the 
orange-yellow larva of a fly, 4"' long, sticking in the body ; he did not 
succeed in rearing these parasitical larvae. 
PupiPARA. — The reporter (Arch. 1842, i. p. 274) has described a new 
species from Van Diemen’s Land, Ornithomyia nigricornis. 
HEMIPTEEA. 
A PECULIAR apparatus, for connecting the anterior and posterior wings 
in the Hemiptera, has been discovered and described by Ashton (Trans- 
act. Ent. Soc. iii. p. 95). In Notonecta glauca are found, on the under 
side of the anterior wings, at the posterior margin, two small horny 
projections, which together form a small tubular channel. A minute pro- 
jection of the rib-like thickened anterior margin of the posterior wings is 
bent upwards and backward, and grasped in this channel. In Centrotus 
cornutus, a small portion of the anterior margin of the posterior wings, 
is turned upwards, and from this springs a small horny process, directed 
backwards, which fits into a recess of the posterior margin of the anterior 
wings, the edge of which, at that point, is bent down and reflected for- 
wards, forming a small channel for the reception of the above process. 
The small process of the posterior wings is finely dentated. The former 
kind of fastening, which is the firmer, appears peculiar to the Heterop- 
tera, the latter to the Homoptera ; in the former, the position of the 
process is at the union of the horny and membranous portion of the 
hemelytra, in the latter at the point of the last nervure of the anterior 
wings.
