SUMMARY OF CURRENT RESEARCHES RELATING TO 
Alpine Orthoptera from Central Asia. — B. P. Uvarov {Journ. 
Bombay Nat. Hist. Soc ., 1921, 28, 71-5). Description of three new 
genera and species, Orinhippus tibetanus and Dicranophyma hingstoni 
belonging to the sub-family Locustidae, and Hyphinomos fasciata 
belonging to the sub-family Tettigoniidae. The last named, found in 
western Tibet, is remarkable for occurring at the extraordinary high 
altitude of 15,000 to 16,000 ft. B. L. B. 
Myiasis in India and Persia. — J. A. Sinton ( Ind . Journ. Med. 
Res., 1921, 9, 132-62, 4 pis., 8 figs.). Besides clinical notes on a 
number of cases, descriptions are given of the larva, pupa and adult 
stages of the flies Pycnosoma dux , Lucilia serricata , Sarcophaga ruficornis , 
and Wohlfahrtia sp. B. L. B. 
“ Penis ” of the Bed-bug (Cimex lectularius). — S. R. Christophers 
and F. W. Cragg {Ind. Journ. Med. Res., 1922, 9, 445-63, 3 pis.). 
The female has two sexual apertures, a copulatory orifice and an orifice 
for oviposition. The so-called “penis” of the male is claw-like, 
■carried laterally and bent to the left, in correlation to the position of 
the copulatory orifice of the female, and the position taken up by the 
pair during the act of copulation. The structure is not the penis at all, 
but merely a grooved director along which the true intromittent organ 
glides during the act of copulation. The phallosome had been overlooked 
so far. It lies at the root of the so-called penis and has all the chief 
characters of the phallosome in the order generally, though greatly 
reduced in size and complexity. The sexually modified segments of the 
female with their appendages are described and given their homologous 
denotation, in the light of comparative study and development.

Conjugation and Reduction of Chromosomes in Scolopendra. — 
P. Bouin ( Comptes Rendus Acad. Sci ., 1922, 174, 968-70). In 
Scolopendra cingulata there is no interkinesis between the last gonial 
division and the spermatocytic prophase. The twenty-four chromosomes 
of the spermatogonia are transformed directly into the spermatocytes 
with twenty-four leptotene filaments, which conjugate in pairs, longi- 
tudinally, yielding twelve pachytene loops. After a stage of nuclear 
rest, twelve double filaments reappear, and these condense into twelve 
pairs of chromosomes in the form of rodlets. These divide longi- 
tudinally in the second maturation kinesis. The maturation thus occurs 
on the hetero-homeotypic plan, and the numerical reduction of the 
chromosomes is effected by the longitudinal conjugation of the sperma- 
togonial chromosomes. J. A. T. 
Myriopods from Mesopotamia and Persia. — H. W. Brolemann 
{Journ. Bombctg Nat. Hist. Soc., 1921, 28, 165-9, 2 pis.). A new 
Lithobiid, Lithobius buxtoni, distinguished from its nearest relative, 
L. melanops Newpt., by its rugose tergites and by the spinal armature 
•of the legs, is described from Persia. The sexual characters of the 
female of Strongylosoma persicum , previously unknown, are described 
.and illustrated, and certain blanks in Lignau’s diagnosis of Polyxenus 
ponticus are filled up. B. L. B.
