consisting of more elongated joints, than may be seen in typical specimens 
of obtusa. Without studying a larger series of this form, I cannot decide 
whether those characters are sufficiently constant to be specific, and I pro- 
pose in the meantime to designate it as var. vikescens ; n. The dimensions of 
the typical specimen (female from Amara, Mesopotamia) are, as follows : — Length 
of body 39 mm.; of pronotum 7 ; of elytra 28 ; of hind femur 16, 5.*

No. 29. 
There is no doubt though the types of cincticollis, Walk., are lost, that this 
species is identical with morbosum, Serv., both insects having been described 
from Sinai ; I have seen two females from the same locality : Sinai, J. Couayt, 
1909 ; desert Arabique, Mahamadieh, canal de Suez (Paris Museum). In 
British Museum there is one female of this species, which is labelled “ Spain” 
which is doubtless wrong and due to some mistake in labelling. I am not quite 
sure, whether the species belongs to Tkisoecetrus, where it is included by some 
authors, but the question cannot be decided, until male specimens are 
studied.

Shortly after I described carbonaria I had 
the opportimityof stud /ing extensive series 
of the same insect from different loca- 
hties in Transcaucasia, Persia and Kurdis- 
tan, as well as of maMng some field obser- 
vations on living insects, which enables me 
to state, that it is quite a distinct species 
from italicus, 1j. The examination of a 
single male in British Museum from Syria 
(Aleppo) enables me to identify carbonaria 
mth coelesyriensis. The species is rather 
variable in the development of lateral keels 
of pronotum and, as its coloration also 
varies from pitch-black to reddish-grey or 
clay-yellow, it might be mistaken for 
italicus. It differs, however, from the lat- 
ter species by shorter and broader hind 
femora, and, more distinctly, by the shape 
of end of male cerci, which in italicus is 
armed with two small teeth under the 
apical lobe, while in coelosyriensis there is 
only one tooth ; these differences are clearly shown in figures (see fig. 2). 
This species is distributed from Syria to Turkestan (Ferghana) and from S. E. 
Transcaucasia to Central Persia (Teheran, in Caucasian Museum ; Pusht-i-Kuh,

* Specimens of Tropidopola from Algeria, whence I have studied only three 
examples, are mor j alike obtusa, than cylindrica in the shape of fastigium, b:it they 
differ by the frontal carinse being gradually coiivergent, as in clylindrica. I propose to 
regard the Algerian Tropidopola as a geographical race of the desert o6<mso., un(mr the
