with a pale median line bifurcate anteriorly, and two darker indefinite narrow 
submedian longitudinal fasciae. Pronotum pale with fore and hind part of 
disc castaneous ; the hind castaneous part being twice as broad as the fore one ; 
both are connected by a longitudinal median castaneous fascia, including a 
pale median line ; a round pale point near fore margin and another before 
hind margin ; lateral lobes pale. All legs pale ; hind knees with castaneous 
semilunar patches. Elytra not strongly infumate ; wings hyahne, feebly 
infumate apically.

Two males (type and paratype) taken at Ktubu, Arabia, by G. W. Bury 
in 1902. 
I have the great pleasure in naming this interesting species after Dr. L. Chopard, 
who has done so much for increasing our knowledge of Orthoptera, and especially, 
of Gryllidce. 
The species is somewhat similar to B. megacephalus, Lef., but it differs from it 
in many important characters, as follows ; — Head in B. chopardi is but a little 
broader, than pronotum ; trapezoidal space between eyes higher than broad, while 
it is transverse in megacephalus. Pronotum in new species is lelatively longer, less 
narrowed posteriorly ; lateral lobes distinctly longer than high and but feebly 
widened downwards. Tympanal field of elytra is distinctly transveise in 
megacephalus, while it is as broad as long in chopardi ; apical field is relatively 
'bnger. Apical spurs of fore tibiae in chopardi are thick and much shorter than 
first joint of tarsus, while in megacephalus they are thinner and longer ; apex 
of first joint of fore tarsi is in new species not truncate, as in megacephalus, but 
obtusely prominent. The larger apical spurs of hind tibiae (i.e., ail, except 
inner upper ones) are subequal to one-third of metatarsus, while in megacephalus 
they aje almost as long as a half of metatarsus. From another related species, 
B. membranaceus, the new species differs partly by the same characters, as 
from megacephalus, but is most easily separated by the form of the head, which 
in membranaceus is not wider, than pronotum ; pronotum in the latter species 
is not narrowed posteriorly ; median ocellum in chopardi is placed on a very 
small tubercle, while in membranaceus this tubercle is very distinct ; apical field 
of elytra in membranaceus is distinctly longer than one-third of elytra.

d . Size rather small for the genus, just a little larger than that of A amarensis 
Chopard. 
Head distinctly broader, than pronotum, though not as broad comparatively, 
as in campestris L., in profilb very little prominent before eyes. Face in its 
lower part slightly impressed, or rather inclined, forming a very obtuse, but 
distinct, angle with clypeus ; the latter is also subangularly prominent in its 
middle, if seen in profile ; two scarcely perceptible impressions run obliquely 
from base of antennae towards the middle ocellus, not reaching the latter. Pro- 
notum not much broader than long, equally broad throughout ; fore margin 
s'ightly excavate ;hind margin straight ; a feeble median impressed line not
