Gryllidce. 
60. . Beachytrypes chopaedi, sp. n. 
cJ . Of the size and habitus intermediate between membranaceus, Drury, and 
megacephalus, Lef. 
Head slightly broader than pronotum. Face flattened, vertical, in shape 
of a regular circle (its vertical diameter being equal to horizontal one). Fasti- 
gium of vertex with a not deep impression in the form of a half-moon. Ocelli 
as usual for the genus size ; the middle ocellus placed a little lower than 
the line connecting lateral ocelli ; the latter placed on the outer side of vertical 
keels which are distinctly convergent downwards and not extending beyond 
the base of antennae ; middle facial space between these keels trapezoidal, 
distinctly higher than broad, with a wide slightly raised coarsely hneato-rugose 
transverse band ; in the middle of which there is a small tubercle with the 
median ocellum on it ; below this band face is rugose, except a smooth shining 
oval space just beneath ocellum ; lower part of face, between bases of antennae, 
is slightly convex r below and a little outwardly from bases of antennae, 
there are short vertical keels, slightly raised and obtuse. Clypeus with a dis- 
tinct transverse keel. Occiput strongly convex, raised above pronotum,- very 
sparsely and minutely punctured. Pronotum distinctly constricted in its 
hind part, but less so than in megacephalus ; its length exceeds its basal width 
by a little ; its apical width is subequal to one and a half of the length. Disc 
rugose, with a short smooth median line in the fore half. Fore margin slightly 
concave ; hind margin straight. Lateral lobes a little longer than liigh, scarcely 
broadened dowmwards ; fore margin and fore angle broadly rounded ; lower 
margin straight, slightly ascending backwards ; hind angle about 100°, rounded ; 
hind margin vertical. Elytra about four and half times as long as pronotum 
Tympanal field sUghtly longer than broad. Harpa with three long and 1-2 short 
oblique veins. Speculum oblique, elongate ; its extemo-anterior margin straight ; 
fore angle nearly straight, slightly rounded. Apical field occupies less than one- 
third of the whole length of elytra. Lateral field with 5 branches of radial vein 
and 8 obhque veins, with feeble transverse venules. Wings fully developed, 
extending about one-fourth their length beyond the apex of elytra. Fore tibia 
with a large oblique tympanum on the outer side, and with but a small one 
inwardly ; apical tibial spurs short and obtuse, the two inner ones equal to one- 
third part of the first tarsal joint ; the outer spur about one-half of the inner. 
Fore tarsi about twice shorter, than tibiae ; first joint as second and third 
together; its apex seen from beneath oblique, obtusely produced ; second joint, 
equal to one-third of the first ; third joint twice as long as second ; claws thin, 
almost straight, with apex bent, acute. Middle tibiae armed with four thick 
and short apical spurs, the two inner and lower outer one being subequal in 
length to each other, while upper outer is shorter. Hind tibiae armed inwardly 
and outwardly with 3-4 irregular spines of different size and shape and with 
six apical spurs ; upper inner spur is the longest, reaching about the middle 
of metatarsus, and incurved ; two lower spars short and rather thin, the inner 
of them being a little shorter than the outer ; three remaining spurs are sub- 
equal in length to each other, about one-third of metatarsus, thick, straight. 
Metatarsus equal to one-half of tibia, armed with three short irregular spinules 
outwardly and four inwardly, and with two apical spurs, the outer spur being 
quite short, very thick and obtuse, wdiile the inner reaches about the middle of 
the third joint of tarsus, thick, slightly recurved, with obtuse apex. Supraanal 
plate thick, with middle part impressed. Cerci slender long, with long per- 
pendicular hairs. Subgenital plate acutely navicular. 
General coloration brownish-pale. Face pale, with the suture between it 
and clypeus blackish-brown ; trapezoidal space upwai-ds from the middle ocellum 
and its lateral margins, as well as upper margin of antennae impressions, 
castaneons ; vertex light castaneous, the colour gradually fading in occiput
