DESCRIPTIONS OF ORTHOPTERA FROM S. W. ASIA. 
723 
The specimens studied are from the following localities : Kut and Amara in 
Mesopotamia ; Bushire in S. W. Persia ; Aleppo, Syria (in British Museum 
and in Bombay N. H. Society). 
6. Microthespis divutrievi, Wern. 
One male in British Museum from Bushire, S. W. Persia. The species has 
been described (Ann. Mus. Zool. Petersb., xiii, 1908, p. 120) from Djibouti and 
Harrar on the Somali Coast. 
7. Iris persa, sp. n. 
S . Agrees in all essential characters with /. oratoria, L., but differs well from 
it in the shape of head, pronotum and elytra. 
Larger than 7. oratoria and more robust. Head transverse, a little less than 
twice as broad as pronotal dilatation ; facial cl 3 rpeus about one and half times 
as broad as high, with upper keel not sharp, slightly curved, developed in the 
middle only and disappearing towards the eyes, with short vertical median 
Carina, extending from upper margin to the middle of clypeus, where there are 
two raised points ; other four raised points are at the angles of clypeus. Oc- 
ciput distinctly convex. Pronotum rather thick ; prozona slightly narrowed 
anteriorly, with parabolic apex, with feeble median longitudinal furrow ; meta- 
zona about twice as long as prozona, gradually narrowed posteriorly in its 
fore half, while in the hind half its sides are parallel ; margins of pronotum 
expanded. Elytra extending but a httle beyond the apex of abdomen, about 
three times as long as they arc in the broadest part wide ; preradial area widened 
in its basal third and rather suddenly narrowed towards the apex ; the vena- 
tion agrees with this in 7. oratoria. Wings distinctly shorter than elytra, with 
apex parabolic ; hind margin almost straight. The armure of fore legs much 
the same as in 7. oratoria, but the coxae arc more strongly spined and granu- 
lated. Supraanal plate rounded ; cerci rounded, rather thick. Subgenital plate 
with hind margin rather broad, slightly convex. 
Greenish-pale; fore tibiae with inner surface reddish ; fore metatarsus black 
beneath. Coloration of wings as in 7. oratoria.

Four male specimens in the British Museum from Bushire, S. W. Persia 
taken in September 1890, by W. D. Cumming. 
The most striking differences from 7. oratoria are : the form of clypeus, 
which in oratoria is more than twice as broad as high, with well developed upper 
Carina ; the form of pronotum and especially the relative length of prozona and 
metazona ; the length and form of elytra. Co-typic specimens are of brick-red- 
dish general coloration, but I am not sure that this coloration is natural and not 
the consequence of immersion in spirit. 
8. Iris splendida, sp. n. 
2 . About the size of 7. oratoria, L., but more robust. Antennre thin, seta- 
ceous. Frontal clypeus about twice as broad, as high, flat, with two small
