31. Cistelomorpha congrua (Cistela), op. cit. 11, 286. 
Entirely yellow (antennae beyond 4th joint wanting) with the 
last ventral segment reddish. Elytral intervals subequal, convex, 
“rather sparsely punctate, 4th and 5th striae shortest, not united at 
apex, 3rd and 6th united beyond them, 7th stria a little short of 
uniting with 2nd, 8th still shorter, 9th (marginal) stria almost 
uniting with Ist. 
Closely resembles C. calida All., from Madura, but the 
thorax and elytral interstices are both less densely punc- 
tate, and the antennae (so far as present), tibiae and tarsi 
are not black, and the last ventral segment is reddish 
instead of black. A form occurs with a black humeral 
spot on the elytra and a black discal spot at about 2 of 
their length, thus resembling C. calida var. nigromaculata 
All. (= trabealis Fairm.), but it may be distinguished by 
its pale legs and hypopygium as well as by the less dense 
puncturation of the thorax and elytral intervals. 
Fam. LAGRITDAE. 
32. Sora marginata, op. cit. 11, 260 (Oedemeridae). 
It is probable that many of the Oriental species of 
Casnonidea and Nemostira will have to be included under 
Sora. The more salient features of the genus are the 
elongate slender form, striate elytra, of which the alternate 
intervals have a few widely spaced setigerous punctures, 
the large eyes, moderately approximate above, but more 
widely separated beneath the head; the slender antennae, 
of which the second joint is elongate, more than half as 
long as the third, and the last jot in both sexes greatly 
elongate, as long as the three preceding together. 
The type of S. marginata remains unique in the British 
Museum. It is flavous, apparently immature, with the 
tips of the antennae and femora faintly infuscate, and a 
broad fuscous streak running from the humerus nearly to 
the apex of the elytra; but this coloration is probably very 
inconstant. 
N.B.—Thaccona dimaelana, op. cit. ii, 260 (Oede- 
meridae), has already been stated by Mr. Champion to 
be an Idgia (=I. cardoni Bourg.), Ann. and Mag. Nat. 
Hist. (9) ii, 1919, p. 360.
