54. Mr. G. W. Kirkaldy on Aquatic Rhynchota. 
The female apparently has no facial impression. — 
Head very convex, frons with a longitudinal median carina. 
Pale: first segment sublunate; second segment short, very 
narrow, slightly convex, subeylindrical. 
N.B.—This second segment appears to be a genuine second 
tarsal segment, not a single claw. The “ Klaue” of the 
pale of various Coriae mentioned and figured by Fieber (Bull. 
Soc. Impér. Moscou, xxi. (1° partie) tab. x. fig. 9 &., 1848) 
seems to me to be only a rather stiff palal bristle. 
Long. 6:2-7°3 millim.; lat. pronot. 2°4-3 millim.; lat. 
max. hemiel. 3°5 millim.

Corixa, Geoff. 
2. Corixa eurynome, sp. 0. 
Corixe atomaric, Illiger, remote affinis; capite fere rectangulari, 
oculorum marginibus lateralibus interioribus fere perpendiculari- 
bus capitis ad basin; pronoto hemielytrisque non rastratis, 
punctatissimis; pronoto subacutangulato; tibiis unguiculisque 
intermediis subsequalibus, tarsis longioribus. 
¢. Faciei impressione fere ad verticem attingente; palis anguste 
cultratis. Strigili minutissima, subquadrata, dentium seriebus 
latis quattuor instructis. 
Q. Faciei impressione labioque ovoidem formantibus; palis an- 
guste cultratis. 
Very different from any other described Coriaa, in appear- 
ance not unlike C. atomarda, Illiger, superficially. 
Shining ; ead almost rectangular, pale testaceous, interior 
lateral margins of the eyes almost perpendicular to the base 
of the head. 
Pronotal angles rounded, subacute. 
Pronotum and hemielytra sordid testaceous, more or less 
infuscated, densely furnished with black punctuations, not 
rastrate ; no pronotal or hemielytral guttulate or vermiculate 
lineations, although the regular and dense punctuation gives 
the appearance of narrow black lines; hemielytra paler at the 
base (owing to absence of punctuation), covered with short 
pale hairs. 
Meso- and metanotum black ; mesosternum medianly black. 
Ventral aspect of abdomen and pedes (including coxe) 
flavo-testaceous ; intermediate tibie rather longer than 
unguiculi, which are much longer than the tarsi. 
6. Hacial impression reaching almost to the vertex; 
dorsal aspect of head rather longer than in female, not longi-
