422 Mr. G. W. Kirkaldy on the 
Not unlike N. ‘rrorata, Uhl, in hemielytral pattern, very 
pubescent, hemielytra dull black; clavus yellowish-brown or 
castaneous, mottled or faintly striped with blackish-brown, corium 
black obscurely irrorated with castaneous. Notocephalon a little 
wider at the base than in other forms. 
(8) specimens from L. Kharak, Persia (Paris Mus.), 
and Transcaspia (my coll.), which are not unlike some 
forms of N. insulata in hemielytral pattern. 
Clavus and basal half of corium luteotestaceous ; exocorium, 
apical half of corium ferruginous, spotted and blotched with 
black, 
Var. 4, canariensis, nov. 
Notocephalon a trifle narrower than in the other forms. Hemi- 
elytra purple-black, obscurely irrorated with dark rich castaneous, 
margins of hemielytral areas narrowly the same colour ; anterior 
half of exocorium rich castaneous blotched with black, posterior 
half black. Membrane black. Pedes rufotestaceous, suffused 
with rich green, 
Resembling somewhat a very dark, elongate N. irrorata. 
By far the most ornate Notonectid I have seen. 
Var. 5, maculata, Fabr. 
Hemielytra orange-red or orange-yellow irrorated with brownish- 
red and blackish-brown, varying greatly in shade. Alar basal 
nervures orange-yellow, rest brown. 
I have discussed this var. under var. marmorea. 
A specimen from Barbary (Paris Mus.) is almost 
chocolate, while the hemielytra of one from Algiers 
(Vienna Mus.) are scarcely maculate. 
In Fabricius’s original description, the scutellum is said 
to be “album ” which Herrich-Schiiffer deems a misprint 
for “‘atrum;’’ there are, however, in the Paris Museum 
African examples (presently to be described) with luteous 
scutellum, and in any case it is a matter of no importance 
having regard to the variability of this feature in so many 
species. Through the kindness of Prof. Bouvier and 
Prof. Joanny Martin, I have been able to examine the 
type in the Bosc collection (Paris Musewm) in which the 
scutellum is black. Under the name “ var. wmbrina”’
