borders of lakes, rivers and streams; I note this, because 
I unfortunately do not now remember the exact locality, 
where the specimen was taken, but I strongly suppose 
that it has been found together with some of the said 
coleoptera in a locality abounding with water, which in 
the districts, where I collected, was more or less mixed 
with salt and saltpeter. 
I describe the new genus as follows: 
Mendocinia n. gen. 
Somewhat resembling Aépophilus. Ground colour rufous 
brownish. Elongatety oval, all over densely clothed with 
a pale, short pubescens. Upper side 
of body slightly, under side strongly 
convex. Sides of pronotum distinctly 
marginate. Eyes very small, hairy. 
Hemelytra short, squamiform, sub- 
truncate behind, outer apical angle 
bluntly rounded (not acutely pro- 
duced as in Aépophilus). Legs and 
antenne pubescent. Antenne 4- 
articulate; joints subequal in thick- 
ness, unequal in length; Ist and 3rd 
joints short (3rd a little longer than Fig. 1. 
Ist), 2nd and 4th joints equal in Mendocinia hygrobia 
É n. gen. et n. sp. 
lene each one twice as long 4S © afore tasus; b hind tarsus’ 
Ist; 4th joint slightly fusiform. Ros- a male senitalia: ¢ rostrum. 
trum long, quadri-articulate; Istjoint  reriy enlarged. 
the thickest; Ist and 2nd joints equal in length, each one 
about as long as 2nd joint of antenn&; 3rd rostral joint 
not nuch shorter than 2nd joint; 4th joint the shortest 
and thinnest. Each pair of legs with same length of 
femur and tibia; tibia slightly flattened towards apex; 
tarsi 3-jointed; Ist and 2nd tarsal joints short, of equal 
length; 3rd joint about as long as Ist and 2nd together; 
claws thin, rather long. Evaporatory organs ending in a
