EUROPS.—ANEUROPS. 573 
the mandibles is much smaller than usual; the hind angles are really free though 
inconspicuous. The thorax is scarcely so broad as long, not flattened, nearly straight 
at the sides, none of the angles are prominent, the hind angles are very obtuse, the 
lateral margin is inconspicuous; though crenulate, the punctuation is rather coarse ; 
there is no distinct smooth space and not a trace of a basal impression, The elytra 
are very regularly sculptured; the sete rising from their punctures are difficult to 
detect. The legs are rather slender. ‘The coxal lines are not detached. 
EL. discedens in many respects comes near Hesperobenus. 
ANEUROPS, gen. nov. 
Coxee anteriores omnino incluss, sat parvee; acetabulis externe prolongatis ; trochanteres haud parvi. Pro- 
-sterni suture discrete. 
This genus differs from Europs in the larger front cox, as well as by the head not 
being constricted between the eyes and the posterior angles. It has quite the facies 
ot khizophagus and connects Hurops with the Rhizophagine. It is distinguished from 
Lhizophagus by the transversely less elongate anterior acetabula, and by the absence 
of antennal grooves on the underside of the head. 
We figure the prothoracic parts of this interesting form (Tab. XVIII. fig. 4a). 
It is clearly connected with Europs by means of E. convergens. The number of 
joints in the feet is open to the same uncertainty as it is in many other of the 
allied forms: if the tarsi are 5-jointed, then the basal joint is so extremely short 
that it remains doubtful whether it is more than the articular portion of a joint. 
Counting it as a joint, the second and third joints are short, but rather broad; the 
fourth joint is small and forms, in fact, merely a part of the long terminal joint. 
In the male the fourth joint of the hind foot has disappeared, though there is 
perhaps a trace of it in the form of a dark mark on the basal portion of the fifth 
joint. The second and third joints are broader in the male on all the feet than 
they are in the female, and have a good deal of pubescence beneath.
