130 COLEOPTERA OF NORTH AMERICA. 



slightly above the epistoma ; the labial palpi are normal in form. 

 The pro-sternum is quite distinct before the coxa?, but not visible 

 between them. The middle coxae are not covered by the front 

 coxae, which are conical and prominent, and the hind coxal plates 

 are suddenly dilated internally ; the tibiae are cylindrical, with 

 long slender spurs ; the tarsi are rather short, the second joint 

 slightly, the third broadly lobed beneath, the fourth small, the 

 fifth a little longer than the third, with the claws broadly toothed 

 or appendiculate. Fifth ventral segment emarginate. 



Tribe II.— EUBRIIjVI. 



Broadly ovate convex, finely punctured and pubescent insects 

 found on plants near water. The head is deflexed as in the other 

 tribes, but the antenna? are more approximate, contracting the 

 front which forms a narrow beak ; I do not observe any frontal 

 suture ; the maxillary palpi are slender, and much elongated ; 

 the labial palpi are short ; the prosternum is very well developed 

 in front of the coxa?, and is quite visible between them, and pointed 

 behind, though not prolonged ; the mesosternum is nearly square, 

 somewhat concave. The anterior coxa? are transverse, and not 

 very prominent ; the middle coxa? are distant ; the plates of the 

 hind coxa? are very narrow, slightly dilated internally. Spurs of 

 the tibia? obsolete, tarsi filiform, with the fourth joint slightly' 

 smaller than the third, fifth as long as the three preceding united. 

 The fifth ventral segment is rounded at tip ; claws dilated at 

 the base. 



There is a small fissure at the front margin of the anterior 

 coxa?, which produces the appearance of a trochantin, but under a 

 very high lens, it is seen that this fissure does not extend across 

 the coxa, so as to separate the outer portion. 



Our species are found only in the Atlantic States, and belong 

 to the genus Ectopria Lee. It differs from the European Eubria 

 by the mesosternum being oblique and slightly concave, instead 

 of flat and emarginate in front as in that genus. Eurea Lee, 

 founded upon Eubria nervosa Mels., must be suppressed into 

 Ectopria. The typical specimen was in very bad condition and 

 the small lobes which appeared to exist under the tarsi are not 

 visible in well-preserved individuals.
