Ascaphium apical Cj .sp. n. 



Angiistato-ovatum, nigrum, iiitidum ; autounis articulis apicalibus 



rufis ; tiliis nigris vel rufo-pict-is. 

 L. 3k miU, 



Elliptical, black, sometimes faintly metallic ; moutli-orf!:ans, 

 six basal and the apical joints of the antennte red ; the head 

 clearly, not densely punctulate ; the thorax similarly punc- 

 tured ; the elytral sculpture resembles that of A. tibiule; the 

 legs are black or pitchy red. 



This species is smaller than A. tibials; the apical joint of 

 the antenna is pale or red and the anterior tibia3 are ahke in 

 both sexes. 



IJab. Found in the same localities as the last species. 

 Rare. 



Scaphitim optabile^ sp. n. 



Oblon<jo-ovatum, nigrum, nitidura ; supra punctulutum ; antcnnis 



pcdibusquc concoloribus ; metusterno iuciso. 

 L. 4 mill. 



Oblong-oval, black, shining; head robust, somewhat closely 

 punctulate; the thorax more distinctly punctured and the punc- 

 tures less close, the stria behind the neck very fine, leaving a 

 narrow smooth margin ; the elytra with the sutural stria punc- 

 tate, entire, and continuing along the base, surface punctured 

 more finely than the thorax, but without linear arrangement ; 

 the propygidium has an elevated margin at the sides, and 

 the base of the pygidium is laterally somewhat similar ; both 

 segments are finely punctulate; the claws are pale. The meso- 

 sternum is formed like that of a species of Scaphidiu7n, trans- 

 verse, margined anteriorly, and acutely produced in front; and 

 the metasternum is truncate anteriorly, with a median longi- 

 tudinal canaliculation, and behind, the edge is conspicuously 

 incised in the middle and rounded off on either side of the 

 incision. 



This curious species, being unique in my collection, is 

 assigned to Scaphium because of the incision in the meta- 

 sternum, but provisionally only, as in Scaphiwn the mcso- 

 sternum is robust and triangular and in this insect it is formed 

 more like that of ScajJtidium.
