the deeply notched labrum and the strong porrected mandibles 

 are very striking. The labrum appears to me of extraordinary 

 construction ; the mentum is large and of semicircular shape, 

 deeply emarginated, which renders the lobes heavy, rounded 

 outside, and pointed at the tip. In the bottom of this emar- 

 gination stands a pointed, spinelike tooth, as long as the lobes. 

 This tooth is deeply excavated or grooved and is clearly seen 

 to be to its full length soldered together with the basal part 

 of the ligula. Probably the entire mentum is in this manner 

 connected with the adjoining part of the ligula ; but in the 

 other parts it is not so clearly observable as in the tooth, and 



I have not dissected the labrum. The ligula itself is of a 

 leathery consistence, of the shape of an elongated inverted 

 triangle with an elevated back, the anterior margin is straight 

 and somewhat prolonged beyond what would be the sides of 

 the triangle. The paraglossse are of membranaceous texture, 

 very broad, adhering to the sides of the ligula to its full 

 length, taking then a slender, cylindric form and reaching 

 considerably beyond it, being at the same time slightly bent 

 inwards.
