[May, 



hind margin of the last ventral segment in the female of distinguendus is misleading, 

 because that part in the female of my insect has two small triangular teeth about 

 equidistant from the sides of the segment and from each other, and would, in fact, 

 be well represented by Fieber's figure of that part in Falleni if the two teeth shown 

 in the figure were a little closer to each other. In examining a number of specimens 

 one, of course, meets with slight differences of degree in these parts, but it is to be 

 obserred that the hind margin of the last ventral segment which Fieber in his figure 

 gives to distinguendus is of the same character as that of Flori and picturatus ; that 

 is to say, the central projection is the result of a notch near each side of the segment, 

 and not as in Falleni (and distinguendus as I know it), caused by the production of 

 the hind margin into small triangular teeth at two points. There is the more reason 

 to suspect some mistake in this instance as Fieber's figures, as a rule, are very 

 characteristic.

This species, of which a few specimens have been taken by Mr. E. Saunders at 

 Chobham, has considerable superficial resemblance to D. pascueJlus ; it belongs, 

 however, to the same group as pulicaris, &c., in which the crown is rather convex 

 than excavated, and it may further be distinguished from pascuellus by the costal 

 vein not being conspicuously whitish ; it is pale brownish-yellow above, and the 

 veins of the elytra being almost imperceptibly margined with fuscous have the 

 appearance of being unusually wide. The genitalia of both sexes, which I have 

 examined, are well figured by Fieber (/. c, pi. vi, fig. 39), and our insect agrees well 

 with Flor's excellent description.
