THE AUCHBNORRHYNCHOUS HOMOPTERA. 93 



only partly covering the pygidium ; legs rather elongate, the tarsi 

 moderately broad, their first joint as long as the following two together. 



There is no genus amongst the Clythridae into which the 

 present species may be satisfactorily placed, principally on 

 account of the strongly rounded and widened sides of the thorax 

 and the partly uncovered pygidium, which agrees iiearly with 

 Diapromorpha, but the thorax in that genus is of totally different 

 shape. 



MiCROPYGA TRANSVALENSE, Sp. n. 



Under side black, pubescent ; upper side fulvous : thorax im- 

 puuctate ; elytra strongly punctured in closely approached rows ; a 

 semicircular spot on the shoulders and a transverse band below the 

 middle black ; base of the tibias fulvous. Length, 7 mill. 



Hah. Transvaal. 



Head impunctate at the vertex, the latter convex, intraocular space 

 finely rugosely punctured, with a single small fovea ; another one is 

 placed at the base of the antennae ; clypeus very feebly emarginate 

 anteriorly, the anterior edge black ; eyes slightly notched ; sides of 

 the head truucately produced below the eyes ; antennae comparatively 

 elongate, black, the fourth and following joints strongly transversely 

 serrate ; thorax twice as broad as long, of equal width, the sides and 

 the posterior angles strongly rounded, the disc rather convex, entirely 

 impunctate, fulvous ; scutellum rather broad, obsoletely carinate, 

 blackish ; elytra not wider at the base than the thorax, the basal 

 margin ridge-shaped, the punctuation arranged in closely approached 

 irregular rows ; an angular semicrescent spot or band placed at the 

 shoulders, not extending to the suture, and another slightly oblique 

 baud below the middle extending nearly to either margin, and slightly 

 widened near the suture, black ; under side black, closely pubescent, 

 the base of the tibiffi fulvous ; presternum not visible between the coxae. 



I have three specimens before me, which I received from Mr. 

 Fruhstorfer. 



ON THE MORPHOLOGY AND CLASSIFICATION OF THE 

 AUCHENORRHYNCHOUS HOMOPTERA. 



By Dr. H. J. Hansen.

4. FulgoridcE. — This family naturally falls into two principal 

 divisions, viz. Fulgorinse and Delphacinae, the last being marked 

 out by the long-known powerful movable sjmr at the apex of the 

 posterior tibiae, whilst this spur is lacking in all Fulgorinae ; in 

 the next place (see above) the sensory organs on the second pedun- 

 cular segment of the antennte are furnished with bristles in the 

 Delphacinse, but in the Fulgorinae with lamellar lobes, " blades," 

 which sometimes are feebly but generally very well developed.
