rostrum 0-070 1-77. 



Cornicles mere warts. 



Body much slimmer than that of the female. Head 

 and thorax disproportionately developed, whilst the 

 abdomen is of small dimensions. Uniform colour 

 shining brown, with the exception of the prothorax 

 or neck-ring, which is of a reddish pitchy tint. 

 Thoracic lobes long and large. Antennge, about half 

 the length of the body, brown. Legs shining orange- 

 brown, with black femoral, tibial, and tarsal points. 

 The abdomen and legs are densely clothed with yellow 

 hair. Wings long and narrow; membrane rather 

 fuscous, except as regards the stigmatic cell, which is 

 clear and hyaline. Stigmata ochreous, cubitus brown 

 and stout, the other veins dark brown. The first 

 furcal nervure joins the cubital nervure almost at its 

 extremity, and these veins do not quite touch the 

 cubitus. All the veins of the upper wing shade off 

 into broad brown cloudy stains, which extend through- 

 out their entire lengths. All the cells are prettily 

 clouded at their basal margins, but this variegation 

 differs from that seen in D. Groaticus. The lower wings 

 are not clouded. 



A gentle pressure on the abdomen causes the pro- 

 trusion of a very large hooked penis. The curious 

 anatomy of this organ will be noticed in the section 

 devoted to the descri]3tion of the reproductive appa- 

 ratus of Aphides.
