It has the size .iiul fif(Mieral form of G. trlvxltata and the 

 pattern of the liead, iironotiim, and seutclliim is similar, l)ut 

 with the yeUow lateral patclics of the pronotum hroader, 

 leaving two rather irregular shining hlack stripes, whieh are 

 finely and not closely puuetured. The scutellum is mode- 

 rately long, but not acute at the apex. The elytra are covered 

 with whitish tomentura, except for a narrow shining mar- 

 ginal line and two narrow diseoidal stripes, the first running 

 from the base parallel to the sutural margin and the other 

 from the humeral angle, meeting the first just before the 

 apex. The pygidium is thinly pubescent, not shining, and 

 has a rounded patch of yellow tomentum on each side. The 

 body is covered with similar tomentum beneath, except for 

 a quite smooth median line. The mesosternal process is 

 sjlender and curved.

This is the smallest so far known in the group of species 

 to whieh it belongs, and is much more variable in colouring 

 than the rest, which seem to adhere with gi-eat constancy to 

 a particular shade ot" vivid green, softened by pinkish rcHec- 

 tions in a certain light. The same colour is found in the 

 ])resent species, but a cobalt-ljlue changing to a rich jjurple 

 is equally frequent, and our series includes one specimen of a 

 fiery red. The borders of the pronotum are usually of a paler 

 colour than the disc. 



//. pygnuea most resembles H. uliernata, Kl., but, in 

 addition to its smaller size, is much more hairy, the head 

 and the metastcrnvim (except a small area in the middle of 

 the latter, whieh is (juite smooth) being clothed with long 

 tawny hairs, that upon the head standing erect. The 

 pygidium, on the other hand, is smooth and shining, and
