to each 2ncl, 3rd, and 4th lobe, and another similar pair beyond, also close to the 

 margin. One similar solitary gland between the bases of the dorsal lobes. A simple 

 plate between 1st and 2nd lobes, two between 2nd and 3rd, and two between 3rd 

 and 4th, with about six along the margin as far as the commencement of the first 

 distinct segment. A stout spine adjacent to the base of each lobe, and a fifth on the 

 margin, about midway between the 4th lobe and the first distinct segment. 



I found this species in the conservatories of Senr. Loureiro, in 

 Oporto, on the stem and leaves of Znmia villosa. I have classed it in 

 the genus Diaspis, for although I have not found the male, I think it 

 cannot be an Asjndiofus, as in all the species of this genus that 1 have 

 seen, the 1st larval skin lies in the centre of the 2nd. It seems tome 

 that the relative position of the exuvise to one another, is a very 

 constant character in the Diaspina, and is consequently of some 

 imj^ortance.

 transversely depressed at its posterior half, the anterior portion rather swollen, the 

 disc strongly and rather closely punctured, clothed with some yellow pubescence, 

 only visible in certain lights ; scutellura piceous ; elytra distinctly raised at the 

 base, this portion limited by a transverse depression, the punctures very distinct and

Sab. : Brazil, St. Catharina, Rio Capivary. 



Two specimens which I refer to the present genus were kindly 

 given to me by Herr Fruhstorfer, who obtained them at the above 

 locality.
