282 THE CANADIAN ENTOMOLOGIST, 



Asp idiot US ( Targionia) Marlatti, sp. nov. 



9 scale 2 mm. in diameter, flat to slightly convex, dark reddish- 

 brown, resembling walnut, on margin to a lighter shade at centre ; exuviae 

 lateral, large, black, often covered with brownish secretion; ventral pel- 

 licle thin, light reddish-brown, not easily separated from scale, and leaves 

 no mark on host plant when detached. 



9 oval, white, with irregular spots of yellow ; ultimate segment 

 yellovv, with the mirgin dark brown and strongly chitinous. Boiled in 

 caustic potash, the female becomes transparent, with the exception of the 

 lobes, which remain yellovv. There are three pairs of lobes (Fig 36), which 

 are short, broad, and quite widely separated, with the sides parallel ; first 

 pair either broadly rounded or truncate, and notched at distal end ; 

 second and third lobes similar, broader than mesal lobes, notched on 



Fig. 36. 



margin, with that part lateral of the notch generally the larger. There is 

 one small spine at the base of each of the mesal lobes, one larger one at 

 the base of the lateral margin of each of the second and third lobes 

 respectively, and another one on margin as distant from the third spine 

 as the combined width of one mesal and one second lobe. Chitinous 

 processes are of medium size, one pair to each incision ; the ones lateral 

 of mesal lobes are the largest. Plates are short and truncate, and appar- 

 ently easily shed, as they do not appear in the boiled specimens ; in the 

 untreated specimens there are from one to two plates to each incision. 

 There are no groups of circumgenital glands. The dorsal glands are 

 large and fairly numerous. On each side and posterior of the anus there 

 are a few tubular glands. 



This interesting species was collected by Mr. J. B. Norton, who 

 found it upon the base of the stems of grasses, Andropogon furcatus and 

 A. scoparius, on Blue Mont, Manhattan, Kansas, and is named in honor 

 of Mr. C. L. Marlatt, in recognition of his many valuable contributions to 

 the knowledge of the CoccidK.
