Type (from Miami, Fla., female and male). No. 11860, 

 U. S. National Museum. This neat little tingitid is most 

 nearly allied to G. C. Champion's Acysta 3 - intcrrupta, recorded 

 from Panama. The latter species, however, differs in having 

 three pronotal carinse and the membranous lateral margins 

 interrupted only in the middle; besides, the nervures in that 

 species closing the discoidal areas are well defined. 



The U. S. National Museum possesses several specimens 

 from Florida which have been found infesting Per sea caro- 

 linensis and Per sea gratissima (alligator pear or avocado), 

 and other specimens coming from New Orleans, La. (La. 

 Exp. Sta. a. c. 457) are labeled " living on camphor trees 

 (C amphora officinalis}." 



Eggs were examined on foliage of avocado twigs. They 

 were deposited on the underside of the leaves, standing up- 

 right in irregular rows ; they are of the usual tingitid egg 

 shape, of a dull yellow color with a white rim to the lid. Each 

 egg is more or less thickly covered by a dark, sticky secretion 

 from the insect. 



Nymphs, probably in the fifth stage of their development. Body 

 oblong-oval, dark yellowish, except towards base of abdomen where 

 the color becomes lighter with some scattered small reddish spots. On 

 each abdominal segment, on each side near the lateral margins arises 

 directly from the surface a peculiar prolongation in the shape of a 

 cylindrical process ; the two on the fourth and last segments are most 

 prominent. There are also some thicker and larger processes in the 

 middle of the first, fourth, fifth, and seventh segments dorsally; some 

 tubercles at each side of the wing pads ; two large processes placed near 

 together on the metanotum, and less prominent ones at each side of 

 thorax. The head carries three strong spines in front and two large 

 strongly curved horn-like processes at base, which are conspicuously 

 roughened. The processes at lateral margins of abdomen are yellowish- 

 white towards the end, a little thickened and rounded at tip, with a 

 few pores and short bristles; the others are dark brownish. Head 

 brown. The thorax shows some dark patches; the lateral margins 

 yellowish- white, nearly transparent; the wing pads, which extend to 

 the fifth abdominal segment, are entirely translucent except for a 

 blackish streak at base. Dorsal part of abdomen more or less speckled 

 with reddish and brown.
