SOME NEW AND LITTLE- KNOWN COCCID.E COLLECTED 

 BY PROF. C. H. T. TOWNSEND IN MEXICO. 



BY T. D. A. COCKERELL, N. M. AGR. EXP. STA. 



The Coccidi« Iierein described were collected by Prof. Townsend in 

 1896, and kindly transmitted to me for study by Dr. L. O. Howard. The 

 collection made by Prof. Townsend will be fully enumerated in a paper 

 to be published by him elsewhere, so the present contribution is confined 

 to descriptions of the new species and descriptive notes on one hitherto 

 imperfectly known. I have also ir.cluded the description of a new variety 

 of Comstockiella from Mexico, not found by Townsend. 



(i.) Aspidiotus reiii/ormis, n. sp. — ^ scale circular, diam. 2 mm., 

 Hat, pale reddish-brown ; exuviae concolorous or slightly darker, covered, 

 but both skins very distinctly visible, large, laterad of the middle. First 

 skin when rubbed shining copper)\ 



9 . — Reniform, yellow with a brown margin ; the posterior portion 

 large, pale yellow, projecting with the outline of a cone, unusually pro- 

 duced and narrow, the sides meeting at less than a right angle. Pygidium 

 (so-called) minutely striate; anal orifice oval or subtriangular, a long 

 distance from hind end. Four very small low broad inconspicuous lobes, 

 the plates between them scarcely visible ; these lobes are twice as broad 

 as long, the second about or nearly as broad as the first. Immediately 

 cephalad of the second lobe comes a pair of small diverging spinelike 

 plates; then after an interval somewhat greater (sometimes less) than the 

 distance from the hind end to the plates just mentioned, comes a depres- 

 sion in which is a larger, but still small, pair of diverging spinelike plates; 

 beyond this the margin is distinctly but very minutely serrate, with three 

 small pointed prominences at rather long intervals, and a small rounded 

 notch about half way between the first of these and the largest plates. 



There are long tubular glands opening at the bases of the lobes, and 

 also at the place of the obsolete third lobe ; these are three on each side, 

 with others, shorter and smaller, between them. Caudolateral grouped 

 glands a long distance cephalad of the anal orifice. Four groups of 

 ventral glands, caudolaterals 4 to 7, cephalolaterals 8. The antennae are 

 represented by small tubercles, each emitting a bristle. On each side of 

 the mouth, some distance from it, is a small reniform orifice, its convexity 

 directed laterad. 



Hab. — Numerous on under sides of entire, lanceolate leaves, about 

 60 mm. long. Tehuantepec City, Mexico, May 26th (Townsend; Div,
