THE CANADIAN ENTOMOLOGIST. 267 



found that Aspidites was proposed by Waagen in 1895 for a genus of 

 Cephalopoda ; Aspidites, Berl. & Leon., may therefore be changed to 

 Hemiberlesia^ 



(3.) Diaspis persimilis, n. sp. — 9 scale about 1^2 mm. diam., snow 

 wiiite, slightly convex ; exuvi^ sublateral, brownish-orange, first skin 

 wholly on second, c? scale unknown. 



9 . — -Circular, orange-brown, hind end strongly striate. Five groups 

 of ventral glands, median 25 or more, nearly touching cephalolateral, 

 cephalolateral about 15, caudolateral 7 to 12. Anal orifice small, caudad 

 of caudolateral glands, but some distance from hind end. Only one pair 

 of distinct lobes, these rounded, not particularly large, very slightly 

 inclined to be crenate on edges, nearly touching at base; at outer base of 

 each lobe a spine ; then a spinelike plate, the branching tips of which 

 slightly exceed the lobe ; then a pair of minute tubercles representing the 

 second lobe, then a spine ; then a very large and stout spinelike plate, 

 branched at tip ; then three minute tubercles, then a spine ; then a spine- 

 like plate resembling the second but not quite so stout ; then a slight 

 notch, followed by a minute tubercle, then on the margin at intervals 

 twelve ordinary spinelike plates of moderate size, and a few spines. At the 

 bases of the median lobes are short dark sacs, a pair to each ; and smaller 

 sacs mark the places of the obsolete lobes on the margin. The oval and 

 elongate glands in rows marking the obsolete segments are comparatively 

 itw in number. 



Hub. — Crowded on fruit of " Chico Sapote," Laguna, Carmen I., 

 Mexico, April 24, 1896. (Townsend : Div. Ent., No. 7184.) Very near 

 to D. amygdali (lanatus); it may be recognized by the small number of 

 orifices in the caudolateral groups of glands, the form of the lobes, and 

 other minor details. 



(4.) Comstockiella sabalis,\. mexicana, v. nov. — 5 oval, orange- 

 yellow. Grouped glands as follows : Caudolaterals 14-17 (6-io in type); 

 mediolaterals 11-15 (4-7 in type); cephalolaterals 7-10 (4 in type). 

 Scale as in type. 



Hab. — On palms which arrived at San Francisco from Mexico ; 

 found by Mr. Craw, who thinks the palms came from near Maratlan, and 

 were growing wild about 75 or 100 miles inland. The genus is new to 

 the Mexican fauna. 



(5.) Lecaniutn ( Eu/ecanium) perditum, n. sp. — 9. Long. 3, lat. 

 2 to 2l{, alt. 13/^ mm., general shape low-conical or hemispherical ; very
