Funicle joints 2 and 3 each shorter than I, 

 and 3 sliorter than i\ each about as broad 

 as is joint i at tip. Club distinctly 3-jointed, 

 a Httle broader than funicle joint 3; joints 

 I and 2 of club subequal in length and each 

 as long as funicle joint 3. Joint 3 of club 

 about as long as 2, somewhat narrower at 

 base than 2, pointed at tip. In other 

 respects resembles Coccophagus, except 

 that the hind tibiae are considerably flat- 

 tened and have a row of short stiff bristles 

 above. JMiddle tibial spur long and slender, 

 nearly as long as first tarsal joint. 



Aneristus ceroplastae, n. sp. — Female. 

 Length, .8 mm. ; expanse, 1.6 mm. ; greatest 

 width of forewings, .27 mm. Mesonotum 

 finely and closely shagreened, with sparse, 

 rather long dark pile ; eyes hairy ; color 

 black, slightly shining, all coxae and femora 

 black; front and middle tibiae and all tarsi 

 pallid, hind tibiae black. Wings with a 

 very large discal infuscated patch, covering 

 nearly half the wing area.

 T. D. A. Cockerell from Ceroplastes on 

 Euphorbia hypericijolia from Jamaica.

B\' T. D. A. COCKERELL. 



The writer having lately prepared descrip- 

 tions of various new Coccidae, which will 

 appear in sundry bulletins, reports, proceed- 

 ings of local societies, and so forth, it is 

 deemed expedient to bring together some 

 account of them here. This is done for the 

 convenience of students, who sometimes 

 complain of the difficulty of keeping track of 

 scattered descriptions; and also to secure 

 earlier publication, as some of the fuller 

 accounts may be (indeed, have already been) 

 much delayed. While the full details are 

 not now given, there is sufficient descriptive 

 matter, it is hoped, for the ready identifica- 

 tion of the species. The species collected in 

 Japan by Mr. Takahashi were obtained for 

 the Department of Agriculture and trans- 

 mitted to me by Mr. L. O. Howard. Those 

 collected by Prof. C. H. T. Townsend are 

 also the property of the Department. Those 

 obtained by Mr. Craw were collected at San 

 Francisco in the course of his quarantine 

 work. Full particulars concerning all of 

 the Takahashi, Townsend and Craw species 

 will be given in a forthcoming Bulletin of 

 the Department of Agriculture. The West 

 Indian forms will probably receive full pub- 

 lication in Trinidad. 



Dactylopius olivaceus, n. sp. — f 'ong. 34, 

 lat. 2.4, alt. i4 mm. (in alcohol). Dark olive- 

 brown, with mealy powder. Legs shorter 

 than their distance from one another, very 

 stout, coxa extremely large, digitules all fili- 

 form. Antennae brown, slender, 8-jointed, 

 S very long. Formula 8 (123) (67) 54. Hairs 

 of anal ring very small. Posterior tubercles 

 obsolete. On Yucca, Ciudad Perfirio Diaz, 

 Mexico (Townsend). Rather like Z). ^/a//- 

 fu.s, Maskell. 



Eriococcus dubius, n. sp. — 5 with sac a 

 little over 3 mm. long, sac loosely felted, 

 white, with a slightly yellowish tinge. Dried 

 9 very dark reddish-purple. Antennae 

 7-jointed, formula 34 (12) 756. Legs mod- 

 erately slender, digitules ordinary. Posterior 

 tubercles small but cvlindrical. On some 

 shrub, Valles, Mexico (Townsend). Very 

 near to E. coccitieus, Ckll., but apparently 

 distinct. 



Phenacoccus pergandei, n. sp. — $ with 

 sac S mm. long, 3 broad. Sac white, firm, 

 partly overlapping the wrinkled orange- 

 brown ?. Antennae g-jointed, formula 32 

 (14569) (78). Tarsus less than half as long
