100 THE ENTOMOLOGIST. 



mouth as far back as July 8th, 1835. The following species of 

 Homoptera occur in the nests of this species : — Rijx'vsia tomlinii, 

 Newst.; and of Goleoptera, Tyclias glahratus, Rye, and Trichonyx 

 maerkellii, Aube. 



From the foregoing lists it will be seen that the following 

 number of species inhabit ants' nests : — Goleoptera, 54 ; Lepi- 

 doptera, 1 ; Neuroptera, 1 ; Hemiptera, 1 ; Homoptera, 12 ; 

 Diptera, 1 ; Thysanura, 1 ; Acari, 3 ; Onisci, 1 ; total, 75 species. 



THREE NEW SPECIES OF COCCID^. 



By T. D. a. Cockerell, 

 Entomologist of the New Mexico (U.S.A.) Agricultural Experiment Station. 



Ceeoplastes iheringi, sp. nov. 



Waxy scale greenish white, very irregular, nodose, without 

 distinct plates. Length 4, breadth 4, height 3 mm. Female 

 with the wax removed, 3 mm. long, 2 broad, dark olive-brown. 

 Posterior cleft nearly 1 mm. long. Caudal spine distinct, but 

 very short and broad. Dorsal and lateral projections ill- 

 developed. When boiled in soda, the female produces a strong 

 madder-red colour. Legs yellowish ; femur stout ; tarsus and 

 tibia of equal length, or tibia a little longer. Claw moderate, 

 curved. Digitules of claw very remarkable, brown, darker than 

 leg or claw, long, extending considerably beyond tip of claw, 

 stout, sub-bulbous at base, with very large round knobs. Tarsal 

 digitules slender, with large brown knobs, but these not so large 

 as those of the claw-digitules. Antennae pale brownish, cylin- 

 drical, not or hardly tapering, distinctly 8-jointed ; 3 and 4 about 

 equal and longest ; then 8 and 2 about equal ; 5, 6, and 7 short 

 and subequal, about as long as broad, 6 the shortest. Formula 

 of antennpe (34) (821) (57) 6. Last joint suddenly narrowed 

 before its middle, and bearing several hairs. 



Hab. Eio Grande do Sul, Brazil ; on Baccharis lolatensis, 

 Griset. Collected by Dr. H. von Ihering. Baccharis is a genus 

 of Compositae of the tribe Asteroideae. 



Dr. von Ihering sent the specimens in alcohol; but at the 

 same time sent dry specimens of the same species, also on 

 Baccharis (species not stated), from Sao Paulo, Brazil. These 

 latter specimens show two lines of white secretion on each side ; 

 they also show the spine or "tail" larger, though still very 

 stout. The two localities for the species are about 600 miles 

 apart. 



Allied to G. ccriferiis and C. fairmairei (which Maskell con* 

 siders a synonym of ceriferus), but distinguished readily by its 

 comparatively small size, its 8-jointed antennae, and the details 

 of the feet.
