PSYCHE. 



[January 1901 



The $ scale is smooth elongate oval 44 to 

 5 mm. long ; 2 to 3 broad, and 2 high. Color 

 variable, reddish brown, yellowish brown to 

 a tinge of greenish brown, rounded dorsally 

 without ridges forming an H though this 

 character is found in the immature individu- 

 als. Antennae 8-jointed measuring in y. 

 joint 1(56), 2(60), 3(84), 4(52) 6(36) 7(28) 8(56), 

 joint I has one hair, 2, two ; 3, three ; 4 three ; 

 5 two; 6 one; 7 two and 8 eight. Front 

 leg: coxa 120 long; femur with trochanter 

 240; tibia 168; tarsus 88. Tarsal digitule 56 



long. The outer margin of the skin after 

 treatment with potash is much darker than 

 the rest, and the entire surface tessellated, 

 and thickly covered with oval gland orifices. 



Saissetia filicum. 



Lecanium filician Boisd. 1868. 



$ Scale yellowish red brown to red brown, 

 practically hemispherical, though some ex- 

 amples found at the ends of the small twigs 

 and leaves of the food plants are some- 

 what elongate. The adult ? scale and young 

 having one longitudinal and two transverse 

 ridges forming a raised H marginally dis- 

 tinctly keeled. The longitudinal ridge has 

 4 minute raised round tubercles, and the 

 entire scale more or less minutely pitted, 

 surface somewhat shiny. Size 3 mm. in 

 diameter and 2 mm. high. 



Antennae 8-jointed in |x long 1(52) 2(48) 

 3(56) 4(44) s(2o) 6(24) 7(28) 8(40). Front leg : 

 coxa 120; femur with trochanter 200 ; tibia 

 152 ; tarsus 88. The skin marginally dark 

 ocherous thickly covered with large oval 



gland orifices. The center and large portion 

 of the skin colorless with the gland pits very 

 indistinct. 



It seems to the writer that the names 

 of the above two species are misplaced. 

 S.filicutn should be called .S. hcmisphae- 

 rica and the latter 6'. filicum, owing to 

 the fact of S. filicum as it now stands is 

 a hemispherical shaped species, while S, 

 hemisphaerica is an elongate oval one. 

 Indeed it seems as though S. filicum was 

 the one originally described as L. Itemi- 

 sphaei-icum. The marginal hairs of the 

 four above species are all very similar 

 with expanded ends which are more or 

 less split interspersed with ordinary 

 sharp spines without expanded ends or 

 split. The lateral incisions of all are 

 also of the same shape similar to a half 

 oval. 



Saissetia hemisphaerica was received 

 from Prof. Cockerell, collected by him 

 Aug., 1901, at La Galla, San Diego 

 county, Calif., on pepper tree {Schinus 

 molle), on Cycas ci?-cinalis, Trinidad 

 (West Indies) from Dr. L. Reh, and on 

 fern in greenhouses in Mass. Those 

 of S. filicum were from ferns in green- 

 houses, Lawrence, Mass. collected by 

 myself.
