adult 9 characters agree perfectly, as figured and described by Signo- 

 ret, but the description of the appearance of the adult 9 's in life, in 

 situ on the food plant, agrees perfectly, the 9 being covered with a 

 cottony secretion and bearing pendant from the oval end a single long 

 cottony filament. 



Found on leaves and twigs of a wild shrub or small tree called 

 ." escobillo, " in woods, Arroyo San Isidro (near Frontera), Tobasco, 

 May 27, 1897 (Townsend). Div. Ent., No. 7659. The cottony fila- 

 ments hanging pendant from the 9 's reached a length of something like 

 three inches. 



This rediscovery of Capulinia sallei is of great interest, not only 

 per se, but further as throwing much light on the affinities of several 

 more recently described allied genera. The study of the present ma- 

 terial has demonstrated the close relationship of Capulinia with Sphcsro- 

 coccus Mask. (1891), and Xylococcus Loew (1882). Both Capulinia 

 and Xylococcus fall in the Jdiococcince of Maskell, and in fact could 

 both be included in the genus Sphcerococcus as characterized by that 

 author. However, the genus Sphcerococcus may be maintained for 

 forms of the S. casuarince Mask, and acacice Mask, type, while S. infla- 

 tipes Mask, needs the erection of a separate genus for its reception. S. 

 bambusce Mask, has already been referred to Antonina. Other species 

 described since by Maskell as Sphcerococcus will need similar revision. 

 Xylococcus filiferus Lw. of Austria, resembles Capulinia sallei in the 

 presence of the long pendant cottony filament of 9 , but apparently 

 differs in the presence of an anal cone and other minor characters. The 

 genus Sphcerococcus, as above restricted, will include such forms as have 

 the feet entirely absent in the adult 9 , and the antennas either absent 

 or rudimentary. Capulinia will include forms in which not only the 

 antennae, but also the feet, at least the posterior pair, are represented in 

 more or less rudimentary form, and are not entirely absent. While both 

 the feet and antennas are said by Loew to be wanting in Xylococcus, 

 the latter genus will remain distinct from Sphcerococcus by its chitinous 

 anal cone or tubercle. [C. H. T. T.] 



The description of the following Brazilian species is included here 

 while on this genus : 



Capulinia jaboticabae Von Jhering.* 



Adult 9 • Round-oval in outline, ^ 5 ' to I mm. in length. Differs from C. sallei 

 as follows : Antennae more developed but still rudimentary, about twice as long as 



* We had named this species after Dr. Von Jhering, but in the meanwhile he has 

 (Revista Agricola, June 1898, p. 188) proposed to call it Capulinia jaboticabce. Dr«
