Ceratovacuiia brasiliensis, Ilcntpd: a Correction. 



The writer described a supposed new species of Aphidie under the 

 above n:iine in the Ann. & Majr. Xat. Hist, vol viii., Xov. 1001. 

 Since the publicition appeared he has received the ' Monograph of 

 British Aphidc-s ' by Mr. G. h. Bucton, and in the Appendix of vol. iv. 

 found a description of Ceratophi^ I tttn'up (Boisd.). According to this 

 description the two species are identical, and C. hra.s'ifi nsis, Ilempel, 

 is a synonym of C-rutophis latanUe (Boisd.). This species was first 

 described by Boisduval in 1867 as Coccus latanice. Later Signoret 

 described it as Boisduvalia hita)ii<^, and after that Lichtenstein, 

 recognizing its true affinity, gave it the name of Ceratophls Intanuf. 



It is clear that Zehntner had not seen this description when he 

 created the genus Ceratovacuna for his lanhjera, as such a step was 

 \innecessary in view of the fact that both species have the same 

 distinguishing features and agree in many points. Cerntovicuna, 

 then, is to be regarded as a synonym of Geralophis, ret lining lalnnias 

 (Boisd.) as type of the genus, and regarding lani(/era. Zehntner, as a 

 second species of the same genus, which may be characterized as 

 follows : — 



Genus Cer.vtophis, Lichtenstein. 



Svn. Ceratovacuna, Zehntner. 



Wingless form with antenu^ie of four joints, joint 3 being longest. 

 Cornicles represented by small perforated tubercles. Cauda not 

 developed. Two large horns project forward on the ventral surface 

 of the head between the antenna}. Larvae and adults secrete a white 

 wax, which may entirely cover them or may be in the form of a 

 marginal fringe. "Winged forms with antennte of five joints, of 

 which joint 3 is the longest. AVings folded horizontally on the back. 

 Frontal horns and cauda not developed. Fore wings with four 

 oblique veins. Cubital vein with one branch. The first and second 

 oblique veins united at the base. Hind wings with two oblique 

 veins. All forms viviparous. 



Type Ceratophis latani<x (Boisd.). 



Characters of the species : —

Svn. Coccus latfnii'fe, lioisd. 



Boisduvalia latanice, Sign. 



Dark brown or nearly black, the dorsum of the apterous form 

 slightly covered with a very thin layer of white wax, a transverse 

 white band separating the thorax from the abdomen, and with a 

 conspicuous marginal fringe of white wax.
