labour, viz. from July 18th, 1825, when Burchell first landed 

 at Rio de Janeiro, until Feb. 10, 1830, when be left Pard'. 



Westwood^s list of Burchell's "Acrcea &c." consists of 

 twenty-two numbers, of which only three — A. 8, A. 9, and 

 A. 10 — refer to the AcrEeinee as now understood. The 

 numbers and data were written under his direction by a 

 clerk, while ^'Acrcea sp.," together with notes descriptive o£ 

 individual varieties, were inserted by Westwood himself. He 

 also wrote a supplementary and more complete catalogue of 

 the data of A. 8, A. 9, and A. 10 on a separate slip of paper, 

 but a single date, correctly recorded by tiie clerk, is omitted 

 from the slip — a remarkable error, considering that Westwood 

 was the writer. E. G. Joseph.

Acti7iote thalia, Linn.

The inner marginal spots of the fore wing are both distinct 

 in this specimen, the upper, as usual, being considerably 

 smaller than the lower. A fuller account of this character is 

 given under 1444. 



The wings of this specimen are unusually broad and 

 rounded, — more so than in normal males and females. They 

 are also far more translucent than those of the typical male 

 of thalia, thus approaching the characteristic appearance of 

 the female. In size the specimen is intermediate between 

 the small male and large female of this species. An exami- 

 nation of the genitalia and of the fore legs nevertheless shows 

 clearly that the specimen is a male, although an unusual 

 form of this sex. The rounded character of the hind wings is 

 also evident in the rectangulated band of their under surface. 

 (For a description of this band see under 1444.) It would be 

 very interesting to endeavour to ascertain by breeding whether 

 this is a well-marked form of male or one that is transitional 

 into the normal A. thalia of S.E. Brazil. Two other similar 

 specimens (1449 and 1453) were captured by Burchell in 

 Minas Geraes between 14. 10. 25 and 10. 11. 25.

 but four additional plants beyond 10108 were collected on Feb. 7th and 

 one on Feb. 8th.
