eye-suggesting effect not unlike the correspondingly situated black 

 spots in the larva of Cerura vinula. 



The Imago is allied to H. postica (Walk.), a native of 

 Natal and the Traosvaal, but easily distinguished by its 

 conspicuous grayish-white costal and inner - marginal 

 borders in the fore-wing, and generally much lighter and 

 brighter colouring, as well as by the bright red stem of 

 the antennae, which in j.¥. postica is pale arenaceous. 



There is, however, in the British Museum an unnamed 

 ^ of a much closer congener, from " Coomassie (H. White- 

 side)," which also has the antennae-stems red (though 

 paler than in H. phyllocampa), but in which the field of 

 the fore-wing is white, with scarcely a vestige of the dark- 

 brown clouding, while there is a rather large fuscous spot 

 in the discoidal cell near its extremity.* 



A comparison of the Larva with Boisduval's description 

 and figures t of that of iZ". milhmiseri (Fab.), a well-known 

 species of wide Palaearctic range, affords several points of 

 agreement in the two caterpillars, vid. : — (1) the bright 

 pale yellowish-green of the general colouring, (2) rufous 

 head, (3) rufous spot on each side of anterior upper edge 

 of first thoracic segment, (4) position on first abdominal 

 segment of principal dorsal process, and (5) profile outline 

 of elevated seventh, eighth, and ninth abdominal segments, 

 especially dorsal prominence of eighth segment with its 

 mammillated apex. But the differences are great, the 

 II. phyllocam'pa larva presenting no approach to the long 

 forked dorsal process occupying the first abdominal seg- 

 ment, nor any trace of the curved claw-like dorsal pro- 

 cesses which succeed it on second, third, and fourth 



* Prof. Aurivillius (Arkiv. for Zoologi, II, No. 12, p. 27, 1905) 

 notes a Notodontid larva from Camaroon, and gives an illustration 

 reproducing the sketch of it made by the discoverer, Lieut. A. 

 Schultze. The profile and back views given are so very like the 

 larva of H. phyllocampa, that I think it not improbably may prove 

 to be the larva of the closely-allied Hoplitis above mentioned as a 

 native of Coomassie. It is noticeable tliat the profile sketch of the 

 Camaroon larva shows a much higlier and larger prominence dor- 

 sally on first abdominal segment than the larva of H. phyllocampa 

 possesses, and that it represents a very erect attitude of the entire 

 fore-part anterior to the third abdominal segment — which does not 

 appear (from Mr. Millar's photographs) to be assumed by the Natal 

 larva — and a corresponding very much less recurved and indeed not 

 far from perpendicular carriage of the expanded hind segments.
