not improbable that he mistook the Aphelia AjJolUnaris (a large broad-winged, 

 active day-fljing insect) for a female of his own species ; as I once saw, at 

 Natal, the male Dladema Misippus for a long time pursue a female Danais 

 Clirysippus, though in this case no union ensued. Aphelia is usually located 

 among the Saturtiikhc, but it presents points of affinity to the Liparidce also. 

 A. Apolllnaris is in both sexes often yellow instead of white; its wings are 

 subdiaphanous, and almost identical on both surfaces as to colour and 

 pattern. It is so active in the day-time as constantly to be mistaken for 

 some species of Ficruhc among butterflies." 



" On a supposed Femcde of Dorylus helvolus (Linn). 

 •' 'I'lie gravid female ant, of which a rough outline is here given, was 

 brought to me by Mr. C. A. Fairbridge, Senior Trustee of the South- 

 African Museum, on the 29th May, 1880, with the information 

 that it had been dug out from a nest of small red ants on 

 his premises at Sea Point, close to Cape Town. These 

 small ants were a nuisance, and he was obliged to order 

 the destruction of their nest; but, with his wonted attention 

 to all matters of zoological interest, he instructed the man 

 charged with the work to look for and secure the large female 

 or females which probably inhabited the depth of the nest, 

 and the single specimen figured was dug out. It is a very 

 remarkable insect in appearance; in colour chestnut-red, 

 paler on the abdomen, and very highly polished throughout, 

 especially in the abdominal region. There is no trace of 

 eyes (compound or ocelli) on the globose subcordate head. 

 The antennfe are 8 — 9 jointed ; the mandibles strong, curved, acute, 

 without tooth ; these two pairs of organs very like those of Dorylus 

 (male), but shorter and thinner. All the males are like those of 

 Dorylus (male), but the femora more attenuated ; the thorax shaped very 

 similarly to that of the figure (F. Smith, in Cat. Hymen. Brit. Mus.) of 

 Anomura worker, but considerably wider in proportion to the head; peduncle 

 of abdomen wider than thorax, its posterior angles outwardly acuminate ; 

 rest of abdomen greatly widened (the segments 3, 4 and 5 being the widest 

 and much flattened), and terminating in a pair of strong, horny, fuscous 

 processes ; the entire abdomen more than three times as long as the head 

 and thorax together. 



" This specimen was slightly injured about the anal extremity, to which 

 some viscid matter and grains of earth were adhering. On removing this 

 secretion T found and removed three small reddish worker ants entangled 

 in it, one of them still alive. These measure only about li line in length, 

 and were found under the lens to be eyeless, and in general structure close 

 to, if not identical with, Anomura. Through one of the horn-like abdominal
