OBSERVATION'S ON THE GENUS CATOCULA. 11 



vary in number from 32 to 40, about half of which combine l)oforo 

 reaching the micropybxr area. The colour is uniform bronze-green, 

 which is sufficient to distinguish it from all others hitherto examined. 

 The lateral ribs are very numerous. Only one larva emerged, but died 

 from the exertion. I only mention the fact, as it goes to prove that 

 the eggs were fertile. The imago is practically a small European edition 

 of the following species. 



C. concnmbeyis. — The ova are very conical above ; the micropyle 

 rather large. The vertical ribs number about forty, the lateral ribs 

 very fine. The colour is bronze-green, without any markings. In 

 this respect it resembles the preceding. It measures about -OlSin. 



Two larvje emerged during April, and as I had plenty of eggs, I 

 unfortunately omitted to take any notes of their early stages, as I 

 counted on having others later on. However, no more emerged, and 

 one larva had meanwhile reached its third instar, the other having 

 died. As far as I remember, in the first two instars it did not differ 

 much from its near relatives, C. niij)ta and C. electa. In the third 

 instar I also did not take notes soon enough, as on opening the glass 

 to take the larva out, I found it moulting for the third time. The third 

 instar was, however, very striking, as it did not resemble any of the 

 others. The ground colour was yellowish-grey, with a red-brown 

 patch on each segment, which would have formed a broad dorsal 

 band, but for the fact that the segmental divisions were of the ground 

 colour. The head was red-broAvn, with the usual streaks on the lobes. 

 In the fourth instar the larva measured about l^in. The head red-brown, 

 with a black streak on each lobe and black markings on the face. The 

 ground colour is velvety reddish-brown, the segmental divisions, 

 especially of the abdominal segments, which are vei-y broad, forming 

 paler rings, the larva being apparently ringed alternately witli red- 

 brown and grey. The hump is very small indeed for the fourth 

 instar ; it is red, with a minute black ring round it. The tubercles 

 are also bright red, both anterior and posterior trapezoidals being 

 very prominent and wart-like ; the latter are somewhat larger than 

 the former. The post- and subspiraculars are also large, the 

 remainder being quite small and scarcely noticeable. The usual ridge 

 is formed by the posterior trapezoidals of the eighth segment, the 

 streaks also being present. The lateral fringe is well developed, and 

 crimson in colour. Beneath the larva is much suflt'used with crimson, the 

 spots being large. This larva died whilst moulting for the last time. 



The imago is about as large as C. niipta: the fore-wings, head, 

 and thorax smoky-grey ; the collar brown. The fore-wings have two 

 fine irregular black lines crossing the Avings, one on each side of the 

 orbicular. The orbicular itself is lighter than the rest of the wing, 

 and just below it is a white spot. The hind- wings are pale crimson 

 with both bands very regular. The marginal band is somewhat broader 

 at the outer angle than at the inner angle, and tapers gradually ; the 

 inner band is very broad, it having evidently spread towards the base. 

 The hind marginal fringe is white, the inner marginal fringe pale 

 brown. On the under side this species has several significant markings. 

 On the fore-wings the outer black band does not strike the hind 

 margin about the centre as in ( '. elocata and ( '. niijita, but at the 

 anal angle, thus leaving a band of grey along the whole length of the 

 hind margin. The central band is not irregular, as in C. nupta. On
