Nov. 5 are the yellowish dry-season forms ; while 2 of 

 Nov. 5-9, and 3 of Dec, 26-31 are the black-and-white wet 

 form. Of these latter a pair taken in cop. on Dec. 26 were 

 resting with expanded wings on the under side of a large leaf. 



Among the moths collected at Lnlangurn was a most 

 interesting series of individuals hitherto regarded as belong- 

 ing to four different species of the Pterothysanid genus 

 Hibrildes. The occurrence of all together in the same locality, 

 and almost certainly on the same small kopje top, strongly 

 confirms the conclusion at which Sir George Hampson has 

 arrived, that all are forms of a single species. Of the 11 

 moths — all taken Dec. 1-31, 1917 — 3 are white males (norax, 

 Druce) ; 3 are white but strongly veined males (venosa, Kirb.) ; 

 3 are Acraeoid females (crawshayi, Butl.) ; 1 is the form 

 with orange-ochreous hind-wings like crawshayi but fuscous 

 fore-wings with a white subapical bar (ansorgei, Kirb.). On 

 this Capt. Carpenter had noted " On wing incipient Aletis or 

 chrysippus mimic." The eleventh specimen is an interesting 

 variety of ansorgei with a rich orange-ochreous subapical 

 fore-wing bar. 



" After butterflies come moths, and that brings me to the 

 subject of insects which come to light. Moths are almost the 

 only things that don't come here — I have never seen so many 

 insects at light. The most curious feature is the predomi- 

 nance of different families — or even species — on different 

 nights. Sometimes the table is covered with wood-borers of 

 numerous forms; on other nights quite small Carabidae; then 

 large and annoying Melolonthidac predominate ; on another 

 night Elateridae, sometimes large, sometimes small; then 

 small Melolonthidac or Copridae, Manfidae, Blattidae, Myr- 

 meleonidae, a few Diptera, Hemiptera, Longicornia, Weevils, 

 water beetles of different groups, Gerris. Quite large and 

 very odoriferous Carabidae, Cicindelidae, and even a beautiful 

 Dragonfly and large Cicadas have all come. Perhaps on one 

 night several species of an insect will come which is never 

 seen again. Indeed Crustacea. Myriapoda, and Arachnida 

 are almost the only Arthropods that have Dot been attracted ! 

 Consequently J have made a large collection for the Brit. 

 Mus., and send you duplicates whenever possible. I have
