the opener parts, rarely settling and rarely coming within reach of the 

 net ; the gigantic Caligos always settling on tree trunks in the shade, 

 and if disturbed flying a short distance to rest again in the same 

 manner, Paphia, Opsiphanes, Gynaecia, Epicalia, Catagramvia, and 

 Protogonius, often on excrement, &c., on the ground, and not seen till 

 nearly trodden upon' when they fly off wildly to settle on some tree- 

 trunk or leaf ; the beautiful transparent- winged GallitcBra, seen by 

 its rosy-pink patch for a moment only as it crosses the path ; a good 

 many species of Satyridce in the dense undergrowth, flying very near 

 the ground ; various EuptycMce, Mesosemia, and other Erycinidce, 

 many SeliconiadcB {Heliconius, Itliomia, Mechanifis, &c.), the trans- 

 parent-winged Leptalis, so like Ithomia, many Sesperidce, Apatura, 

 Seterochroa^ and other Nymphalidce, and others will be found in the 

 opener parts of the forest ; Castnias, flying wildly, Olaucopis and allies 

 (some of which, while on the wing, are absolutely indistinguishable 

 from wasps) flying about the low undergrowth, various day-flying 

 Heterocera, some of which so mimic Heliconius, Ithomia, and other 

 butterflies, as to constantly deceive the collector ; various LithosicB, 

 Notodontee, Oeometrcs, and Pyrales, will occasionally fly out or fall on 

 to the beating net ; of the Micros, very few species will be seen beyond 

 an occasional Tinea or plume. 



The Coleopterist will probably be very much disappointed at first, 

 plenty of butterflies may often be seen when scarcely a beetle is to be 

 found ; general beating, as a rule, is not productive, unless on the 

 margin of new clearings, or where the sun penetrates freely ; the 

 great thing is to find a new clearing in the forest, and these to any 

 extent are only made by the natives in the dry season (December or 

 January, so as to burn in March) — not by any means the best time 

 for the collector ; however, now and then, one does find a clearing or 

 freshly fallen trees, then is the time, almost before the trees are down, 

 beetles begin to appear — Longicorns (I have taken perhaps 100 species 

 in one clearing, by constant hunting day after day for a fortnight), 

 Elaterid(B (Semiofus, GJialcolepidius) , Anthribidce, BrentJiidce, Trogosi- 

 tidce (TetnnocJiila), Hisferidcs {Hololepta, Tryponceus), Scolytidce (es- 

 pecially Platypus), Golydidcd {GoJydium, Auboniuiii), various Cleridce, 

 Lycidce, Biiprestida, &c. The best way to find many of these, 

 especially the Longicorns, is to crawl over the fallen trees the best 

 way you can and examine very carefully the shady or under-side of 

 the trunks and branches, even to the smallest twigs, many of the 

 smaller Longicorns, &c., are so active, taking to wing directly they 

 are approached, that it is little use boating for them, diligent search-
