tribe, and is itself typified especially in the genera ^gratis, Mamestra, 

 Polia, &c.: 2. Fusiformes, larva attenuated almost equally towards 

 both extremities; typical genera, Liihosia, Eulepia, and Deiopeia; 

 possibly also many of the Tinece may be here included on further in- 

 vestigation: 3. Fasciatce, larva cylindrical, thinly scattered with short 

 bristly hairs, abruptly terminated behind, and, as far as has been ob- 

 served, uniformly marked with transverse bands of a briUiant, mostly 

 yellow, colour; this form appears to be strictly oriental, and will be 

 illustrated in the progress of the work : 4. Ciliatce, larva with the two 

 anterior abdominal feet by far the smallest, and with the last segment 

 but one rising in a protuberance which is terminated by two points ; many 

 of them are fringed along the sides of the body ; typical genera Catocala 

 3.ndJ[brostala: 5. Semigeometree, larva with only twelve feet, bending 

 the back in walking ; the type is the genus Plusia, Hiibn. The passage 

 from this to the first stirps of the succeeding tribe is most gradual and 

 easy. 



The remaining tribe, the PhaldenidcB also exhibits among the larvse of 

 the insects which compose it five types of form, the precise limits of some 

 of which require, however, more detailed and accurate investigation. 

 They are 1. Seminoctuales, larva with twelve feet, agreeing in this 

 respect with the last stirps of the preceding tribe, but approaching in 

 the mode of undergoing its change to the next stirps : typical species, 

 Phalcena margaritaria, prasinariafBiidfasicaria: 2. Geometrce, larva 

 with only ten feet; their movement in walking being comparable to a 

 loop: 3. PyralidcB: 4. Tortrices, larva with sixteen feet, contort- 

 ing or rolling the leaves on which they feed, and in which they undergo 

 metamorphosis: 5. Tinece, in which the larvae are much diversified, 

 having sixteen, fourteen, or even eight feet ; the revision of this group 

 is absolutely required, nearly the whole of the smaller Lepidoptera 

 having here been thrown together vnthout examination. Some of its 

 species, possessing an affinity with the Seminoctuales, vnll probably lead 

 back again to the point in which the circle of Phalcsnidce is completed. 



The circular succession of the affinities appears theretore capable of 

 being readily established in the last of these tribes ; but Dr. Horsfield has 

 not attempted to trace it in the three preceding; nor is it yet fully given 

 as regards the first. The circle which embraces the whole order is shown
