LXI. Notice of the Geological Features of a Route from Madras 

 to Bellary , in April and May 1822. By Capt.W. Cullen, 

 of the East India Company's Artillery service*. 



T BEG to submit to the Society an attempt to describe the 

 * geological features of a route which 1 lately passed over 

 from Madras to Bellary. It accompanies a small collection 

 of specimens of the prevalent rocks, and a barometrical sec- 

 tion, which combined will, I hope, assist in affording some idea 

 of the nature of the tracts in question. 



The high road to Bellary was followed as far as Cuddapah ; 

 but from thence going north, by Chinnoor Nundialpett Poon- 

 namila to Iddamacul, my route, from the last-mentioned vil- 

 lage, lay nearly west by Giddeloor, over the Nulla Mulla range 

 of hills by the Nundi Kunnuwi Ghaut f, by Ban aganap illy, 

 Piaplee, and Gootty, to Bellary. A great proportion of this 

 route must, in favourable weather, be as beautiful in point of 

 scenery, as it is ricli in geological interest ; but at the period 

 of my passing (the latter end of April and beginning of May), 

 the excessive heat had checked all vegetation, and afforded but 

 little inducement for excursions in quest of mineralogical spe- 

 cimens. 



Referring the route to Arrowsmith's large map, which is 

 sufficiently correct for the present purpose, it will be observed 

 to offer an obvious distribution into five portions, each of them 

 characterized by distinct geographical features. 



First. The plain open tract from Madras to Naggery. 



Second. The narrow mountainous belt extending from Nag- 

 gery to the neighbourhood of Cummum. 



" Ino, Leach. — Antennce gradually thickening from the base to near the 

 apex, straight, bipectinated, or simple, with the interior edge subserrated : 

 palpi short, not reaching beyond the clypeus, densely clothed with scales : 

 head, thorax, abdomen, and femora, thickly covered with scales, rather elon- 

 gate on the former. Larva scaly, depressed j head small : pupa with long 

 wing-cases." 



" The species are known from the Anthocerae (Zygaenae) by the form of 

 the Antennae, which are not curved, but nearly straight, and become gra- 

 dually thicker as they approach the tip, which is again slightly attenuated ; 

 the males have this part bipectinated, and the females simple, but ser- 

 rated beneath ; the species (of which there are several on the continent) 

 are all of rich tints of light green, blue, or brownish, and immaculate." — 

 Must. Brit. Ent. (Haustellata), vol. i. p. 105. Stephens gives only one species, 

 (Statices, Linn.) as decidedly British : that considered as Globularice, Hiibn. 

 having, on examination, proved to be referable to Ino Statices, var. /3. 

 He conceives, however, that it is extremely probable that Ino Globularice 

 may occur in England.

f Kunnuwi is Kanarese for Ghat. Nundikunnuwi means, therefore, 

 Nundi Ghat.
