436 Extract from Note Book regarding the Genus Paussus. [No. 138. 



I tried each elytron twice with precisely the same results ; during each 

 emission a faint acidulous odour prevailed, and the part being touched 

 with my finger, imparted that scent in rather a stronger degree to it. 

 Having taken a drawing of the insect, I directed my servant to remove 

 the microscope to another table, and in so doing, he unfortunately drop- 

 ped the specimen, and has thus brought my experiment to a close. 



Should the foregoing observations be considered worthy of publica- 

 tion, I shall be happy to transmit further extracts from my Note Book 

 as occasion may present, or apply myself to any other point of utility 

 in which my services may be deemed acceptable. 



I also take this opportunity of enclosing the copy of a very magni- 

 ficent species of Scarabeus, which I was so fortunate as to capture a 

 few days since. The form appears familiar to me, and I fear may not 

 be new to science ; but having no means of referring to books on the 

 subject myself, perhaps you can supply the required information ; at all 

 events, as it strikes me to resemble the general form assumed by the 

 equatorial Scarabsei, it will be interesting to know that this insect was 

 captured at an elevation of near 9,000 feet above the level of the sea, 

 having been taken on the summit of the Gogur range in Kumaon, and 

 was found feeding on the leaves of a tree unknown to me, but which I 

 believe to be a species of Maple. Length three inches, weight one 

 ounce, head and thorax a jet glossy black, the former furnished with a 

 large recurved horn in the form of a sickle, compressed at the base. 

 The thorax presents four protuberances, two above and two on the an- 

 terior margins. Scutellum black, elytra light chesnut brown, abdomen 

 and legs deep chocolate. The maxillaries curiously dentated at their 

 apices, and furnished with hairs. Maxillary palpi of four joints, the 

 last spindle- shaped and longest, the first conical and smaller than the 

 second. Mandibles, which are corneous and squared, jut out consider- 

 ably beyond the sides of the head ; they are also thickly set with hairs, 

 both on the internal and external sides, labial palpi very small. Antennae 

 of ten joints, the first conical, the next three nearly round ; the club is 

 composed of three leaflet joints, and the intervening ones are nearly cus- 

 piform, the tarsi are simple, of five joints, the last much produced. Hooks 

 nearly equal in length, and furnished beneath with a stiff seta, which near 

 its apex is split into a brush-like form. Taken August 17, 1842, 

 above Budlakhote, Kumaon. The drawing is taken of the natural size.
