pany, who from the sensation she felt beneath the finger, concluded 

 she had mistaken a small Brachinus for a Paussus, and the skin of 

 which, bore evident marks of the displosion, I have been induced to 

 make these experiments, and the results have been as above stated. 

 Captured No. 5 at a quarter after nine p. m. 



Note.-^-August 29, 1841. — All the marks off my right hand. 



Note. — September 3, 1841. — I have now lost all the stains on the 

 fingers of my left hand, which I received in the experiments performed 

 on Paussus, No. 5, by which it appears, that those of the left hand have 

 remained 18 days, or 6 days longer than those on the right. This is 

 singular enough, and I can only attribute the loss of the marks so much 

 earlier in the right hand fingers to attrition, and more constant use, 

 as the stains left were certainly much deeper in the three first trials 

 than in the latter ones, and where I used the first, second, and third 

 fingers of my right hand respectively. 



No, 6, Fig. 6. — Sultanpore, Benares, September 5, 1841. — This 

 Paussus has the thorax somewhat similar to that part of No 1 which 

 I captured at Mhow, but in other respects differs considerably. 

 Length 6-20th of an inch. The antumae are composed of two joints, 

 of which the last is very large, and in the form of a wide-mouthed 

 cornucopia, being attached to the first at its basal angle. The mar- 

 gins of the upper side are slightly crenulated, and the upper surface 

 is rather deeply excavated, giving this part a cuspiform appearance. 

 Anterior and posterior margins compressed, the latter produced into a 

 blunt recurved tooth. The sides of the club are faintly striped with 6 

 grooved bands ; the eye when seen from above appears round, of an ir- 

 regular oval shape when viewed from the side. Head trigonal, depressed 

 with a marginal excavation, but no groove on the upper part. The 

 thorax appears as if composed of two portions, the anterior being 

 angulated, and forming a rather sharp spine on each side, with its base 

 inserted in the posterior part. This latter portion is crenulated, with 

 the exterior margins produced and rounded ; a sulcus in the form of a 

 bracket crosses the centre. The elytra are black, broadly patched 

 anteriorly with brownish sienna, the posterior margin has a faint unde- 

 fined line of the ssme color, which blends into the general black of the 

 wing cases. The folicles at the exterior margin of the elytra posteri- 

 orly are much produced, and close to them on each side is a very
