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



minute vesicles, resembling the eyes on the anterior extremity of the 

 scorpion, of a resinous color and lustre. The antennae are composed 

 of two joints, the last very large, somewhat irregular, approaching 

 in form to navicular. The edges of the upper margin present the 

 appearance of a screw, both edges meet posteriorly, and form a slightly 

 recurved spine projecting from the basal internal angle. The club 

 when viewed at the side, resembles a butcher's cleaver. The thorax 

 has its upper portion cardiform, and appears as if fitted into a cavity of 

 the lower part, which latter also presents a crenulated edging extend- 

 ing the whole breadth of its centre. The margins of the thorax, head, 

 and particularly the screw-formed edging of the antennae, appear 

 translucent, and in color very much resemble shell lac. The eye is 

 kidney-shaped, but appears round when viewed from above. The palpi 

 are short, and not very salient. The abdomen is turned and gibbous 

 near the cloaca, and its extremity is furnished with two large bundles 

 or brushes of densely set golden colored hairs, having also a vitreous 

 appearance, and which are only rendered distinguishable by being dis- 

 turbed with the point of a pin or such like implement ; these hairs I 

 found so very closely arranged, that even with my greatest care in try- 

 ing to separate them, I never once succeeded in singling out a fibre : 

 they always remained in bundles, or in the form of a moistened paint- 

 ing brush. I must not omit to state, that the character of this curious 

 appendage was (I believe) first made known to the world by W. W. 

 Saunders, Esq. ; at all events my observations on it were induced from 

 what I read in his account of this Paussus, published in the 2nd vol. of 

 Entomological Transactions. 



The elytra which are black, with their anterior and posterior margins 

 of a pinkish brown, have their surface closely covered with silvery 

 hairs, and near their posterior external margins the curious folicle 1 

 have already observed in No. 3, is very apparent. The abdomen is of 

 a dirty yellow or Isabella color, approaching to light umber, and near 

 the penultimate segment beneath, there are a pair of spines which 

 curve slightly outwards, for what intent and purpose I cannot conjec- 

 ture. Breadth of elytra and abdomen equal throughout. Tarsi evi- 

 dently of five joints, the last longest. 



Note. — I tried all I could to induce this specimen to crepitate, with- 

 out success. Probably its battery had been expended in its struggles
