Mr. J. Blackwall on some new species 0/ Araneidea. 187 



dibles powerful, conical, vertical, armed with teeth on the inner 

 surface ; they are of a red-brown colour. Maxillse short, strong, 

 straight, and broad at the extremity, which is rounded : lip nearly 

 semicircular, but somewhat pointed at the apex : these parts are 

 reddish brown, with yellowish brown extremities, the base of the 

 lip being much the darkest. Sternum heart-shaped, with small 

 protuberances on its sides opposite to the articulation of the legs ; 

 it is brownish black, with a longitudinal band of yellowish brown 

 in the middle, which diminishes in breadth to its posterior ex- 

 tremity. Legs long, provided with hairs and black spines ; they 

 are yellowish brown spotted with black; first pair the longest, 

 then the second, third pair the shortest. Palpi short and yel- 

 lowish brown, with the exception of the digital joint which is 

 red-brown ; the cubital and radial joints are short ; the latter is 

 rather the larger and is provided with some long hairs ; the digi- 

 tal joint is short, oval, convex and hairy externally, concave within, 

 comprising the palpal organs, which are moderately developed, 

 prominent, complicated in structure, with a curved black spine 

 at their extremity directed upwards, a projecting process at the 

 upper part, towards the inner side, and are of a dark red-brown 

 colour. Abdomen sparingly clad with hairs, oviform, somewhat 

 depressed, projecting over the base of the cephalo-thorax ; on the 

 upper part is a large, oval, leaf-shaped figure of a brownish gray 

 colour comprising a longitudinal row of small, black, slightly in- 

 dented spots on each side of the medial line ; the anterior part 

 of the leaf-shaped mark and a series of curved transverse lines, 

 diminishing in leng-th as they approach the spinners, are silver- 

 gray ; its margins are festooned and black, and an oval brown 

 spot occurs on each side of its anterior extremity ; following the 

 undulations of the black border is a narrow band of silver-gray ; 

 sides and under part brownish with a tinge of yellow and minute 

 blackish spots interspersed ; a broad black band extends along 

 the middle of the under part, on each side of which is a stripe of 

 yellow. Plates of the spiracles yellow. 



The spider from which the foregoing description was made was 

 discovered at East Lodge, Enfield, by Miss Gertrude Buller El- 

 phinstone, to whom I am indebted for it and for numerous in- 

 teresting species of Arachnida and Insecta ; indeed, the liberality 

 of Miss Elphinstone in transmitting to me specimens of living 

 spiders collected by her in Middlesex demands the tribute of my 

 grateful acknowledgments. 



At present I am acquainted with the male only of Epeira simi- 

 lis, which bears so close a resemblance to the male of Epeira calo- 

 phylla as scarcely to be distinguished from it except by the palpi 

 and palpal organs. By way of contrast, I shall briefly point out 

 some of the more remarkable particulars in which the latter dif-
