I have a species which seems in most particulars to agree with 

 Thorell's reticulata from Bell's Sound, Spitzbergen ; he describes his 

 as yellow-brown, mine is black, but he probably had his specimens 

 sent in sjiirit, after which they would very likely be yellow-brown. 

 What is more important, he describes his as reticulated with black ; 

 mine is reticulated, but it is with raised ridges of the same colour, 

 which ridges no doubt cast a shadow by oblique light. It is 

 therefore impossible to say for certain, without comparing specimens, 

 that it is the same species. I think it best to follow my ordinary 

 rule of giving the foreign author credit for the species where there 

 is a doubt ; meanwhile the description of mine is as follows : — 



Colour in life almost jet black all over. 



Cepludotliorax nearly half as long as abdomen, but being partly 

 overhung by the latter does not look so long as it is; broadly 

 conical until insertion of first pair of legs, thence nearly straight ; 

 tip of rostrum obtuse and blunt, the whole surface covered with 

 reticulations so fine that except under a considerable amplification 

 each reticulation appears to be a raised dot. A power of about 

 200 diameters shows each to be composed of a number of very 

 minute granules. There is a slight transverse mark about a third of 

 the distance from the tip of the rostrum like the edge of an 

 obsolete tectum. Near the abdomen the cephalothorax rises in two 

 rounded elevations, pressed together at the median line, but divided 

 by a sharp cut ; these bear the stigmata in the anterior part of 

 their lateral margin. The stigmatic hairs are very short and 

 small, they are almost triangular, the base of the triangle being 

 outward and the point prolonged to form a very short peduncle. 

 The interstigmatic hairs are short and thick, and curve inwards 

 horizontally so as nearly to meet. There are two fine curved 

 hairs on the rostrum. The coxae of the first two pairs of legs are 

 hidden below the body. The trochanters are very thin where 

 they are inserted, then they turn suddenly at an angle and become 

 greatly enlarged ; third and fourth joints square, about equal in 

 length, and together as long as the second ; tarsus nearly as long 

 as second joint, straight, truncated at the distal end. Third and 

 fourth pairs of legs tapering gradually, trochanters not enlarged. 

 The second, third, and fourth joints of each leg bear two or three 

 short, thick, curved hairs on each joint. All the tarsi are sparsely 

 provided with fine hairs. Labium very narrow and pointed. 

 Maxillffi long.
