ants' nests for about a mile on both sides of S. Sampson's harbour." 

 And, in reply to a letter in reference to the habits of this species and 

 R. Tomlinii, Newst., Mr. Tomlin sent the following interesting com- 

 munication : "I have visited Moulin Haet, the original locality of B. 

 Tomlinii, and secured a supj)ly of what I talis to be that species. 

 They live high up on the cliffs in the nests of a largish black ant, 

 though I found some under stones where there was never an ant to 

 view. On the other hand, the species I sent last week (iJ. europcua) 

 lives under atones, loithin a few yards of high-water mark ; the ant is 

 different, and though there are nests of two or three other species of 

 ants living all along the shore as plentifully as this kind, yet the 

 Coccid never favours their nests, as far as I could discover (and I 

 made a point of ascertaining this). The ants show great eagerness 

 in carrying them off, and are very reluctant to relinquish their burden. 

 What strikes me particularly about this insect is the way it occurs on 

 the under surface of the bare stones. I turned up one yesterday 

 with between 40 and 50 of all sizes dotted about the stone. It is 

 infrequent in the actual nest on plant stems, though I have secured an 

 example of this habitat to send you." August 26th, 1896. 



KlPERSIA TUAIIDA, n. sp. 



9 adult ovate, tumid, and extended behind. Antennae (fig. 1) of 7 joints ; the 

 last longest and fusiform ; 2, 3, and 4 shorter and subequal ; 

 5 and 6 shortest. Mentum biarticulate ; filaments short. 

 Legs rather long, slender; tarsi short ; a little more than a 

 third the length of the tibise ; digitulcs absent, but they 

 may have been broken away, as a slight scar was traceable 

 at the point where they are usually attached. Anal lobes 

 obsolete ; and in the specimens before me there are no hairs 

 to indicate the position of the lobes. Anal ring large, with 

 six long hairs. Dermis above almost hairless ; but with 

 many circular spinnerets placed very close together. 



Long., 275— 3-50 ; wide, 1-75— 2-50 mm. 

 ? , second stage. Mentum biarticulate ; filaments a 

 little longer than mentum. Antennae (fig. 2) of 6 joints ; 3 and 6 are longest ; 2 

 as long as 4 and 5 together. Anal lobes minute. The latter and each abdominal 

 segment at the margin with a few minute spines. 



Hah. : Flemcen, Algeria, with Gamponotus Etlii, var. concolor, 

 For. M. Forel collector. 



The seven-jointed antenna?, and the tumid character of the body, 

 are the distinguishing features of this species. The absence of hairs 

 on the anal lobes may be of importance; but my series is much too 

 small to be certain of the constancy of this character.
