dots ; but the dots quite as often are closely approxi- 

 mated, or touching, in one direction but not in the 

 other, and then they form lines, which may be straight, 

 or of twisted, zigzag, or irregular forms, and may be 

 confined to one part of the notogaster, e. g. the median 

 portion (the dots being detached on the lateral) or the 

 hinder portion, &c. ; or the arrangement of the lines 

 may be different in different parts, they may even form 

 a hexagonal reticulation ; but in all instances that I 

 have seen the lines when examined with a high power 

 show their origin from coalesced dots. There are six 

 longitudinal rows of thick, spatulate, yellowish -white 

 hairs on the notogaster. Ventral surface not so rough 

 as the dorsal but somewhat similar in markings. 

 Genital and anal plates near together, occupying the 

 whole length of the ventral plate, of about equal width ; 

 the genital almost square, slightly widest anteriorly ; 

 the anal long, somewhat narrowed posteriorly, with 

 three pairs of hairs at the sides. 



Nymjph. 



I have not had an opportunity of breeding this 

 species and cannot say with certainty what it is ; but 

 Mr. Bostock is of opinion that a nymph apparently 

 belonging to the genus Hermannia^ which he found in 

 company with the adult in the singular locality where 

 his specimens were obtained, is that of H. nodosa. This 

 is probable, and is rendered more so by the fact that 

 I have a specimen of a similar nymph found in a locality 

 where I also found the adult of this species, but the 

 difference of which from the nymph of H. reticulata 

 I did not observe at the time of capture. This nymph 

 is extremely like that of H. reticulata^ but may be dis- 

 tinguished from the ordinary form of it by the abdo- 

 men being divided into three parts by a light, some- 

 what depressed linear marking, the shape of an inverted 

 Y , the stalk of the letter proceeding from the centre of
