As noticed in the (lcscri[)tion, this is near ci/ialus, hnt 

 there is no oranjrc on the .second dorsal segment and much 

 more on the third. There are two strong s[)ines at the 

 apex of the intermediate tiljijc.

As Ilandlirseli points out, these are undonljtcdly sexes of 

 one species. The cilise on the tourth and fifth ventral seg- 

 ments are well develo[)ed ; the apical joint of the antcnuie 

 is curved; fore tarsi uot ciliated; intermediate tibi:e with 

 one long apical spur, the second spur more slender and uot 

 more tlian half as long.

Gorytes cijynorum, Turn. Proc. Zool. Soc. London, p. oOO (1008). rf". 



The apical joint of the anteunaj is not curved ; fore tarsi 

 not ciliate ; intermediate tibite with one long apical spine, 

 the second spine very short and slender; hind tibiae Avith a 

 few spines on the outer margin. The eilioe on the ventral 

 segments are not present in this s])eeies, possibly the long 

 hairs may have been rubbed off. 



In other points the species agrees well with the characters 

 of the group, and is undoubtedly closely related to the other 

 species.

(J . Eyes convergent towards the clypeus, separated at 

 the base of the antcnuie by a distance equal to the length of 

 the .second joint of the tlagelluni, which is about half as long 

 again as the third; a[)ical joints of the llagellum missing.
