exaggerate, but this figure is fairly good. The figure by 

 Wilson in the ' Types ' is not good."

I have seen three specimens of this species from Victoria 

 (exact locality for his types was unknown to Waterhouse). 

 In appearance they are much like haemorrhoidalis but are 

 larger and with the prothorax triareolate only. The 

 figures given in the two publications quoted are not in 

 accordance with each other.

Metriorrhynchus limbatus, Wat. {Porrostoma), Trans. 

 Ent. Soc. Lond., 1877, p. 81, PI. II, figs. 88-91 ; 1878, 

 p. 180, genus 30; 111. Typ. Col. (Achras), p. 62, PI. 

 XV, fig. 7. 



There are several females before me which appear to 

 be referable to this species, only one of them, however, 

 agrees with the description in having " none (of the 

 costae) reaching to the apex " ; in the other specimens the 

 second and fourth costae are distinctly joined to the apex. 

 They vary in length from 3i to 4^ lines. 



In appearance the species closely resembles coenosus and 

 marginipennis ; from which, however, it may be readily 

 distinguished by the sculpture of the prothorax.

Only the female was known to Waterhouse ; the male 

 differs in being smaller with longer antennae, the joints of 



* 83a, 86a and 86b evidently do not refer to this species but to 

 dickrons. 



t Mr. Waterhouse gives " Australia " as locality for the type. 



X There is some confusion as to the numbers attached to the 

 figures of this species and inquinulus, as the latter are referred to as 

 82-86, the former 86-87. On examining the plate 86a, 866 and 87 

 all seem to agree with the description of dichrous.
