Urostylis striicornis, Scott. 



Taking the species to be represented by a portion of 

 the diagnosis, viz., 1st joint of the antennae with a fuscous 

 streak exteriorly, the colour certainly varies from ochra- 

 ceous to greenish. I consider the species to be variable 

 within the limits of the superficial characters given for the 

 three described forms, U. striicornis, U. annidicornis, and 

 U. zvestwoodii, Scott. The describer, however, states that 

 he has found structural characters in the genital segments 

 to separate his species ; and though not questioning his 

 decision, as I have not the material for verification, I am 

 still dubious whether dried specimens afford sufficient 

 material for separating species on the character of the 

 last genital segment having "an external spoon-shaped 

 process," as compared with being "broad, flat, slightly 

 dilated at the apex," or on the contrary " aculeate," 

 especially when the species are practically indistinguish- 

 able in other respects. 



Megymenum tauriformis, n. s. 



Very dark fuscous, with bronzy reflections ; antennae 

 with the 2nd and 3rd joints non-dilated, but somewhat 

 flattened and channelled, the 3rd and 4th about equal in 

 length, the last reddish ochraceous, with the base fus- 

 cous ; head with two distinct conical spines on the lateral 

 margins a little in front of the eyes, the posterior spine 

 minute ; pronotum with an anteriorly produced conically 

 dentate angulation on the anterior lateral margins at a 

 little distance from the eyes, lateral margins truncate, 

 with a short central spine, their anterior angles truncate, 

 their posterior angles rounded, the disk uneven and 

 crenulate, with a distinct rounded callosity near centre 

 of anterior margin ; scutellum of ordinary structure, and 

 as in M. subpurpurascens, Hope; membrane pale obscure 

 ochraceous, the whole disk darker and sometimes fuscous ; 

 margins of the abdomen broadly and obtusely dentate ; 

 legs concolorous, tarsi somewhat castaneous. Long. 

 1S| — 15 mm. ; greatest pronot. exp. 7 — 7i mm. 



Hab. Kashiwagi, Nara. 



The structural characters of the non-dilated 2nd and 3rd 

 joints of the antennae, with the 3rd and 4th joints of equal 

 length, assign to this species a position in the subgenus 

 Pissistes, Stal ; whilst the curved and anteriorly directed
