The <£ of this species is known at once by the spine at 

 the base of the anterior femora (beneath). The £ which 

 I have assigned to it agrees with it in size and general 

 coloration, and has the post-scutellum rather sharply 

 elevated as in the $. It lacks the long hairs of conso- 

 brinus and rotundigastcr, but has the yellow band of the 

 second abdominal segment dilated at the sides as in those 

 species, although more distinctly so. The scutellum and 

 post-scutellum are entirely black. 



Odynerus {Hoplopus) deceptor, n. sp. 



0. variegato simillimus, ab illo mas coxis intermediis nigro 

 spinosis facile distinguitur, femina, angulis propodei subproductis, 

 segmento secundo abdominis latiori subtus testaceo, minus crebre sed 

 obsoletius punctato aegre distinguenda. 



Resembling 0. variegatus in colour but at once recognizable by the 

 black spines on the intermediate coxaj of the ^ and the very largely 

 laterally produced bands of the abdomen which on the 1st and 2nd 

 abdominal segments leave only the central basal portion black. In 

 the $ (?) of this species the lateral angles of the propodeum although 

 not acute are more produced than in variegafais, the 2nd abdominal 

 segment is wider in proportion to the 1st and on its under-side is 

 testaceous, more shining than in variegatus less closely and more 

 obsoletely punctured, but only having one example of this ? I am 

 unable to say how far these characters are constant. 



£ . Head and thorax black, closely punctured, dull, clothed rather 

 sparingly with greyish-brown hairs, clypeus yellow, shining, deeply 

 and semieircularly incised at the apex, labrum yellow, mandibles 

 black, spotted with yellow at the base, a somewhat straight yellow 

 spine projects from the gena on each side of their extreme base ; 

 this spine is slightly curved towards the apex and viewed laterally 

 appears nearly truncate, a transverse tubercle between the antennae 

 and the scape in front testaceous, spire entirely black, pronotum with 

 a ferruginous band not extending to its posterior angles, anterior 

 angles slightly produced and sharp, tegulai ferruginous, wings smoky, 

 especially along the costal margin, scutellum slightly raised, post- 

 scutellum nearly perpendicular, ferruginous, slightly concave and 

 very shining, sides of the propodeum obtusely angled, its concavity 

 dull, diagonally striate, widely channelled, with a narrow longi- 

 tudinal carina running along the bottom of the channel— legs
