in July, and in Leigh Woods, near Bristol, at the end of May. 

 Mr. Kirby took it at Coddenham, near Needham Market, Suffolk, 

 but only the female. In his Monograph he has described the 

 apical spines of the tibise as being black ; this is an oversight : his 

 own typical specimen has them rufo-testaceous. This circumstance 

 has, I believe, caused both Schenck and Thomson to mistake his 

 species, who accurately describe the sexes of 0. leucomelana under 

 another name. 



11. Osinia spinulosa. 



0. atra, cinereo subvillosa, scutello bidentato, ventre lana ferru- 

 ginea tecto ; ano maris inflexo, spinuloso ; ventre basi cornuta.

Female. Length 3-3| lines. — Black, closely punctured, the head 

 and thorax most strongly so ; the anterior margin of the clypeus 

 truncate ; the face with cinereous pubescence on each side of the 

 clypeus, and above the insertion of the antennae is a tuft of pale 

 fulvous. Thorax thinly clothed above with pale fulvous pubescence, 

 that on the sides and also beneath is more or less cinereo\xs ; the 

 scutellum rounded posteriorly, and armed on each side with a small 

 acute tooth ; wings subhyaline, their apical margins clouded, the 

 nervures nigro-fuscous ; the legs with pale fulvous pubescence, 

 that on the first joint of the tarsi beneath bright fulvous ; the claw- 

 joint rufo-testaceous. Abdomen ovate and shining, clothed beneath 

 with bright ferruginous pubescence. B.M. 



Male. Length 3-3| lines. — Black, punctured as in the other sex ; 

 the face with yellowish white pubescence below the antenna). 

 Thorax sparingly clothed with pale ochraceous pubescence ; on the 

 sides, beneath, and on the legs it is cinereous ; the apical joint of 

 the tarsi ferruginous ; wings as in the female. Abdomen incurved ; 

 the apical margin of the sixth segment denticulate, that of the 

 seventh with an acute tooth in the middle; the basal ventral seg- 

 ment armed with a stout curved spine. B.M. 



This is a local insect, apparently preferring chalky districts ; it is 

 found all along the coast between Lower W aimer and Dover ; plen- 

 tifully at Jungsclown, in July and August. It is not uncommon at 

 Luccomb Chine, Isle of Wight, and has been taken at Croydon and 

 Reigate ; it frequents the hawkweed, wild scabious, and the thistle. 

 The pubescence is frequently almost entirely cinereous above. The 

 specimens described are in fine condition.
