 F. Smith, MSS. 



This genus is formed for the reception of those species which 

 differ from the typical S2)hex in the following particulars. 



The second submarginal cell is narrowed towards the marginal 

 and receives the first recurrent nervure towards the base; the 

 second recurrent nervure is received by the third submarginal cell, 

 a little within ; the legs elongate, the tarsi densely spinose ; the 

 claws bidentate, the anterior pair with dense long cilia outside ; the 

 abdomen ovate, abruj)tly convex at the base, pointed at the apex. 



1. Harpactopus crudelis, n. s. PI. VI. fig. 4. B.M. 



Female. Length 12 lines. — Black : the face covered with 

 silvery pubescence, and sprinkled with stiff bristly hairs; the 

 cheeks and margin of the vertex have a black pubescence ; the 

 clypeus with a notch in the middle of the anterior margin, and 

 having a longitudinal impressed line not quite extending to its 

 base. The prothorax covered above with silvery pubescence ; 

 the mesothorax and scutellum roughly punctured, the latter is 

 rugose-striate behind ; the metathorax thickly clothed with black 

 pubescence, and coarsely rugose ; a raised acute tubercle in the 

 middle of the post-scutellum, behind abruptly truncated; the 

 legs elongate, stout and thickly spinose, particularly the tarsi ; 

 the anterior pair strongly ciliated outside ; the claw-joint large, 

 and set with strong bristles ; wings yellow-hyaline, their outer 

 margins hyaline, the apex of the anterior pair fuscous. Abdomen 

 ovate, the apex acute, very convex, abruptly so at the base, and 

 very smooth and shining.

2. Harpactopus tyrannus. B.M. 



Female. Length 12 lines. — Black : the face has an indistinct 

 silvery pubescence, that on the cheeks is black ; the face thickly 

 covered with stiff black hairs ; the vertex rather finely punctured. 

 Thorax rugose-punctate ; the scutellum longitudinally strigose 

 behind, sparingly punctured in front and slightly depressed in 

 the middle ; the post-scutellum with an elevated compressed 

 tubercle in the middle ; the metathorax abrujitly truncated, and 

 covered with long sooty-black pubescence ; the legs as in H. cru- 

 delis ; wings dark fuscous, their apical margins broadly subhya- 

 line. Abdomen smooth and shining, the base subtruncate or 

 abruptly elevated, very convex, acute at the apex.
