armatures in the Hynunopterom genua GoUctcs. 3t) 



16. Dorsal surface of abdomen peculiar, showing in 



places a sort of irregular transverse rugulosity 

 or striolation together with numerous very 

 shallow punctures. The latter vary in shape 

 and size, and have rather ill-defined margins. 

 They are partly "elevated," and sometimes 

 become almost confluent transversely. The 

 exti'eme apices of the segments are smooth 

 and whitish. Their discs are clothed with 

 pretty long suberect hairs. The colour 

 of the pilosity seems to be mainly cinereous, 

 that on the thorax rather fuscous than 

 fulvous (but all my specimens are much 

 faded). The sixth ventral segment has a 

 well-marked central carina. The labrum is 

 scarcely tuberculated or foveated. The 

 anterior and intermediate tarsi seem particu- 

 larly long and slender, scarcely half as broad 

 as the post(!rior. The insect is rather large, 

 circ. V6 mill. long. The wings sometimes 

 (but not always) evidently with a yellowish 



stain 35, C(iriiii(/vr, Perez (!'=: 



coflaris, Dours). 

 Punctures of abdomen above either large and 

 strong, or, if fine, at least pretty deep and 

 well-defined (circular) upon a smooth ground ... 17. 



17. Discs of intermediate abdominal dorsal plates 



clothed with longish sub-erect hairs. Inter- 

 mediate joints of tarsi postici considerably 

 dilated, cordiform, at least half as broad as 



long (PI. IX, 59, (30, 61) IS. 



Discs of intermediate dorsal plates very shortly 

 pubescent or naked. Intermediate joints of 

 tarsi postici narrower, evidently not half as 

 broad as long (PL IX, 62, 63) 21. 



18. Intermediate joints of tarsi postici broader 



than long. Wings faintly clouded. Discs of 

 abdominal dorsal plates strikingly hirsute. 

 A large Mediterranean sp. 12-13 mill. long... 11. abcillci, Perez. 

 Intermediate joints of tarsi postici not or 

 scarcely as broad as long. Species smaller, 

 and all occurring commonly in northern 

 districts 19. 



19. Puncturation fine and sparse. Fasciw narrower, 



the hairs forming them scarcely half as long 

 as the erect hairs on the disc of second 

 segment. Sixth ventral plate dentate later- 

 ally and not carinated in the centre (PI. 



IX, 50) 18. 'y«c/M(0(/?.s Smith. 



Punctures much closer and stronger. Fasci;e 

 wider, their hairs about as long as the erect 

 pilosity. Sixth ventral plate evidently cari- 

 nated in the centre (PI. IX, 53) 20. 



20. Second joint of tarsi iJostici (PI. IX, 60) more 



produced and dilated at the apex exteriorly, 

 making the very oblique apical margin as 

 long as the interior. Antenu;e longer. 

 Fascia; of a purer white. (Pilosity of body 



and legs a little shorter and less copious) ... 19. ^;("c/s(/(/»iff, Thorns. 

 Second joint of tarsi postici (PI. IX, 61) less 

 dilated and produced, the apical margin is 

 therefore less oblique and evidently shorter 

 than the interior. Fasci;e with a creamy 

 tinge. Antenme shorter 12. /ot^'c'!*^', Kirby.
