8. Smicra spinicoxus sp. n. 



Black, a mark, twice longer than wide, narrowed below, on the sides 

 of the lower half of the frontal depression, a curved line on the apex 

 of the pronotum, a conical mark, the narrowed end at the base, on the 

 sides of the apical half of the scutellum, two lines on the middle of the 

 mesonotum, along the furrows, the upper part of the abdominal petiole, 

 two transverse conical marks, almost united on the centre of the apex of 

 the second segment, a large semi-circular one on the fourth, a smaller 

 one on the last, with a fuscous line down the middle of the apical two- 

 thirds, the four anterior knees, the femora and tibia below, a line along 

 the top of the outer side of the hind coxae, extending from the base to 

 the apex, becoming slightly wider towards the apex, dilated downwards 

 on the apical part to the teeth, the incision longer than wide counting 

 from the top to the bottom, and slightly narrowed at the top, leaving a 

 semi-circular black mark on the lower apical part and continued along 

 the top of the inner side, there being below it a semi-circular mark, clear 

 yellow ; the hind tibiae are of a darker yellow behind and are infuscated 

 in the middle, the hind tarsi are yellow like the others. There are eight 

 femoral teeth ; the first and third are large and widely separated, the 

 second minute ; the others short, stumpy, rounded. Hind coxae as long 

 as the femora, armed with a minute tooth near the apex above. Wings 

 almost hyaline, the nervures black, <? . Length 6 mm. 



Frontal depression smooth, with a stout keel down the centre; the 

 sides with curved, clearly separated striae ; face more finely transversely 

 striated, the striae turned up laterally. Clypeus smooth. Thorax with 

 thimble-head like punctures, which are stronger and more clearly 

 separated on the scutellum. Apex of scutellum with a broadly rounded 

 raised margin which is not depressed in the middle. Metanotum 

 coarsely irregularly reticulated. Base of propleurae closely rugosely 

 punctured, the apex smooth, the depression irregularly striated. Meso- 

 pleurae coarsely rugosely punctured, almost reticulated. Metapleurae 

 more coarsely reticulated than the metanotum. Abdominal petiole 

 about two-thirds of the length of the hind coxae and not much shorter 

 than the rest of the abdominal segments united. Head, thorax, and 

 legs covered, not very densely, with white pubescence. The third and 

 fourth joints of the antennae are almost equal in length.

9. Smicra mendozsensis sp. n. 



Yellow, slightly tinged with rufous, the flagellum of antennae fuscous, 

 darker above ; the mandibular teeth, a narrow line down the centre of 

 occiput, a broader one round its lower edge, a narrow line round the 

 base of mesonotum, one down its centre, one along the sutures, a 

 broader one of almost equal width down the middle of the scutellum, 

 one, narrowed at the top, on the lower three-fourths of the base of 

 mesopleurae in the suture, a wider spindle-shaped line on the apical
