84 SPOLIA ZBTLANICA. 



reaching beyond the middle of the segment, becoming gradually 

 narrowed to a fine point and continued to the apex by a keel ; its 

 base is irregularly longitudinally striated ; the depression border- 

 ing it closely strongly transversely striated ; on the outer side is 

 a long pyriform fovea. Suturiform articulation wide, closely, 

 strongly striated ; the furrow on the apex of the third segment 

 and on the base of the fourth are striated ; on the apex of the 

 fourth is a smooth furrow ; the third segment is strongly and 

 closely striated, but not so strongly, as the second ; the fourth is 

 more finely and closely striated. Hind tibiae and tarsi densely 

 covered with black hair. Apex of sheaths of ovipositor white. 

 Apical abscissa of radius curved, slightly longer than the basal two 

 united ; received in the apex of the first cubital cellule, clearly 

 distant from the first transverse cubital nervure. 



20. — Iphiaulax ernesti, sp. nov. 



Head and thorax red ; the four front legs yellow, their coxae 

 tinged with rufous, hind legs fuscous black ; wings fuscous, 

 hyaline, highly iridescent, the nervures and stigma black, 9. 



Length 8 ; terebra 12 mm. 



Peradeniya, October. 



Face rugose, thickly covered with long fuscous hair. Temples 

 obliquely narrowed. Antennal scape rufous, about f ourtimes longer 

 than thick, of equal width throughout. Front deeply furrowed. 

 Middle area of first segment with two keels, which unite into one 

 shortly beyond the middle ; its sides margined and there is a 

 curved keel which runs from the central two before they unite ; 

 the lateral furrows with some scattered transverse keels. The 

 area on the second segment becomes gradually narrowed to a fine 

 point shortly beyond the middle ; the base finely, distinctly 

 striated ; the depression bordering it has some transverse, not 

 very distinct, striae ; outside it are four curved longitudinal striae ; 

 the fovea on the outer side is rounded at the apex and is of equal 

 width. The third segment is closely, strongly longitudinally 

 striated ; the suturiform articulation, the furrow at the apex of the 

 third and at the base of the fourth are striated ; that on the apex 

 of the fourth is smooth ; there is a J-shaped striated furrow on the 

 sides of the second segment at the base ; the basal two-thirds of 

 the fourth segment is finely, longitudinally striated. 



A much smaller and more slenderly-built species than /. greeni; 

 the fore legs are yellow, not rufous ; the antennal scape is more 

 slender and does not project at the apex, and the first and second 

 abdominal segments are finely sparsely striated, not coarsely 

 striated and reticulated.
