SPJIiEKOPHTHALMA. 391 



densely covered all over with long white hair ; the pro- and mesonotum coarsely punc- 

 tured ; the median segment with a gradually rounded slope, reticulated uniformly, 

 except that the spaces in the middle at the base are longer. The pro- and mesopleurae 

 are strongly punctured ; the metapleurse reticulated at the apex, the rest smooth and 

 impunctate. The petiole is gradually dilated to the apex, the apex strongly punctured ; 

 the other abdominal segments shining, impunctate, covered with long white hair. 

 Beneath, the petiole is bluntly keeled in the middle, the apex oblique, the sides with 

 some large punctures ; the other ventral segments impunctate, black, covered with long 

 white hair. The legs are covered with long white hair ; the long spur of the calcaria 

 fully three-fourths of the length of the metatarsus. The radial cellule is elongate, 

 narrow; the base of the radius straight, oblique, the apex curved; the recurrent 

 nervure is received shortly before the middle. 



S. marice may be easily known from the other two species of this section by the two 

 blunt teeth on the mesosternum.

Hab. Guatemala, Capetillo {Champion). 



The head very little narrower than the mesothorax, shining, impunctate, covered, 

 but not thickly, with long pale fuscous hairs ; the front ocellus with a distinct bordering 

 furrow, a shallow furrow running down from it ; behind, the head is rounded and is 

 there a little longer than the length of the eyes. The mandibles bear long white hairs ; 

 the tips piceous. The antennae are a little longer than the thorax, stout, tapering very 

 little towards the apex ; the scape a little curved, sparsely covered with pale hairs ; 

 the flagellum with an obscure pale down ; the third joint slightly longer than the 

 fourth and shorter than the first. The thorax is covered with long, white, soft hairs ; 

 the pro- and mesonotum rather strongly punctured, the lateral furrows on the meso- 

 notum distinct, reaching to the scutellum, which is strongly punctured and slightly 

 narrowed towards the apex ; the transverse furrow at the base of the scutellum deep. 

 The median segment has a gradually rounded, somewhat abrupt slope, and is strongly 

 reticulated ; at its base in the centre is a shining area, broader than long, and with a 

 sharp straight keel down the middle. The pro- and mesopleurse are strongly punctured ; 

 the metapleurse reticulated, impunctate and depressed at the base. The petiole has 

 the apex punctured, black, and shining, the base being rufous and covered, like the 

 apex, with long white hair ; at the apex it is twice the length it is at the base, but not 

 half the width of the second segment at the middle. The second segment is smooth 

 and impunctate, and is sparsely covered with long white hair ; the other segments are 

 more thickly covered with similar hair, the hairs, too, being longer; the terminal
