HEMITELES. 255 



the scutellum, the postscutellum, and two large longish marks on the metanotum, 

 yellow. First abdominal segment black, yellow at the base and apex ; second segment 

 yellow, with a large black transverse band at the base, the band narrowed at either 

 side behind ; the third to the fifth segments black, broadly yellow at the apex ; the 

 apical segments entirely yellow. Coxae punctured, the posterior pair with a large black 

 mark on the outer side ; apices of the tarsi blackish, the hinder pair yellow. Areolet 

 higher than long, open at the apex, angled sharply on the lower side. 



11. Hemiteles sexlineatus. 



Pallide flavus ; antennis, lineis 6 thoracis, metanoti basi abdommisque segmentis basi, nigris ; scapo subfrus annu- 



loque antennarum, albis ; pedibus fulvis, coxis flavis ; alis hyalinis, stigmate testaceo. $ . 

 Long. 8 millim. ; terebra 1*5 millim. 



Sab. Mexico, Presidio (Forrer). 



Antennae, if anything, longer than the body, thickened towards the apex, covered 

 with microscopic pile. Eace punctured ; clypeus and the lower part of the face pro- 

 jecting ; tips of the mandibles black ; the space surrounding the ocelli black, the black 

 projecting as a narrow short line in front and joined to the black occiput by a narrow 

 black line. Mesonotum closely punctured, the scutellum impunctate ; pleurae very 

 finely striated, punctured. Metathorax very finely punctured, the transverse keel nearly 

 straight ; tubercles broadly dilated laterally, not projecting much. A line on the lower 

 half of the pronotum, the mesonotum at the sides all round, a broad line on the middle 

 lobe, a narrower one on each of the lateral lobes, the sutures, the base of the meta- 

 notum (except a small space at the spiracles), a narrow line going down from it on the 

 outer side of the spiracles, and a broader and shorter one in the centre (not joined to the 

 black base), black. Abdomen shining, impunctate ; a band at the apex of the petiole 

 in front of the postpetiole, a broad band at the base of the second segment (but not 

 reaching to the base), and the base of the succeeding segments more narrowly, black. 

 Hind coxae punctured ; hind tarsi yellowish, the tips black. Areolet wider than long, 

 sharply angled on the lower side. 



Easily known from the preceding species by the more prominent metathoracic 

 tubercles, by the immaculate pleurae, by the petiole having only a small black mark, 

 and by the immaculate coxae. 



C Abdomen white and honey-yellow, with one or more black bands. (Species 12 to 15.) 

 1. Metathorax without tubercles. (Species 12 and 13.)
