6. Black, somewhat shining; head impunctate, face silvery; nar- 

 row posterior orbits, broad anterior orbits, face, clypeus, labrum, dot 

 on base of mandibles, scape beneath, spot on each side of prothorax, 

 its posterior margin, dot on scutellum, transverse spot on postscutel- 

 lum, and extreme posterior angles of metathorax, white, the latter 

 silvery sericeous; anterior margin of clypeus broadly arcuate; apical 

 joints of palpi reddish; mesothorax with large, deep, scattered punc- 

 tures; metathorax broadly excavated down tbe middle; pleura and 

 coxae silvery sericeous ; tegulse piceous; wings hyaline, apex slightly 

 dusky; legs fulvo -ferruginous, posterior pair very long, their tarsi 

 dusky at tips; coxje and trochanters black, the four anterior coxae in 

 front, tips of posterior pair, spot at apex of four anterior femora, 

 anterior tibise in front, and basal joint of four anterior tarsi, white; 

 abdomen black, shining, a large spot on each side of first segment at 

 tip, slightly notched behind, and a fascia at tip of remaining segments, 

 dilated laterally, and more or less deeply notched on each side an- 

 teriorly, white ; the fascia on two apical segments interrupted on each 

 side, dividing each into three spots, the middle one the larger; venter 

 immaculate. Length three and one half to four lines. 



Hab. — Orizaba. (Prof. Sumichrast. Coll. Am. Ent. Soc.) Two 

 ? specimens. 



3. Ceropales femoralis, n. sp. 



?. Black, shining; face, pleura, metathorax and coxae, more or 

 less silvery sericeous; face short; clypeus transverse, anterior margin 

 arcuate; narrow posterior orbits, anterior orbits broad above an- 

 tennae, spots on each side of clypeus, and scape beneath, white; 

 thoi-ax sculptured and ornamented as in albopicta, except that the 

 metathorax is more depressed behind; wings hyaline, dusky at tips; 

 second and third submarginal cells shorter than usual, being nearly 

 quadrate inform; legs subrobust, black; spot on anterior coxae in 

 front, spot on tip of two .posterior pairs, and spot on tip of four 

 anterior femora, white ; anterior legs in front, stain on middle femora 

 above, base of their tarsi, and posterior femora except extreme base, 

 ferruginous; abdomen smooth, convex, silvery sericeous in certain 

 lights; each segment with a lateral, apical, transverse, sublunate, 

 white mark. Length three lines. 



i/aZ*.— Orizaba. (Prof F. Sumichrast. Coll. Am. Ent. Soc.) One 

 specimen. In this, the second and third submarginal cells are shorter 

 than in the two preceding species, and each receives a recun-ent ner- 

 vure in the middle; whereas in the other two the r-ecurrent nervures 

 are more approximate.
