orbits, collar, band or two spots on scutellum, short line on postscutellum, two

 smooth and shining, very finely punctured; mandibles, antennae beneath and 

 legs ferruginous; second and third joints of flagellum short, about equal in 

 length; scutellum bilobate; wings hyaline, fuscous at extreme tip; a fuscous 

 spot or line on posterior tibise behind; abdomen shining; a band near apex of 

 first and second segments narrowed in the middle, a transverse spot on each 

 side of third and fourth segments and a band on the fifth, yellow; venter with 

 a broad yellow band on third segment. Length .30 inch. 



%. — Marked like the J except that the clypeus, spot above, and labrum, 

 are yellow; posterior legs behind and broad line on their tibise in front black, 

 knees, line on all the tibise in front, base and apex of posterior pair, and base 

 of their tarsi yellow. Length ..30 inch. 



Hob. — Porto Rico, (Mr. Leopold Krug). Four specimens. Re- 

 serubles ciibensis somewhat in ornamentation. 



Xoinada limata.— J .— Black or brown, and shining, clothed with short 

 pale pubescence, longer and more dense on sides of abdomen; a line on an- 

 terior orbits curved inwardly to clypeus, a dot on clypeus, collar, tubercles, a 

 dot on pleura, a bilunate line on scutellum, and the postscutellum, white; 

 antennse brown, ferruginous at base, third joint a little longer than fourth; 

 mesothorax smooth, polished, impunctured ; scutellum flat; pleura rather 

 coarsely punctured; metathorax with whitish pubescence at sides; tegulse 

 ferruginous; wings subhyaline, costal margin broadly fuliginous ; legs brown 

 or black, immaculate; abdomen finely punctured, clothed above with a short 

 sericeous pile, base tinged with ferruginous, a narrow continuous whitish band 

 on segments one, two, and four, and a broader interrupted one on fifth segment; 

 venter immaculate. Length .35 inch. 



Hab — Mexico, (Sumichrast). One specimen. This resembles very 

 closely the tibialis Cress., from Cuba, but in that species the legs are 

 red and the wings are dusky only at tip; in both species the meso- 

 thorax is polished and impunctured. 



Noniada mexicana.— 9 .— Black, opaque, head and thorax strongly 

 and confluently punctured; narrow anterior orbits ending in small spot on 

 each side of clypeus, narrow posterior orbits, spot on middle of clypeus, spot 

 on base of mandibles, collar, band at base of scutellum, one on postscutellum. 

 spot on each side of metathorax, and three snots on pleura, whitish; base 

 of antennse, tubercles, tegulse and legs ferruginous; third and fourth joints 

 of antennse about equal in length; scutellum obliquely flattened, roughly 

 sculptured; wings hyaline, costal margin fuliginous; abdomen slightly fer- 

 ruginous at extreme base, a narrow whitish band on first and second seg- 

 ments, curved anteriorly on the lateral margin, fourth and fifth segments 

 each with an narrow ill-defined pale band abbreviated laterally; venter with 

 a pale spot on disk of first segment and a broad band on second segment. 

 Length .35 inch. 



Hab. — Mexico, (Sumichrast). One specimen. Marked much like 

 limata, but more slender in form and separated at once from that 

 species by the coarsely sculptured mesothorax.
