 the same situations. It can be distinguished at once, however, by the 

 two-notched median carina, the Spharagemon having but one.

6. Trimerotropis longicornis, new species. (PI. I., figs. 1-4.) 



<£ . Of medium size, dull grayish-brown, paler beneath. Head of 

 average size, ash-gray below the ocellus, infuscated above. Face evenly 

 but rather sparsely and indistinctly punctate throughout. Occiput con- 

 siderably elevated above the pronotum, evenly convex, dark grayish- 

 brown. Scutellum a little longer than broad, strongly sulcate, limited in 

 front by a V-shaped depression. Median carina present, but faint. 

 Lateral carina well marked, forming a very obtuse and somewhat rounded 

 angle opposite the anterior margin of the eyes, from which they converge 

 to meet the frontal costa. Lateral foveolse triangular, rather large and 

 shallow. Frontal costa failing by some distance to reach the clypeus, 

 sulcate at and for a short distance below the ocellus, where it is slightly 

 expanded ; above the ocellus plane and evenly punctate. Lateral carina? 

 of the face reaching the clypeus, but not prominent. Eyes moderately 

 prominent, about as long as the genal groove. Antennas surpassing the 

 hind femora by about one-fourth the length of the latter. Pronotum 

 dark grayish-brown, rather short. Greatest width of disk about seven- 

 eighths of the length. Prozone somewhat elevated and tectiform, three- 

 fifths as long as the metazone. Disk of metazone much lighter than the
