margin a reflexed appearance, front and vertex more coarsely pimctured tlian the 

 clypeus ; beliind the insertion of each antenna, there is a strong depression which 

 terminates angu'arly above ; just above these depressions the face is slightly pro- 

 tuberant ; front rather strongly furrowed medially, the furrow interrupted by the 

 fore ocellus, then extending back on the occiput dividing in its course the swollen 

 portion between the ocellus into two strong lobes or tubercles ; space between the 

 eyes at the vertex about equal to the length of the first two joints of the antenna; 

 united ; dorsulum depressed in the middle, anteriorly its punctuation sparser than 

 that of the front ; scutellum punctured likewise, not impressed ; upper surface 

 coarsely rugose or nigged, the metalpleura: strongly and obliquely striated, the pos- 

 terior face coarsely gianulated, with a strong depression at base and with a strong, 

 sinuous, transverse ridge at the top ; four hind tibiae and tarsi tolerably well armed 

 with whitish spines ; abdomen with exceedingly fine punctures, strongest on the 

 second ventral segment ; pygidium with a few scattered punctures, acute at lip, 

 convex. Black, last dorsal segment red ; front, face and clypeus with silvery 

 pubescence ; vertex and thorax more cr less with short, fuscous pubescence ; abdo- 

 men with sparse silvery pile ; wings subhyaline, palest basally, iridescent ; margi- 

 nal cell obtuse at apex. Length, 9 mm. 



(j . — Differs from the y by the clypeus being not emarginate ; the stronger 

 punctuation of front and vertex ; the shorter antenmv ; the slightly impressed 

 scutellum and more finely sculptured metathorax. Length 7 mm. 



Southern Florida [Robertson). To the genus Tac/iysf/icx 

 belong several of our species of Larra, prominent among them are 

 tenni/iata, acuta and tarsata. T. apicalis is related to the two first 

 mentioned species but is at once distinguished by the sculpture of 

 metathorax.

9. — .interior margin of clypjus strongly rounded out ; front convex, the face 

 in the region of insertion of antenna; depressed, third joint of antenna very little, 

 if anything, longer than the fourth space between the hind ocelli but little less than 

 the distance between them and the nearest eye-margin ; posterior margin of pro- 

 thorax subangular ; metathorax rather short, not impressed, but with a slight pit or 

 fovea at the extreme base in the middle, four hind tibins strongly armed, especially 

 the hind pair, which are serrate ; longer spur of hind tibia; more than one-third as 

 long as the first joint of the hind tarsi : claws with a large tooth on inner margin ; 

 abdomen fusiform polished, the apex rather densely clothed with long, brownish 

 hairs. Black, the head and thorax with a slight, greenish tinge ; face, clypeits, sides 

 of thorax and coxa' with silvery pile ; wings subhyaline, their apical margins fuscous ■ 

 second submarginal cell more than one-third wider beneath than at the top, its 

 height is about equal to its width at tlie top ; first recurrent nervure received by 

 second submarginal cell, before the middle, the second is received by the third sub- 

 marginal in about the middle, the marginal cell does not extend to the apex of the 

 third submarginal. Length 7 mm.
