HABROPODA MISERABILTS. 



Antliophora misei-aUlis Cress., Proc. Acad. Nat. Sci. Phila. 1878, p. 191. 



To the genus Sahropoda belong also (to judge from such characters 

 as are given in the specific descriptions) Pluto Dours, aurulentocaudata 

 Dours, melanopyrrha Dours, mucida Cress., and Morrisoni Cress. 



Anthophora Latr. 



Type of Westwood : A. retusa (Linn.). 



Labrum with a transverse and narrowly deflexed or thickened anterior 

 margin ; the sides of the labrum curved downward, the axes of the 

 curves parallel and giving to the upper face a quadrate form. Man- 

 dibles simple or bidentate at the apex. Maxillary palpi with the second 

 joint two or three times as long as the basal joint, the following joints 

 ]nuch shorter and successively decreasing in length, the sixth joint 

 slender and pointed. Antennce of the male reaching to the teguhie. 

 ]Marginal cell extending beyond the third submarginal no more than the 

 length of the latter, obliquely appendiculate at the apex. Second sub- 

 marginal cell pentagonal, pointed at the base, the recurrent nervure 

 received near the middle; third submarginal cell not narrowed towards 

 tlie marginal. Enclosure at the base of the posterior tibiae in the female 

 large and rounded. Disk of last abdominal segment variable, but not 

 broad as in Eabrojjoda. 



ClISODON n. g. {/.hiq -{- oow'^). 



Type : Clisodon tcrminalis. 



Anthoplwra terminalis Cress. , Trans. Am. Ent. Soc. ii, p. 292. 



Mandibles in both sexes tridentate, the tip having a tooth beneath as 

 well as above, the central tooth the longest. Area at the base of the 

 posterior tibiee of the female shari)ly defined and its tip narrowed and 

 elongate. Otherwise as in Anthophora. The disk of the sixth abdominal 

 segment has a narrow smooth area in the female ; in the male the apical 

 segment is furcate or terminates in two flattened lobes, and there is no 

 distinct area at the base of the posterior tibiae. The fiftli and sixth joints 

 of the maxillary palpi are equal in length in the male, but in the female 

 the sixth joint is only one-half as long as the fifth. The second trans- 

 verse submedial nervure forms a continuous curve with the bent portion 

 of the externo-medial nervure. 



AntJiophora furcata (Panz.) closely resembles terminalis and may be 

 related, but the mandibles have been described as bideiitate.
