No. 3.] PATTON ON CERTAIN BEES. 475 



ANTHOPHOE^. 



Paraglossse shorter than the first joint of the labial palpi, lanceolate, 

 not pubescent; maxillary palpi with the basal joint free from the max- 

 illa, in a line with the second joint and not incrassate. Labrum with a 

 deflexed and thickened margin [Habropoda excepted), the margin not 

 notched. Antennae of the male not elongated {Rahropoda excepted). 

 Submarginal cells three. 



The European genera Saropoda Latr., with five-jointed maxillary palpi 

 according to Latreille, or with four -jointed maxillary paljii according to 

 Smith, and Melliturga Latr., with six jointed maxillary pali)i, differ from 

 the genera here treated in having the third joint of the labial palpi con- 

 tinuous with the second joint. In the other genera the maxillary palpi 

 are six-jointed. 



A. Ocelli in a line or curve ; clypeus of the male not colored. Max- 

 illary x)alpi flattened ; basal joints of labial palpi not wing-margined. 

 Pubescence of legs conspicuously plumose. Stigma present; marginal 

 cell lanceolate; third submarginal cell longer than broad and much 

 narrowed towards the marginal ; origin of the first recurrent nervure 

 beyond the origin of the cubital nervure. Pubescence of the wings 

 continuous; limb of the wing not traversed by distinct lines free of 

 punctures representing the continuation of the cubital and externo- 

 medial nervures. Basal lobe of the posterior wings extending beyond 

 the middle {Emphor) or to the apex of the submedial cell.

Type: B. enavata, 



$, Head small, narrower than the thorax; clypeus little elevated; 

 ocelli in a line; labrum with its anterior border slightly angular, ele- 

 vated and forming a slight tooth in the middle, the edge deflexed. Man- 

 dibles arising close to the eyes, unarmed. Probofcis not elongate. 

 Maxillary palpi somewhat flattened, joints two and three each nearly 

 twice as long as the first joint, the apical joints diminishing in length. 

 Labial palpi with the first joint longer than the second. Enclosure at 

 the base of the posterior tibiiC well marked; the legs with long and 

 dense pubescence forming the scopa; tarsal claws swollen. Anterior 

 wings with the stigma of moderate size; the marginal cell lanceolate, 

 the tip pointed but not appendiculate ; second submarginal cell quad- 

 rate, receiving the first recurrent nervure near the apex ; third submar- 

 ginal cell much narrowed towards the marginal ; limb of tlie wing mod- 

 erately punctured ; externo-medial nervure abruptly bent just beyond 

 the origin of the first recurrent nervure ; anal lobe of the posterior wings 

 equalling the submedial cell in length. The lateral impressed lines of 

 the abdominal segments indistinct; area on the sixth segment narrow; 

 venter with long and dense pubescence. 



^ , Antenna little longer than in the female. Labrum with the de-
