278 HYMENOPTERA ACULEATA. 



gate, with long antennse, and the ? short, with short an- 

 tennae ; the tongue is very elongate, the lora are elongate, 

 and very strongly developed, labial palpi four-jointed, the 

 three lower joints sheath-like, fourth divergent, cylindrical, 

 paraglossEe ensheathing the base of the tongue, produced 

 into two elongate subfiliform processes, slightly widened 

 and truncate at the apices, maxillary palpi six-jointed ; wings 

 with two submarginal cells ; $ with the seventh ventral 

 segment hidden, produced laterally into a long process, the 

 eighth very narrow and long, widened and spoon-shaped 

 at the apex, which is just visible beyond the sixth ; 

 posterior tibiae with a basal patella. Although the labial 

 palpi in this genus are certainly formed like those of the 

 Ajtiiie., every other character it possesses associates it 

 rather with this family, so that I have no doubt that it 

 is right to place it here. 



B,. quinquespinosus, ^inn. — % black, head and thorax 

 clothed with short brown hairs, very finely and closely 

 punctured, tegulaa piceous, wings subhyaline, darker at the 

 apex, with only two submarginal cells, propodeum dull, 

 radiately striate at the base, closely punctured posteriorly ; 

 abdomen dull, closely, finely, and evenly punctured, clothed 

 with very short hairs, apex of each segment narrowly 

 piceous, with a band of pale, ochreous, decumbent hairs, 

 that of the basal segment interrupted, that of the fifth and 

 sixth segments golden, fifth segment without a central rima, 

 sixth with the pygidial area triangular, its margins narrowly 

 raised, beneath punctured, apical margins of the segments 

 pale, and clothed with pale hairs ; legs clothed with golden 

 hairs, intermediate calcaria very long, pale, and serrate in- 

 wardly, apical joints of the tarsi testaceous. 

 L, 9 mm. 



The $ has not yet occurred in this country, but it may 

 be readily known by its pale antennae, and the spiues of its 

 sixth ventral segment.
