18 Mr. T. D. A. Cockerell — Descriptions and 



tongues, while those of the females are broad and obtuse, as 

 in Prosopis. Thus the acute and obtuse-tongued bees are 

 united in a single genus ! Another noteworthy feature is a 

 comb on the first two joints of the maxillary palpi. The 

 females apparently eat pollen ; at least the tongues of Mero- 

 c/lossa parallela (Ckll.), M. penetrata percrassa (Ckll.), and 

 M. melanura (Ckll.) are full of it. According to Perkins, 

 Prosopis also eats pollen *. 



Hferoglossa eucalypti, sp. n. 



<J. — Length about 9 mm. 



Black and red, with very pale yellow markings; head 

 black, the cheeks obscurely reddish ; vertex rough and densely 

 punctured ; front with a median raised line and on each side 

 of it a broad smooth shining area, rounded and sharply defined 

 above ; clypeus very prominent, with a very broad deep 

 sulcus or excavation on each side, a deep trough running 

 down each side of the face ; face of clypeus shallowly trans- 

 versely concave ; face below antennse pale yellow, except the 

 supraclypeal area and the inner, almost hidden, part of the 

 lateral sulci ; lateral marks extending upward as broad bands 

 nearly to level of top of smooth frontal areas, and ending 

 very obtusely ; labrum and mandibles ferruginous ; yellow 

 colour extending across malar space and as a band halfway 

 up posterior orbital margins; scape swollen, sausage-shaped, 

 bright ferruginous ; flagellum ferruginous, infuscated above, 

 except the last joint ; thorax strongly and quite closely 

 punctured, black, with most of the protliorax, and the meso- 

 thorax except some blackish suffusion posteriorly (extending 

 about to middle sublaterally), ferruginous; tubercles, small 

 subquadrate spot behind, axillae, and two large but widely 

 separated spots on scutellum all cream-colour ; area of meta- 

 thorax triangular, rough and longitudinally strigose, con- 

 trasting with the adjacent sides of metathorax, which are 

 covered with greyish-white hair; tegulae dark reddish fuscous, 

 with a cream-coloured spot. Wings clear, nervures dark 

 fuscous, stigma ferruginous, with a dark margin ; first r. n. 

 joining first t.-c. Legs dark reddish, with glittering hairs, 

 small joints of tarsi becoming clear ferruginous ; anterior and 

 middle femora short and thick. Abdomen well punctured, 

 chestnut-red and fuscous, the first segment fuscous, base and 

 apex of second and third suffusedly fuscous ; apex broad, 



* Another pollen-eater is Pseudomasaris vespoides (Cresson), as was 

 observed by my wile at Pecos, New Mexico. The pollen eaten is that of 

 Pentstemon.
