AUSTBALIAN BEES IN THE QUEENSLAND MUSEUM.— COCKEKELL. 267 



Prosopis xanthopsyche n. sp. 

 Male. Length about 4-5 mm. ; black, with the face below antennae (the surface 

 •dull), bright chrome-yellow, including a quadrate supraclypeal mark ; lateral face- 

 marks broadly truncate above, but notched ; mandibles (except tips) and labrum 

 bright yellow ; face rather broad ; scape ordinary, with a yellow line in front ; 

 flagellum long, pale dull reddish beneath ; upper border of prothorax (not reaching 

 tubercles) and tubercles yellow ; mesothorax and scutellum dull, not evidently 

 punctured (the compound microscope shows minute well separated punctures on 

 a tessellated surface) ; metathorax rounded, distinctly glistening above, the extreme 

 base rugose and dull ; tegulse small and dark ; wings dusky hyaline, stigma dark 

 brown ; recurrent nervures joining first and second submarginal cells near ends ; 

 second submarginal narrowed above ; anterior knees, tibiae (except a large mark 

 behind) and tarsi, middle tibiae at base and apex, and hind tibiae broadly at base 

 all yellow ; middle basitarsi and basal half of hind ones yellowish-white ; abdomen 

 dullish, with a satiny lustre, venter simple. 



Brisbane, 24-9-18 {Hacker). The specific name is fanciful, given because 

 the yellow area of face, viewed upside down, has the outline of a moth with wings 

 directed backward. In my table this runs to 36, but is unlike any of the species 

 falling in that vicinity. 



Prosopis amatula n. sp. 



Male. Length about 3-5 mm., black, slender, with the face below antennae 

 and narrow upward extensions along orbits, the very short (heart-shaped) scape, 

 second antennal joint (short and transverse) and the tubercles very pale yellow ; 

 face rather broad, polished ; flagellum long, very pale yellowish-red beneath ; 

 labrum and mandibles entirely pale yellow ; mesothorax and scutellum shining, 

 but minutely sculptured all over ; area of metathorax broad, ill-defined, micro- 

 scopically cancellate ; wings hyaline, stigma sepia ; first recurrent nervure joining 

 first submarginal cell near end, second meeting outer intercubitus ; legs light yellow ; 

 hind femora black, yellow at base and apex ; hind tibiae with apical half dark ; 

 abdomen slender, claviform, second segment pale red apically. 



Caloundra, Q., 20-1-16 {H. Hacker). Runs to P. jyrimulijncta Ckll. in my table, 

 but is very distinct. It may also be compared with P. asinaUa Ckll., but that is 

 larger, with longer clypeus and supraclypeal area, &c. P. bacillaria Ckll. differs at 

 once by the slender scape and dull mesothorax. P. mdnuscula Ckll. is readily 

 distinguished by the scape and absence of yellow supraclypeal area. P. pnlchrijoes 

 Ckll. has a slender scape, larger (deeper) stigma, &c. Under the compound microscope 

 the second antennal joint of P. amatula appears circular, about as broad as long. 



Prosopis brevior Cockerell. 



Male. One from Caloundra, 20-1-16, taken with P. amatula. One Oxley, 

 Brisbane, 17-9-14 {Hacker).
