Central American species recorded by Dr. Sharp in the " Biologia," in 

 1885, under the name B. ohsoldvs Say (=iohtectns Sa,y , 2)oJl id i2)es Fahr., 

 and fabae Riley), agreeing with it in having a conical laterally 

 unarmed prothorax, a red [apical joint to the antennae, and a yellow-red 

 roughly sculptured pygidium. B. jjusillus Germ. var. seminarius 

 Baudi (det. Schilsky), from the Mediterranean region, has a smoother 

 black pygidium, unicolorous dark apical joints to the antennae, &c. 

 Say's names were published in 1831, those of Fahraeus in 1839. The 

 three specimens representing B. lentis Boh., from Gravesend and Birch 

 Wood, in the Power collection at the British Museum, have the sides 

 of the thorax toothed, and agree perfectly with typical examples of 

 that species. It has been recorded as bred from imported Egyptian seeds 

 by the Rev. W. W. Fowler, to whom I am indebted for specimens. A 

 third species, B. cMnensis L. ( (^ 'pectinicortiisJj.), has also been found in 

 imported lentils, and recently captured examples of it have just been 

 given me by Mr. W. West. This last-named insect (which may be 

 distinguished by the pectinate ( c? ) or serrate (?) antennae, and by 

 having the under- side of the hind femora grooved and bearing two 

 teeth, of which that on the inner-side is the larger) has been found at 

 large by Mr. West and other collectors at Dartford or Darenth Wood, 

 by Mr. E. A. Waterhouse at Putney, and by Dr. Sharp in the New 

 Forest. Commander Walker has met with it in various localities in 

 China. The type of B. irresectus Fahr. was from Persia. — G. C. C.]. 



NOTE ON AN ANTHOMYID FLY, PHAONIA (HYETODESIA) 



TRIMACULATA Bouche, NEW TO THE BRITISH LIST. 



BT J. T. WADSWOBTH, 



In June, 1914, whilst collecting larvae and pupae of the " cabbage- 

 root fly, " Chortojjhila hrassicae, at the roots of cabbages, I obtained a 

 few larvae that were larger than those of this species. They differed 

 also from the latter in possessing a smooth rounded posterior segment, 

 whereas the last segment of the " cabbage- root " maggot is obliquely 

 truncated, and possesses seven pairs of pointed tubercles, in addition 

 to the projecting pair of posterior stigmata which are common to both 

 types of larva. 



The larvae pupated in early July, and adults emerged in fifteen 

 to twenty-one days from the date of pupation. The actual dates of 

 emergence of three specimens were July 20th, 23rd, and 24th.
