390 SPOLIA ZEYLANICA. 
There is nothing in Schiner’s generic description of Phortica 
to prevent this species being included therein. Williston’s 
figs. (“ North American Diptera,” fig. 118, 1 and 2) show a 
much greater marginal convergence of veins 3 and 4 
than in the species now described, but his note on page 301 of 
the same work shows that there are species included in the 
genus with the first posterior cell wide open. (Schiner says 
“thence parallel to each other to the wing margin.”) As 
regards the dilated front tarsi of Ph. scutellaris referred to by 
Williston (td. loc. cit.), this would appear to be contrary to a 
generic character, which states “legs simple.” The genus 
will probably have to be divided up when overhauled by a 
specialist. 
The species described above is almost certainly that referred 
to by Rutherford (Trop. Agric., XLII., p. 220), but his 
specimens are not to be found. When he wrote, the habits 
of the insect were in doubt, but recently Mr. F. P. Jepson 
(Entomologist in charge of Shot-hole Borer Investigations) 
informs me (in litt.) that he has seen the larva eat a pupa of 
the beetle, tunnelling completely inside, and sucking it dry in 
about 20 minutes. The specific name suggested is proposed, 
therefore, on account of this. 
Trypetide. 
RIoxA MAGNIFICA n. sp. (Pl. I., Fig. 2). 
Female-——Head: Frons yellow, a brown median stripe, 
expanding indefinitely below lower superior orbital. Face 
yellow. Parafacialia with silvery pubescence, epistomal
