of Becker's figures. The frontal colouring varies a little; 

 when a specimen is in first-rate condition the i-raargins 



and the three spots on ihem are very distinct, the triangle is 

 narrowly bordered with grey,and there are a tew tiny parallel 

 n-v lines running from this to the front. A slight decree of 

 damage seems to remove the pollen easily, and then one can 

 only just glimpse the dark spots, the borders becoming faint. 

 In two worn specimens it is practically impossible to see the 

 frontal pattern. The length of the triangle also varies a 

 little, depending on the amount of shrinkage of the orange 

 lunule. In all main characters the agreement is good.

Siphunculina fntonsa, sp. n. 



Two rather indifferent .specimens occur of a species which 

 does not agree with any hitherto described. The general 

 colour is entirely black, but the head and thorax are provided 

 with peculiar hairs in regular rows on the thorax ; these are' 

 bright silky yellow, short and stout, like stubble. 



Head (top view) : — Frons slightly shining and very 

 minutely roughene 1, covere I with the ab >ve-described hairs; 

 triangle duller and also roughened, with its base about £ of

the vertical breadth, straight sides, and the point halfway 

 from vertex to antennae ; ocelli somewhat widely separated ; 

 no spots or marks on the head. In front the antennas are 

 deeply sunk in pits and approximate at the base, 3rd joint 

 orange with darkened tip, and a fine, bare, very short arista. 

 The palpi are hidden in the gum used to secure the specimens, 

 but appeal to be orange; tongue rather long. Side-view: 

 all shining black, very similar to Becker (I. pi. iii. p. 53).
