Sphecapnta conica, teste Brauer, should have bare cheeks ; all 

 ours I believe have some bristle-like hairs on the cheeks, and, there- 

 fore, also teste Brauer, would work out to Arrhenopus piJiqena^ Rond. : 

 Mr. Verrall I know inclines to believe the names synonymous, and 

 that the presence or absence of the hairs is not of specific import- 

 ance. The species is the smallest of the lot and is paler and greyer 

 and unmistakeable at a glance : it seems specially associated with 

 Oxyhelus uniglumis, F. 



The two Miltofjrammas are very closelv allied ; but punctatum, 

 especially when looked at from in front always has distinct spots on 

 the hind margins of the segments, while germari, which has none, on 

 the other hand shows marked tessellations, or alternations of light 

 and dark reflections: germari too has distinctly yellow basal antennal 

 joints and in the male has simple fore tarsi, whereas, punctatum has 

 some strongly developed hook-like hairs which look like long claws, 

 and which probably serve instead of the true claws which are very 

 small. M. punctatum seems most common round the burrows of bees 

 of the genus Colletes. 



Setulia grisea {teste Brauer again) should have scattered hairs 

 on the cheeks; that is to say the genus {3Ietopodia, Brauer calls it), 

 is so characterised ; but I carefully examined all Mr. Ilamm's seven 

 specimens for these hairs and even under the microscope could only 

 think I saw a few ; my one specimen on the other hand shows a 

 number of distinct but pale down-like hairs, by no means answering 

 to the description '' scattered " ; moreover, none of the descriptions 

 published of grisea, Mg., mention the, as I think, characteristic, 

 abdominal markings, which, however, are certainly variable : the most 

 conspicuous feature is a dark central line which is broken up into a 

 pair of long spots on each segment, these spots not always reaching 

 the fore margin of the segments ; then there is usually another spot 

 on the hind margin of each segment at each side, and these are 

 occasionally lengthened nearly to the fore margins. The whole 

 insect is yellower in appearance than either of its allies, its frontal 

 streak not much yellower than the rest of the face. It is smaller on 

 the average than M. punctatum, but the largest specimens are as big 

 as ordinary sized punctatum ; of the eight I have examined the length 

 varies from 5 mm. to 7^ mm., thus somewhat exceeding the measure- 

 ments quoted by Schiner and others. In spite of the apparent 

 disagreements I have little doubt in my own mind that I have 

 correctly identified the species ; it should be readily recognised by
