with light reflections on the sides of the hypostome ; forehead hav- 

 ing a black point ; antennae reddish-brown : thorax dark-brown 

 above, the colour disposed in three broad stripes : abdomen narrow 

 and cylindrical, the basal segment, as Avell as all the rest, ferrugi-

Likewise of frequent occurrence, at least in many parts of the 

 country. In Scotland we notice it every summer in the neighbour- 

 hood of Edinburgh and in Roxburghshire, and have seen specimens 

 from other southern counties. " London district." Stephens Calal.

 forehead with two brown stripes and a shining yellow triangular 

 mark on the crown ; antennae reddish-brown ; the third joint ap-

 Very dissimilar to any hitherto described, both on account of its 

 small size, obscure colours, and somewhat peculiar facies ; it appears 

 also to differ in some measure in its habits from the other species. 

 Black ; face yellow, with a silvery- white play of colour ; vertex 

 brown ; antenna? (which are rather long in proportion to the size 

 of the body) black, the second joint, and base of the third fulvous 

 on the inner side : upper lip elongated, tongue very long. Tho-
