brownish ; antennre black, with the first or first two joints brown-red ; 

 thorax about a third broader than long ; front legs brown, posterior 

 pairs black, anterior tibia? armed with two short prominent teeth, 

 separated by two or more smaller teeth. The male has the anterior 

 tarsi extraordinarily developed, and often lighter in colour ; it is the

 in British collections. L. lf-2 mm. 



On Mentha aquatica, Cynoglossum officinale, Teucrium scorodonia, Linarln 

 vulgari's, Helianthemum vitlffare, &c. ; locally common; London district, rather

The M. distinctus of Waterhouse's and other British catalogues must 

 be referred to this species ; the true M. distinctus, Sturm, has not been 

 found in Britain; it appears to be very closely allied to M. oLscurus, 

 but differs in having the anterior margin of the forehead emarginate, 

 and in the fact that it has no cross reticulation between the punctures 

 of the upper side. 



M. ery thro pus, Gyll. (carinulatus, Forst.). A small species, variable 

 in size ; rather long oval, leaden black ; punctuation thick and fine ; 

 pubescence grey, fine and rather dense ; upper surface with distinct 

 cross reticulation between punctures; antennas brown-red, sometimes 

 rather dark, sometimes quite light ; thorax about a third broader than 

 long ; legs lighter or darker red or ferruginous, hinder pairs often pitchy, 

 anterior tibia? armed with two short prominent teeth separated by smaller 

 teeth ; male with a small transverse keel on the last abdominal segment ; 

 the species is closely allied to the preceding, but may be easily known 

 by its smaller and more oval form, emarginate forehead, lighter an- 

 tennae, and the male characters ; some specimens are very small. L. 

 1-1-| mm.
