 in A. MJw/onH'is, pubescence yellowish. Abdomen elongate, margins of segments 

 narrowly testaceous, apex testaceous, coarsely punctiired, pubescence yellowish. 

 Legs reddish-testaceous. Length, 4'3 mm. 



Compared with A. uniformis, Duv., which is the ouly European 

 specdes with which it could lie confused, its stouter buikl, shorter and 

 broader head and thorax, and stouter antennae, distinguish it . 



Taken at Ta Baldu in veo-etable (h'hris in November, HM)1. 



Type in my collection. 



The insect recorded by me fi-om Malta as Siinins uniformis, on 

 Mr. Walker's authority (named by M. Fauvel), proves to be referable 

 to the same species. A. gattoi is the Suuius, n. sj)., of my List.*

 delited during my visits to Malta.
