Fabricius and those writers who have followed him in uniting 

 M, socia with Lithosia, have been misled by analogy : the 

 singular terminal joint of the labial palpi of that insect would 

 have induced us to make a separate genus of it, had we not 

 the strongest aversion to multiply names except where it is un- 

 avoidable ; we have therefore made it the type of a genus which 

 will connect Galleria with Chilo, a group separated from 

 Crambus ; for it appears that M. socia is nearly related to 

 both, and M. jiammea is a Chilo in habit, but it wants their 

 elongated palpi. 



The antennae and legs of the following species agree per- 

 fectly, but other differences render it advisable to form them 

 into three divisions. 



A. Labial palpi with the terminal joint the longest. The 

 superior wings obtuse. 



1. M. socia Tab. — Ha'w. — sociella Fah. — Tribunella Hilh. 

 Middle of July in and near gardens round London, in 



Norfolk, Yorkshire, Perthshire, &c. 



2. M. bipunctana Ha*w. MSS. — sociella Hub. TinicJB, pi. 4. 



/24. 

 Taken by Mr. Hatchett at the Jews' Burying Ground, 

 Stepney. It is necessary to observe that I have not had an 

 opportunity of examining this species. 



B. Labial palpi with the second joint the longest. 

 * Superior wings obtuse. 



3. M. sericea Nob. This insect has a silky appearance. The 



thorax and superior wings are dull ochreous with a 

 carneous tinge, minutely freckled with fuscous, and 

 a row of dots at the posterior margin of the same 

 colour; the body is paler, and the inferior wings 

 almost white ; it is not so large as M. jiammea. I 

 once took a specimen in a garden in Suffolk, flying 

 late at night, die end of June ; and Mr. Dale took a 

 moth the 29th of June at Whittlesea Mere, which 

 I think is the same species. 

 ** Superior wings lanceolate, somewhat acute. 



4. M. flammea Nob. 



The only specimen I have seen of this insect, was purchased 

 of a collector by Mr. Dale. It is understood to have been 

 taken at Lewisham near London. 



The plant is Sisymbrium Nasturtium (Water Cress).
