342 ON THE COLEOPTERA OF ST. TI>'CEST. [Apr. 19, 



H. Smith from Grenada. They are very Uke S. thoracicus,- but are 

 smaller on the average when a series like ours of about 35 examples 

 is examined. They are, moreover, rather more oblong and more 

 convex, and have a third of the elytra red at the apex, and this 

 red part often more brightly coloured than in S. thoracirus. In 

 some examples the thorax has a black spot on the base, as is more 

 usual in S. thoracicus ; but if we are right in our reference no 

 reliance can be placed on the presence or absence of this mark, 

 as the great majority of specimens of both species which I have 

 seen are free from it. ^

There are about eighteen examples of a Scymnus among those 

 sent from Grenada, which agree in many of their details with 

 Mulsant's description, and as MM. Elentiaux and Salle referred 

 without hesitation a species from Guadeloupe to S. roseicollis, 

 I do not venture to give our insect a new name. Our insect is 

 oval, pointed towards the apex ; the head, thorax, and two round 

 spots detached from the apex are bright yellow ; the body is 

 blackish, only yellow towards the tip of the abdomen. The 

 example in Crotch's collection is from Guadeloupe, but is not 

 S. roseicollis Muls. in my opinion, and has no typical value.

This species is near to the one described by me as Scymnus 

 hogei (Biol. C.-Am., Col. vii. p. 230). It is smaller, more convex, 

 and the red vitta of the elytra is of a different form, not being 

 shaped like a comma, but of even width throughout. The head is 

 obscurely red, the thorax is rather narrow and blackish, except 

 near the front angles. The body is blackish ; the punctation is 

 not visible under a Coddington lens. The single example from 

 Balthazar is the type ; the specimen from Mount Gay is a Uttle 

 lighter in tone, the apex of the elj'tra and that of the body 

 being distinctly red, but I think it obviously represents the same 

 species. I cannot pretend to give fm'ther details, as the specimens
