442 Mr. F. Smith oti the Genus Eulema. 



This species varies not only in colouring but also in size. 

 The three apical segments are usually covered with femiginous 

 pubescence ; but specimens from Rio and others from Chontales 

 have the segments clothed with pale yellowish white. In 

 size it varies from 14 to 9 lines in both sexes. 



This insect is figured in Madame Merian's ' Insects of 

 Surinam,' plate 48. 



2. Eulema cajennensis.

I have seen the type of the species named '•'■fasciaia " by 

 St.-Fargeau ; the male is a rather worn specimen : that 

 described as '•'' cajennensis''' is certainly the same species in 

 good condition. 



3. Eadema ehgans. 



Evlema elegans, St.-Farg. Hym, ii, p. 13, 5 • 



Hob. Cayenne ; Santarem ; Chontales. 



I have examined St.-Fargeau's type specimen of this 

 species, and have seen examples from the above localities. 

 The male has the face of a metallic green, with more or less 

 of a coppery tinge ; the thorax, anteriorly, has also a metallic 

 lustre, as well as the tegulaj ; the posterior tibia? are convex. 

 The species is closely allied to E. cajennensis. 



4. Eulema terminata. 



Male. Length 13 lines. Head and thorax black, the abdo- 

 men obscurely asneous ; the pubescence black, excepting that 

 on the fifth and sixth segments of the abdomen, which is 

 pale fulvous ; the apical segment pale testaceous ; the wings 

 dark fuscous from the tegula to the base of the marginal cell, 

 beyond which they are pale flavo-hyaline ; the posterior tibise 

 with the longitudinal excavation above terminating in an 

 acute spine on each side at its apex. The spines are more 

 acute than in the male of E. dimidiata.
