ESMELINA. 



Mr. Pascoe's reference of this genus to the Leptopsides seems to 

 me very much open to criticism. The absence of ocular lobes 

 from the prothorax (not referred to by Mr. Pascoe in his diagnosis) 

 is much more suggestive of the Br achy derides, nor are the eyes 

 (although certainly a little more acuminated beneath than those 

 of most Br achy derides J very much different from those of some 

 species of Prypnides whose place among the Brachyderides is not 

 questioned. Mr. Pascoe calls the posterior corbulse "apertse," 

 but it seems to me they are rather of the form which M. Lacor- 

 daire calls " subcavemosse." I should incline to refer the genus 

 to the Brachyderides, where it seems to me to stand at no great 

 distance from Dermatodes, and in some respects to be very near 

 Mr, Pascoe's genus Styreus. I may say that I have examined 

 specimens of E. flavo-vittata, Pasc, in the Macleay Museum, said 

 to be named on Mr. Pascoe's authority, and have myself taken the 

 same species in the Blue Mountains (the original locality), and as 

 it is an insect with very characteristic and unusual markings on 

 the elytra I do not think there is any possibility of my identifica- 

 tion of it being erroneous. 



In describing the following new species of Esmelina I draw 

 attention to the probability that it may be Lagostomus australis, 

 Boisd., (^Za^og^omw* was a nom-prseocc, for which Dermatodes was 

 substituted). This is little more than a guess, founded on proba- 

 bility arising from the habitat of my insect and its resemblance 

 to Dermatodes. Dr. Boisduval's description consists of eight
