370 Mr. Westwoop on Embia, a Genus of Insects 
portion of this work, no characters were given of the insects figured in it. In 
the Familles Naturelles du Régne Animal, 1825, we however find a second genus 
introduced into the family Termitine by Latreille, under the name of Embia, 
with the short observation, “ Voisin du précédent (Termes) mais à antennes 
différentes*.” In the 2nd edition of the Règne Animal4- this second genus is 
referred to Savigny's insect, with the observation, “ Des insectes des contrées - 
méridionales de l'Europe et d'Afrique, analogues aux Termes; mais à tête 
plus large que le corselet, à tarses de trois articles, à ailes ne dépassant guére 
l'abdomen, ou nulles, ayant les pieds comprimés, les deux jambes antérieures 
plus larges, sans yeux lisses, et dont le corselet est alongé, forment le genre 
que j'ai indique sous le nom d’Embie (Embia) ; il est figuré dans le grand 
ouvrage sur l'Egypte." i 
I know not upon what authority Latreille here indicated Europe as the 
locality of this insect; it will be seen, however, that other species of the genus 
inhabit both Asia and South America: neither can I decide from what ma- 
terials he was led to state that they are sometimes wingless, as in Savigny’s 
figures they are represented with wings; from analogy, however, they may be 
fairly considered as occurring without these organs in those states in which 
the Termites are destitute of them. Moreover, in Savigny’s figures and in 
the other species the head is neither larger nor broader than the thorax, and 
the posterior femora are as large as the anterior. No further account has 
been published of this genus; the subsequent description is consequently 
entirely drawn up from Savigny’s figures, the accuracy of which no one will 
venture to doubt, and which I have added to my plate. Of the second species, 
a magnified figure was published in Mr. Griffith’s English translation of the 
Règne Animal under the name of “ Embius ? brasiliensis, G. R. Gray,” with 
the observation, “We insert a figure of a singular insect, which bears some 
similarity to the genus Embia, but differs in having the antenne as long as the 
body, the thorax much longer and more separate from the head, which is 
rounded posteriorly, the terminal joints of the palpi rather larger; it therefore 
may be formed into a distinct subgenus, which Mr. Gray has named Olyntha. 
The species is from South America, therefore is named brasiliensis.” Unfor- 
tunately no indication of the natural size of this insect was given; and the
