that the two insects of which V. Audouin speaks belong to one and the 

 same species ; fig. 9 represents the insect from above, fig. 10 from below. 



Mr. R. Gray, in Grifiith's ed. of Cuvier, vol. xv (Insects, vol. ii., 1832) 

 p. 346, translates Latreille's note and describes briefly a new species from 

 Brazil as a new genus, Olyntha Brazil'misis. It was separated from 

 Embia by having the antennae as long as the body, the thorax much longer 

 and more separate from the head, which is rounded posteriorly, the ter- 

 minal joints of the palpi rather longer. It is figured (magnified) on pi. 

 72, f. 2, by Westwood, and named on the plate Embius ? Braziliensis, 

 J. R. Gray. The type formerly in Mr. Children's collection is now in the 

 Brit. Museum. 



Prof. J. O. Westwood in Trans. Linn. Soc. Lond. 1837, ^o^- ^vii., p. 

 369-374, pi. I (read March 4th, 1834) published : Characters of Embia, 

 a genus of insects allied to the white ants (Termites), with description of 

 the species of which it is composed. He describes three species which 

 he places as three sub-genera of the genus Embia, after single specimens, 

 one of them, Embia Savigtiyi West., only after Savigny's figures. The 

 second, Oligotoina Saundcrsii Westw., from Bengal (the type now in the 

 Brit. Museum) ; the third, Olyntha Braziliensis Gray, formerly described 

 in Griffith. The sub-genera are divided in such with 5-jointed palpi, 

 antennae shorter than the prothorax, with less than 20 joints (Embia and 

 Oligotoma), and with 4-jointed palpi, the antennae about as long as the 

 body ; the 4th vein trifid (Olyntha). The first group was divided by the 

 4th vein trifid (Embia) or bifid (Oligotoma). The numerous details 

 figured give to his work a permanent value. The genus Embia is said to 

 combine Termes with Eusthenia, a Perlid ; why is not stated. 



Burmeister, 1839, ^" ^^^^ Handb., vol. ii., p. 768, elevates his four 

 species to a family of equal value with the Termitina, and brings the 

 Embidae to his Tribus Corrodentia. He describes four species, one new, 

 O. rnficapilla. But his O. Braziliejisis is not Gray's species, and belongs 

 to O. Batesi McLachl. He corrects the number of the joints of the 

 maxillary palpi by Westwood for Olyntha, which has indeed five joints, as 

 the others. Burmeister elevates the three sub-genera of Westwood into 

 genera. 



Rambur, 1842, Neuropt. p. 310, places the Embides as a family near 

 the Termites. His general characters are excellent ; only four species are 

 described, and very well. Three of them are believed to be new, but his 

 E7nb. Latreillii is 0. Saundersii, and his E. Klugii probably O. ritfi-
