(6) The /Second Tertiary Einbiid. 



Pictet in 1854 described JEmbia antiqua from Baltic amber, 

 and this has remained the single fossil representative of the 

 family ; E. westwoodi Hagen, from copal, being properly of 

 the recent period 



An insect occurring at Florissant, having a strong general 

 resemblance to a Termite, proves upon careful examination to 

 disagree in important particulars with all Termitidae, and to 

 agree well with the Embiidse, to which it must be referred. 

 It has even the peculiar streaked appearance of the wings, so 

 characteristic of this family. 



Embia florissantensis sp. nov. 



Length 12-|- mni ; head about 2 mra ; prothorax about If ; ante- 

 rior wing ll mm long and 3f broad ; posterior wing just over 

 9 mm long, but as broad as the anterior ; shape of wings nor- 

 mal, with the usual longitudinal bands of color, giving rather 

 the appearance of a flower-petal with colored veins. The 

 head is narrow-oblong, considerably narrower than in E. ( Oli- 

 gotoma) michaeli, McLachlan ; prothorax unusually elongated, 

 shorter, but not very much smaller than the head ; the distinct 

 venation consists of two parallel veins, barely separated, run- 

 ning along the upper part of the wing for about three-quar- 

 ters its length, nearly parallel with the costa, but gradually 

 neaiing it apically, and apparently fusing at their ends ; and 

 of an oblique vein in the anal region. According to the inter- 

 pretation of Melander* the parallel veins represent the sub- 

 costa ; and the oblique vein the cubitus, with its lowermost 

 branch. The color bands, regarded as representing veins, 

 show the media + radius, giving off two large branches above, 

 essentially as in E. uriclii Saussure (this Trinidad species is 

 presumably named after Mr. Urich, the well-known naturalist 

 of that island; hence there is no reason for perpetuating the 

 erroneous form "u/irichi"), except that the branches are 

 given off much sooner, the first about 4J mm from base of wing, 

 the second a little more than 4 mm from apex. The two lower 

 color-bands, representing the third media and first cubitus, are 

 also well represented. These particulars are derived from the 

 anterior wing, but the hind wing is similar. 



Bab.— Florissant, Station 11 ( W. P. Cockerell, 1907). Also 

 two from Station 13 (S. A. Rohwer, 1907, W. P. Cockerell, 

 1906). Melander, in giving an account of the discovery of E. 

 texana, remarks that Sapindus and Eysenhardtia grew pro- 

 fusely in the locality where it was found. It is of interest to
