EMBIIDINEN 53 



alike, shorter; tarsus witli first point shorter th,m tibia, heut to below dilated with a median furrow : no spine: 

 the two apical joints small, much shorter; middle legs similar bul shorter, thinner, very little dilated; hind 

 legs a stout as the forelegs, femur rauch dilated, tibiae shorter, not dilated; tarsus short, yellowish, basal 

 Joint less than half ol the tarsus, cylindrical, stouter than the following ones, of wbicb the 2nd is very short, 

 the jrd as long as the i>-t. I see no asymmetry of the end ol abdomen, but those parts are not in good 

 concution. 



Habitat : One specimen from [tajahy, S. Cattarina, S. Brazil, collected 1879, by Dr. F. Müller, to 

 whom the Museum i^ greatly indebted for interesting specimens and biological notices. 



The specimen arrived in a letter, and i*- a little crushed, peshaps flattened. It is the only wingless 

 specimen of Olyntha seen by nie. I suppose it to he i female, because no male genitals between the appen- 

 dages are to he seen, and the last ventral segment has a longitudinal furrow (or is perhaps split). These is no 

 female of Olyntha known; if the females are colored like the males, this specimen belongs to a new species. 

 The apparent indication of wings Iooks decidedly as when they au- abortive and will never be developed. 

 Therefore it can he assumed that the specimen is a female imago, or if winged females should exist, a 

 wingless form similar to those ol the Termitina >.

« Pale yellowish brown, basal Joint of anterior tarsi and bases of abdominal Segments more reddish; 

 every where clothed with short, line nairs. Antennae 17-jointed, about twice as long as head; head broadest 

 at eyes, broadly rounded behind; prothorax constricted in middle, broader behind than in front, where 11 

 tapers to a blunt point; mesothorax longer than metathorax, latter united to the intermediary segment; in 

 nymphs each bears a pair of wings longer than the segment. Abdomen as long as thorax plus head, the 

 terminal segment narrowed toward tip; cerci longer than terminal segment, the joints subequa] in length.

Cockerell, loc. eit. : 



« PlCTET in 1S54 deserihed Embia 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 oecurring at Florissant, having a strong general resemblance to .1 Termite, proves upon 

 careful examination to disagree in important particulars with all Termitidae, and to agree well with the 

 Embiidae, to wnich it must he referred. It has even the peculiar streaked appearance of the wings, so 

 characteristic of this family.
