which are directed, one in front, the other behind : the first of 

 these branches becomes the axis of the glandular tubes of the 

 jirst order so-called ; the second enlarges to form one or two 

 oval reservoirs, into which there open some hundreds of glan- 

 dular tubes of the second order so-called. These latter are 

 barely 60 p, in diameter ; they are but a third of the size of 

 the others, but four times more numerous. 



In the genera Ephippigera, Meconema, &c. I have noticed 

 in the midst of the tubes of the second order a special bundle 

 more strongly coloured, formed by half a dozen caeca. 



Lastly, in the Locustidae there is to be found a pair of 

 prostatic glands with a lenticular appearance. 



In the Mantidae there are four kinds of appendicular 

 organs : — 



1. Some fifty tubular caeca which are glandular. 



2. About twenty shorter cseca gathered into knots, which 



are also glandular in character. 



3. A pair of large vesiculae seminales, which are concealed 



by the organs before mentioned. 



4. A pair of prostatic glands. 



From the histological point of view all these organs are, as 

 a rule, made up of a single layer of cells supported on a 

 basilar membrane ; around the vesiculse a peritoneal envelope 

 is plainly visible. 



There is a further remarkable fact, namely the development 

 of very tiny crystals in the glandular tubes just before 

 copulation. 



LXV. — New Species o/Tyralidae from the Khasia Hills. 

 By W. Waeren, M.A., F.E.S. 



The types of the species now described are, like those of my 

 previous papers, in the possession of the Hon. Walter Koth- 

 schild. The majority, as will be seen, are from the Khasia 

 Hills, a district whose richness appears to be by no means 

 yet exhausted.

Subfamily Cebtbauqinje.
