The two known Burmese genera may be further recognised 

 as follows : 



a. Pores manifest, on segments 5, 7, 9, 10, 12, 13, 15, 16, 



17 and 18: head covered by a semicircular expansion 

 of the first tergite; antennae long; legs short, with 

 trochanter equalling femur in length; sternal areas 

 wider and transversely sulcate Cryptodesmoides 



b. Pores invisible: head not covered, with shorter and 



stouter antennae ; legs very long and slender , the 

 femur three or four times the length of the trochanter, 

 sterna narrow, longitudinally sulcate Trichupeltis. 



Genus Cryptodesmoides, nov. 



2. Oryptodesmoides feae , sp. n. 



(Fig. 1) 



Colour a dull pale brown throughout, a little darker on the 

 upper surface of the back. 



Head at most only very finely granular above, hairy below, 

 frontal sulcus obsolete. Antennae tolerably long, the 5**" and 6'" 

 segments the thickest and subequal in size, the S"""^ about as 

 long as the P"^ and 2"'^ taken together, 4"' about half the length 

 of the S""*, T^ small and cylindrical. 



pt tergite with anterior border evenly convex , about the 

 third of the arc of a circle, expanded into a hood covering the 

 head, posterior border straight in the middle and produced 

 obliquely forwards and outwards at the sides, the upper surface 

 sloped evenly downwards and forwards, the posterior elevated 

 part furnished with two rows of tubercles, the anterior hood-like 

 part radially sulcate. The rest of the keels depressed, following 

 the slope of the back, those of the somites between the 2^"* 

 and 5"" directed obliquely, but less and less, forwards, those of 

 the IT"", 18'" and 19"" directed backwards, the rest directed at 

 right angles to the long axis of the body, only very slightly
