lower of which constitutes a sheath for the upper which is flagelliform. 

 A single 9 example of what is either the same or a closely allied 

 species was bronght from Macassar. There appear to toe slight differences 

 in the form of the keels between it the Javan form , but without 

 knowing the male, I refrain from establishing another species for the 

 reception of this specimen. 



65. Strongylosoma conspicuum, sp. n. PI. XXII, fig. 9. 



Java: Buitenzorg. Two cT examples. 



Closely allied to the preceding; but differing as follows. 



The body is more slender (length 33 mm., width 3.7); the keels 

 are a little larger and more yellow i. e. the black of the dorsal surface 

 does not spread on to them at the base at it does in weberi. The 

 caudal process is larger and more yellow, with its sides parallel and 

 not converging, approaching what is seen in Leptodesmus. 



66. Strongylosoma atro-roseum, sp. n. 



Java: Buitenzorg. A single Ç example. 



Colour; head brown, paler below; antennae infuscate; dorsal surface 

 brown , keels and caudal process of a yellowish-pink tint ; lateral surface 

 pale brown above, fading into yellow below; legs and sterna flavous. 



Head smooth and sulcate above; antennœ moderately long. 



First tergite convex , anterior border convex from side to side, keeled, 

 anterior angle of keel very obtuse, posterior angle nearly rectangular, 

 its posterior border directed slightly backwards. The keel of the second 

 considerably below that of the first and of the third, anteriorly and 

 posteriorly produced. Keels of third and fourth well developed, with 

 rounded anterior and acute posterior angles. Keels of the rest above 

 the middle of the side, well developed, with thickened margins, 

 rounded anterior angle, and acute posterior angle; the posterior angle 

 of the fifth about on a level with the posterior border of the tergite , 

 those of the rest becoming progressively more and more produced 

 from before backwards. The pores situated on the lower edge of the 

 lateral surface of keels. The dorsal surface smooth, only very slightly 

 polished. The transverse sulcus nearly straight, rather shallow, not 

 punctured. The anterior groove not sculptured. Lateral surfaces nearly 

 smooth and shining, only at the anterior end of the body very finely 

 granular below. Inferior crest only present on the 2 nd , 3 nd and 4 th . Caudal
