and fused with the last dorsal segment, shows beyond doubt that 

 it must be ranked in the Lahiduridcp.. A new genus and new 

 subfamily are consequently required for its reception. 



Genus PALEX, n. g. 



Entire body strongly flattened. Antennae with 19-20 segments, 

 the first long and subeonical, second minute, third long and cylin- 

 drical, fourth globular, fifth and sixth ovate, the latter a trifle longer, 

 seventh cylindrical, longer, but shorter than third, the remainder 

 cylindrical, gradually lengthening. Head smooth and depressed. 

 Pronotum subquadrate, but convex anteriorly. Prosternum 

 parallel-sided, scarcely constricted ; meso- and metasterna about as 

 broad as long, more or less rounded, and truncate posteriorly. 

 Elytra perfectly developed but rather short, rounded at the apex ; 

 feebly developed at the axillary angles, thus exposing a small 

 scutellum ; no keel. Wings short but usually visible. Legs not 

 very long ; femora broad and compressed ; tibice short and 

 slender; tarsi slender, first segment short, the third longer than 

 first and second united. Abdomen strongly depressed ; no lateral 

 tubercles. Last dorsal segment ample, simple. Penultimate 

 ventral segment quadrate, triangular. Pygidium short, broad, 

 adpressed, vertical, fused with dorsal segment and with no marked 

 suture. Porceps remote at the base, broad, nearly straight at 

 first, then bowed. 



This curious genus has no resemblance whatever to any other 

 known Labidurine form, but owing to the build, coloration and 

 strongly flattened body, may be easily confused with the 

 Sparattince. 



The single known species, which is therefore the type, occurs 

 in the Oriental Kegion. 



28. Palex sparattoides, Bonnans. (Fig. 77.) 



Platylabia sparattoides, Bonti. (OQi) j). 459 ; Kir/>tj, (04) p. 22. 



Brown or blackish, very strongly depressed. Antennte with 

 20 segments, brownish, yellowish, paler towards the apex ; basal 

 segment darker ; third segment cylindrical ; fourth only about 

 half as long as the third ; fifth a little longer than the fourth ; rest 

 longer, cylindrical. Head depressed, posterior margin sinuate. 

 Pronotum with anterior margin decidedly convex, sides straight, 

 posterior margin straight, angles rounded ; reddish brown. Elytra 

 brown, coriaceous. Wings of same colour and texture as the elytra. 

 Legs yellowish. Abdomen strongly depressed, chestnut, slightly 

 widened towards the apex ; lateral tubercles absent. Last dorsal 

 segment ample, in the c? quadrate, posterior margin truncate, flatand 

 smooth ; a little narrower in the $ . Penultimate ventral segment 

 in the 6 ample, rounded, very gently emarginate in the middle of 

 \)Osterior margin. Pygidium: in the d" scarcely prominent, trans- 

 verse, with a vertical face ; in the $ slightly larger, witn a minute
