new Species of Diploptera. 10.3 



thorax granular and rather more coarsely punctured ; apex of 

 first abdominal segment with coarse longitudinal striations 

 on ventral surface. 



Length 1(H mm. 



Hah. Gyangtse, 13,000 ft. ; Khamba Jong, Sikhira, 

 13,000-16,000 ft., Tibet Expedition [H. J. Walton). 



$ . Clypeus, a spot between anteuuse at base, sulphur- 

 yellow ; apex of femora, tibiae, and tarsi yellow. Each side 

 of anterior margin of pronotum produced to form a spine. 



Length 8 mm. 



A number of ? and 6 S • 



Odynerus (Hypodynerus?) hh'stitus, sp. n. 



Niger, dense pilosus ; abdominis segmentorum 1, 2 margine postico 

 pallide flavis. 



? . Black j clypeus, a minute spot on each side above it, 

 a minute spot behind each eye, a broad band on the apical 

 margin of segments 1 and 2 of abdomen dorsally, whitish 

 yellow. Wings hyaline ; fore wings fuscous along the costa, 

 more faintly fuscous towards the posterior margin. Covered 

 with long dense black hair, densest on vertex of head and 

 thorax, more sparse on abdomen. Tibiae and tarsi with 

 dense golden-brown pubescence. Flagellum glabrous. 

 Clypeus flat, truncate, narrowly produced towards the apex ; 

 head narrow when compared with thorax at tegulse; anterior 

 angles of pronotum obtuse; median segment truncate, slightly 

 depressed medially ; a conspicuous fold at base of second 

 abdominal segment beneath ; first abdominal segment broadly 

 bell-shaped, as broad at apex as second abdominal segment 

 at base. Head and thorax granular and coarsely punctured, 

 clypeus and abdomen more finely ; mesonotum with four 

 inconspicuous longitudinal furrows of varying length ; tegulae 

 shining, impunctate. 



Length 10 mm. 



Hub. Khamba Jong, Sikhim, 15,000-16,000 ft., Tibet 

 Exped. {H.J. Walton). 



Strongly resembles the insects of Saussure's Division 

 Hypodynerus, all of which come from Chili and the western 

 face of the Andes. The long hairy coat, the whitish -yellow 

 markings, and the fold at the base of the second abdominal 

 segment beneath are all characteristic of the Chilian insects ; 

 the wings and feet, however, lack the reddish coloration of 

 Hypodynerus, in which division I place it with doubt.
