longitudinally striated ; the metanotiun more finely and closely than it ; 

 the striae on the forks stronger and carved ; the space at the apex between 

 them has 2 stout keels on either side and a finer roundly curved one at the 

 apex ; there are some broken keels between . The central part 01 the lower- 

 region of the metanotum is finely, closely punctured . Upper part of pro- 

 pleurae densely covered with a longish white pile ; below is a stout curved 

 keel, with a curved depression above ; on the upper central part of the rneso- 

 pleurae are some fine curved longitudinal striae ; below are 2 long upper and 2 

 shorter lower keels. Abdominal petiole twice the length of the hind coxae. 



Holcokapala, gen. n. 



Female. Antennae short, stout, 10-jointed, the 3rd, 4th and 5th antennal 

 joints longer than wide, of equal length ; the last conical, longer than the pre- 

 ceding. Mesonotum transversely striated ; the scutellum smooth, a wide deep 

 furrow, widened towards the apex ; the processes stout, extending close to the 

 apex of the abdomen, curving and converging at the end. Metanotum with 

 an oblique slope, smooth. Abdominal petiole about 3 times longer than wide 

 and as long as the hind coxae. Apex of clypeus margined, transverse, the sides 

 rounded ; the sides above are foveate. Malar space as long as the eyes. 

 Ocelli in a line. Head striated above ; it is bare ; the thorax pubescent ; 

 parapsidal furrows distinct ; the middle lobe of mesonotum has a shallow 

 furrow down the middle. Pleurae almost smooth. 



Comes near to Lasiokapala, which has the head and scutellum processes 

 smooth, the latter long and extending beyond the apex of the abdomen. 



Holcokapala striaticeps, sp. n. 

 Black, the mandibles, antennae and the 3rd and following segments of 

 the abdomen rufo-testaceous ; palpi dark testaceous ; legs, except the coxae, 

 yellowish testaceous ; the basal part of the abdomen has a blue tint ; wings 

 hyaline, the nervures pale testaceous. Female. Length, 4-5 m.m. 



Sides of front and vertex finely closely longitudinally striated, the striae 

 curving outwardly below, the striae on the malar space stronger, somewhat 

 rounded and transverse, the outer orbits longitudinally striated. Basal part 

 of mesonotum strongly irregularly striated, more closely and regularly on the 

 base than on the apex ; the apical part is smooth as is also the scutellum. 

 The processes are stoutly striated from the base to the apex. Metanotum 

 smooth, its sides bordered b_y keels which roundly curved and unite at the 

 bottom below. Propleurae excavated, bordered by a rounded keel near the 

 top. Mesopleura3 irregularly weakly longitudinally striated ; the lower apical 

 part is much more finely and regularly striated ; the mesosternum is bordered 

 by a weakly crenulated furrow, and there is a vertical one on the base of the 

 apical fourth, commencing near the top. Metapleurae irregularly reticulated. 



Diccelothorax parviceps, sp. n. 



Black, the 2nd and 3rd segments of the abdomen tinged with violaceous ; 

 the mandibles, antennae and the greater part of the 4th and following ab- 

 dominal segments rufo-testaceous, the apical half of the femora, tibiae, tarsi
