irregularly. Post- and anteclypeus well developed and separated from 

 one another. Mandibles strong, with five teeth. Antennae, ommata, 

 maxillae, labium, hypopharynx, and fusulus normal. For distribution 

 of epicranial tubercles, twelve setigerous and four without setae on 

 each hemisphaerium, see pi. VII, f. 20, where they are numbered after 

 Dyar's and Forbes' schemes ^■'). 



Subdivisions and s с 1 e r i t e s of the thorax and abdomen (pi. 

 VIII, ff. 23 — 26) bearing setae and tubercles of ar ather normal scheme. 

 Sclerite of pronotum rather weak; two pairs of minute tubercles, with 

 no setae, lying about the medial line of it, probably, correspond to the 

 praedorsal tubercles of abdominal segments; two pairs of setige- 

 rous tubercles on the fore margin correspond, probably, to the subdor- 

 sal anterior sclerites; two pairs of such near the posterior margin cor- 

 responding then to a pair of the subdorsal posterior sclerites. Proepi- 

 merum well marked and bearing above stigma a suprastigmatal tuber- 

 cle and before it two setae of indistinct homology. Three pairs of 

 sclerites, with four pairs of setae, on mesonotum could be homologi- 

 zed with subdorsal anterior (lateral and anterior pair) and posterior 

 sclerites (medial and posterior pair). Location of setae on the metano- 

 tum being nearly the same as on mesonotum; the suprastigmatal tu- 

 bercle distinct (tubercle on the lower posterior angle being enigmatic). 

 Tubercles and setae on seven basal abdominal tergites developed in a 

 typical scheme: well marked praedorsal pair, subdorsal anterior and 

 posterior and suprastigmatal, each, except praedorsal, bearing a seta; 

 pleurites having sub- and poststigmatal tubercles. The subdorsal sclerites 

 of the eighth segment fused together in one pair; supra- and substigma- 

 tal setae well developed. On the ninth segment all subdorsal and 

 suprastigmatal sclerites fused together in one, bearing a series of six 

 setae: subdorsal posterior (median pair), suprastigmatal (lateral) and 

 subdorsal anterior (intermediate pair). Tenth tergite bearing three pairs 

 of setae, one of which large, greatly hypertrophied and curved. 



Chaetotaxy of the ventral sclerites (pi. VIII, ff. 25—26) is also 

 rather typical. Pro-, meso- and metacoxae bearing three setae, with 

 one pair between them, this latter, probably, corresponding to the 

 intrapodal pair. Laterally from the coxa a minute sclerite is situated, 

 probably, extrapodal. First abdominal sternite bearing well developed 

 praeventral, intrapodal (fused in one), extrapodal (with one seta), supra- 

 ventral (with one seta) and substigmatal pairs of tubercles. Second 

 abdominal sternite having the intrapodal pair not fused and extrapodal 

 ones bearing each two setae. Sternites third, fourth, fifth and sixth 

 being identical as to the position of tubercles and setae: praeventral 



"') Except one of dorso-lateral tubercles situated between V and VIII.
