Description of Lectotype here Selected. — Size large for the genus; 

 form elongate fusiform. Head rather small, depth subequal to 

 greatest width, depressed dorsad, moderately protuberant between 

 the antennal bases, without an appreciable vertical sulcus; eyes 

 subpyriform, somewhat prominent laterad when viewed from the 

 cephalic aspect. Maxillary palpi with the distal joint very elongate, 

 slightly longer than the preceding joint, trumpet shaped, the distal 

 margin very obliquely truncate, the length of the truncation con- 

 tained over twice in the next shortest side. Pronotum subdeplanate 

 dorsad, in proportions subquadratc, the lateral lines of the disk 

 weakly subconvergent cephalad; cephalic margin strongly arcuato- 

 emarginate, the head well seated in the same, caudal margin sub- 

 truncate, very faintly and very broadly subemarginate mesad; 

 dorsum passing into the lateral lobes without lateral carina?, but with 

 appreciable angles caudad; lateral lobes with the greatest depth 

 contained about three times in the greatest (dorsal) length of the 

 same, ventral margin of lobes straight, becoming obliquely sub- 

 arc uato-emarginate in the caudal half. Tegmina absent. Abdomen 

 slightly deplanate dorsad, elliptical in outline. Subgenital plate 

 small, subrostrate, very slightly arcuato-emarginate mesad. Ovi- 

 positor equal in length to the abdomen, subequal in length to the 

 caudal femur, of moderate depth, slightly arcuate dorsad in the 

 proximal third, thence straight, apex with very small impressed 

 puncta. Cerci elongate, tapering. Cephalic tibia? with a distinct 

 but small elliptical tympanum on the cephalic face. Median limbs 

 similar in proportions to the cephalic. Caudal femora moderately 



48 Both of the types have lost all of their limbs, and the characters of these 

 partB are supplied from practically topotypic material.
