to eighth inclusive cylindrical, ninth to eleventh consider- 

 ably wider, forming a loose club. Mandibles stout and 

 curved. Mentum of males of some species with two tufts of 

 hairs arising within fovese, of females with two fovese. Thorax 

 transverse, margins even or denticulate, anterior angles varia- 

 ble, anterior coxal cavities small, closed behind. Abdomen with 

 five visible ventral segments, the first longer than any of the 

 succeeding. Legs not long, rather stout, claws simple. 

 Type genus, Elacatis Pascoe, 1860. 



The material considered in this paper falls into two 

 genera, which may be distinguished inter se by the following 

 characters : 



Eyes evenly rounded before and behind, anterior angles of thorax not 

 covered by the eyes, lateral margin of the thorax with denticles. 



Elacatis Pascoe. 

 Eyes developed posteriorly so that they overlie the anterior angles of 

 the thorax, lateral margin of thorax without denticles.

Generic characters. — Elacatidse with eyes anteroposterior^ 

 symmetrical, lateral margin of thorax with three to seven den- 

 ticles, second segment of antenna globular, terminal segment 

 of labial palpus sharply truncate, terminal segment of maxil- 

 lary palpus twice as long as broad (Plate 1, figs. 1, 2, 5, 6, 7) . 



Genotype, Elacatis delusa Pascoe. 



There are three species belonging to this genus before me, 

 which may be distinguished as follows: 



1. Middle portion of presternum with a few indistinct punctures, lateral 



portions with punctures somewhat confused- E. bakeri sp. nov. 



Presternum evenly, coarsely punctured 2. 



2. Pronotum with a median smooth line, rest of surface finely punctured. 



E. undulata sp. nov. cum subsp. nov. 



Pronotum evenly, very coarsely punctured, no median smooth line. 



E. delusa Pascoe cum subsp. nov. 

 Elacatis bakeri sp. nov. 



Head finely and densely punctured, eyes finely granulate; 

 somewhat brassy above, piceous beneath ; mentum bif oveate, an- 

 tennae piceous, reaching just beyond anterior margin of thorax ; 

 thorax broader than long (7 : 10) , convex, lateral margins 

 low on sides with four very feeble denticles, surface densely 

 and rather coarsely punctured, dark piceous with brassy luster, 

 scutellum small, elytra tapering evenly to tips, rather more
