Seidlitz, Heitter, etc. — the latter family has been abandoned as un- 

 tenHl)le, Pedilus, with which would go Ischalia, being referred to the 

 Pyrochroidae. 



With the Pyrochroidae, Ischalia agrees in the following cha- 

 racters : — Head constricted behind into a distinct thovigh stout "neck," 

 eyes large and emarginate in front for the insertion of the antennae, 

 thorax without a lateral carina (though the sharp depression of the disc 

 gives a false appearance of such), anterior coxal cavities widely open 

 behind, claws thickened at base; also in the soft integument and the 

 depressed form, widest towards the apex of the elytra. The principal 

 points of difference are that the thorax is not at all constricted at the 

 base and has the posterior angles prominent and even produced, and 

 the antennae are simple in both sexes. 



This relationship is probably best expressed by breaking up the 

 Pyrochroidae into subfamilies as follows : — 



1, Thorax more or less constricted at base, posterior angles obsolete 2, 



Thorax not constricted at base, posterior angles and median costa produced ; 



antennae simple 3. Isciialiinae. 



2. Antennae pectinate or flabellate in S , serrate in 5; form depressed, elytra 



usually broader behind 1. Pxjrochroinac. 



Antennae simple in both sexes ; form more convex and parallel. 



2. Pedilinae. 



Of these the Pyrochroinae include the majority of the genera, 

 the Pedilinae containing only Pedilus, while the Ischaliinae comprise 

 Ischalia and Eupleurida. 



The following two species from the Philippine Islands have recently 

 been received for determination from Professor C. F. Baker, Los Banos, 

 by whose generosity the types have been presented to the British 

 Museum. Though represented from Borneo (2 species), Java (1), and 

 Sumatra (1), the genus has not been hitherto recorded from the 

 Philippines. 



1. Isclialia dimidiafa, sp. n. 



Head, thorax, and basal half of elytra testaceous, apical half of the 

 latter deep blue ; antennae black, towards base with a deep blue metallic 

 tint; legs black or blue-black, the femora except towards the apex testa- 

 ceous; underside testaceous, with the abdomen dark blue. Thorax about as 

 wide as long, the sides obtusely angulate in the middle, the disc widely 

 depressed on each side of the median line, leaving only a sharply raised median 

 costa and marginal rim ; each depressed area with five minor depressions, 

 viz., three close to the median costa and two larger, towards the auterior and
