DiRCAEA Fabr. 



The characters used by Seidlitz (Naturg.Ins. Deutschl., v,2, 1898) 

 to separate Dircaea from Phloeotrya are the non-serrate maxillary 

 palpi, with the apical joint broader than the others, and the short 

 antennae, with joints 3-10 sub-triangular. Bircaea is thus restricted 

 to two European species and the N. American D. littirata Lee, all of 

 which have flavo-maculate elytra ; D. mexicana and jjt/ivewfr/s Champ., 

 from Central America, D. velutiva Champ., from Australia, and the 

 seven Japanese forms described by Lewis in 1895, belonging to 

 Phloeotrya. D. validicornis Lewis approaches Dircaeomorplia Fairm. 

 (1896), type B. clavlcornis, from Pedoug. B. longicornis Champ., from 

 Mexico, would be best placed in Serropalpus, owing to its long, slender 

 antennae, the substriate elytra, the simple penultimate joint of the 

 posterior tarsi, the imnotched posterior tibiae, and the absence of the 

 sharp oblique ridge on the front of the propleura ; the type, cf , however, 

 cannot be said to have strongly serrate maxillary palpi. B. (Hyjmlus) 

 hicmcta Horn, from California, as already stated, is an Ahdera, 

 B. venusta Champ. (= lignivora Lea), from Austi'alia and Tasmania, 

 must be referred to a separate genus, with some allied tropical 

 S. American forms. In the " Biologia," Phi oeoh'y a 'wa,ii treated as 

 synonymous with Bircaea, but the name is here used for the various 

 S. American forms described below, all of which are related to the 

 European P. vaudoueri. 'No important sexual difference has been 

 observed in the form of the maxillary palpi, except that the apical 

 joint is in some species more elongate in ^J than in ? .

According to Fauvel (Rev. d'Ent.,xxiv, p. 237, 1905), Megajmlpus 

 (type M. sexguttatun Montr., from Lifu) = Phloeotrya, under which he 

 described two new species from New Caledonia. This identification 

 seems to me to be extremely doubtful, but it is not improbable that 

 the genus here named Ca.llidlrcaea (infra) is synonymous with it.

P. rtifipea Steph. {nee Cyll.) (^ stepiiemi Jacq. Duv.) should bear 



the name P. vaudoueri Muls. (1856). Gryllenhal's species, two specimens 



of which are before me, is a smoother, smaller insect, with shorter 



antennae, the third joint of which is veiy little longer than the second.
