. Coleoptera : general introduction and Cicindelidae and Paussidae. riin.e). The position and composition of this family have heen verymuch disputed. The formation of the tarsi in the greater numberof its members has caused it to be placed bymany authors with the Chrysomelid.e,with which however it has very little realrelation ; among other things the loop of themedian vein of the wings, which is one ofthe chief characteristics of the Clayicorxiagroup, is very distinct in Erotylus. The relation of this family to the Crypto-PHAGiDiE through the DACNijsrirc has long-been recognized, and there is much to besaid for placing the families together, someauthors having actually adopted this course.Fi«x. 51.—Episcapha Sharp (Biol. Centr.-Amer., Col. ii, pt. 1,indica. p. 579) practically says that he would have done so if the EiuxrYLiDiE of Central Americahad not previously been dealt with by Gorham; and Ganglbauer{Die Kafer von Mittel Europa, iii, p. 633) includes the Crypto-phagie.e under the Erotylid.e, of which he forms three sub-families as follows :—. 1. Anterior coxal cavities entirely closed behind Erotylijoe. II. Anterior coxal cavities open behind or atleast not entirely closed,i. Antennae inserted before the eyes under the side margins of the forehead .... Cryptophagin.33.ii. Antennae inserted between the eyes, thespace of forehead between themforming an angled or rounded process,which, in the middle, slopes more orless plainly towards the clypeus .... Atomariinje. Lacordaire observes (Gen. Coleopt. ii, p. 421) that the inclusionof the CryptophaGiDiE under the Erotyliile is all very well(il ny a rien qui blesse le sentiment des analogies) so far as EROTYLID.E. 109 the limited European fauna is concerned, but it is when we cometo deal with the exotic species, which must necessarily include theenormous number of tropical Erotylid.e, that the difficulty arises,for these by their size, general form, bright and varied coloration,Chrysomelid-like tarsi, etc., are co
