CORYLOPHID M. 



— PSEUDOCORYEOPHID.E. 



B9 



contracted in front ; the sides of the segments in the former are set 

 with strong forked setae, and in the latter are separately prolonged 

 into short blunt processes, terminating in setae. The pupae are 

 of ordinary form. 



The species are found in and under dry or rotting wood or 

 bark, in decaying vegetables, hotbeds, fungi, etc. Orthoperus 

 atomarius appears to be confined to cellars, where it feeds on the 

 fungus Zasmidium cellare. 



The species are probably very widely distributed throughout 

 the world ; species of Sacium, Arthrolips, Anisomeristes, Serico- 

 derus, Gorylophodes and Leiuisium have been described from Ceylon, 

 and one species of Arthrolips from Burma. 



The Coryeophid^; have strong affinities with the Siephid.e, 

 has been pointed out by the Rev. A. Matthews, who has studied 

 the group more than any other writer, and they are also closely 

 allied to the Trichopterygedve. 



[Family 22. PHiENOCEPHALID^.] 



Minute insects; aniennce 11-jointed, the last three joints forming 

 an elongate club; head sessile, large and broad, deflexed ; mcuvillce 

 bilobed with the lobes short ; epimera of the mesosternum moderate ; 

 all the tarsi four-jointed, ivith the three basal joints of equal length, 

 bilobed. 



Mr. Matthews, who described this family, considers it as the 

 connecting link between the Coryeophid^e and the Silpiiid.e ; 

 it comprises the single genus Phcenocephalus, which contains one 

 species from Japan ; it appears to be more nearly allied to the 

 Trichopterygill*; than to the Corylophidje, but it is quite 

 distinct from both of them. 



[Family 23. P8EUDOCORYLOPHID2E.] 



Minute insects ; antennw apparently 9-jointecl, but really 11 -jointed, 

 the last three forming an apparently solid club ; head large, retractile ; 

 macvillai trilobed as in the TRiCHOPTERYGiDiE ; epimera of the meso- 

 sternum very large; urngs ample, broadest at base, with distinct 

 veins; all the tarsi 3 jointed ; cdl the coxce rounded and widely 

 distant. 



This aberrant family is related to Trichopterygid^e, Silphidje, 

 and CocciNELEiuiE, and appears to be quite distinct from the 

 Coryeophid^e. It comprises one genus Aphanocephalus, Woll., 

 comprising six species ; one from Brazil, and the remainder from
