TRYPHONIN^E -A REVIEW. 



BY HENRY LORENZ VIERECK. 



Mr. Claude Morley has favored the entomological world 

 with another volume of his Ichneumonologia Britannica, being 

 volume iv of his British Ichneumons, Tryphoninse, and set 

 forth in text and figures comprising pages i-xvi, 1-344, one 

 plate, and many figures. 



Th,is compilation will no doubt be consulted by many a 

 student of insects and not vainly, for a mass of facts has 

 been painstakingly gathered and arranged, while some genera 

 have been figured that have previously been known to science 

 only by descriptions. 



In view of the circulation that the present book is likely to 

 have, it is the more unfortunate that the author did not lay 

 down his work more securely, as, for example, with reference to 

 the genera there is an evident disregard as to foundationstones. 



Forty-nine genera are treated, of which one is a new r genus, 

 and a blanket genus at that, including a number of old genera 

 that by some writers have been regarded as good and distinct. 

 The new genus is Homocidus and is evidently a mixture of 

 many species belonging to Zootrephes, Syphoctonns, and 

 ffomotropus, and possibly Ein'zemnm and Aniarophrov. If 

 these genera are to be fused then Zootrephes must be used and 

 a new genus is uncalled for. For the present Homocidus 

 Morley, for which I designate Hor.iocidns r/Vffff/s Gravenhorst 

 as type, sinks as a synonym of Homotropus (Foerster) Davis, 

 for which latter I designate Bassus bzcapt'llarisW&lsh as type. 

 In the table of genera Homocidus is represented as wanting 

 notauli, but in the table to species under the same genus are 

 to be found two categories, one with notauli present, the other 

 with notauli wanting ! 



Bassus is credited to Fallen instead of Fabricius, who erect- 

 ed the genus. According to Curtis's fixations of types Bassus 

 Fabricius can not be used for Bassns Authors, which latter 

 should be called .\uonialon J urine. Anomalon Authors being 

 without a name may be called Paranomalon new genus, with 

 Op/iion flarifrons Gravenhorst as type. 



The type of Acrotowus Holmgren has never been fixed, so 

 Trvphoii Incidnlns Gravenhorst is 1 hereby designated as type. 



Addognathus Holmgren : No type designated. Type Acielog- 

 nathns brcz'i conn's Holmgren, by present designation. 



Catoglyptus Holmgren: No type designated. Type Meso- 

 leptus fortipcs Gravenhorst, by present designation. 



Chdrinaus Holmgren : No type designated. Type Exochus 

 funebris Gravenhorst, by present designation.
