ample and shorter wings, as well as by a striking difference 

 in the form of the nervures, where the areolet is situated 

 when present, and by the thicker posterior legs, their tarsi 

 being generally more or less incrassated in the males; but in 

 a new species which I shall describe, and also in T. tenuitar- 

 sum^ they are not thickened. 



Having published the genus Anomalon before Graven- 

 horst's work appeared, it may appear necessary to give my 

 reasons for rejecting some of his names in the Guide. 1st 

 Bassus of Fabricius is Gravenhorst's 3rd family of Cryptus, 

 seductorius being the type given in the Piezatorum ; 2ndly, 

 Jurine's 1st family of Anomalon, which of course is his type, 

 Gravenhorst has called Bassus. 3rdly Jurine's 2nd family of 

 Anomalon I have called Theuion, because it is not the typi- 

 cal Anomalon. 



1. Scut elliim yellow or ferruginous. 



1. enecator Rossi. — Grav. Ichn. Europ. 3. 641. 110. 



I cannot remember the localities of this species, 5. and 9. 



2. circumflexum Linn. — Don. 3. jjI. 93. f. 2l 



Taken at Darent: I believe it has been bred from the 

 caterpillars of Sphinx Ligustri. 



2. Scutellum black, rarely rufous. 



3. amictum Fab. — Curt. B. E. pi. 736 S. a little magnified. 

 For the specimen figured I am indebted to Mr. C. Lyell, 



who took it at Kinnordy in Forfarshire. 



4. xanthopus F. — Grav. p. 652. no. 116. June, Darent. 



5. ruficorne Grav. 655. no. IIG^. 'Netley, Salop, Mr. Hope.* 



6. cerinops Grav. 658. no. 118. — flavifrons Grav. Uebers. 

 I think I took it at Dover. 



7. flaveolatum Grav. 664. no. 122. — auricapillus Gmel.?

8. tenuicorne Grav. 671. no. 125. 



Coomb Wood, on oaks; males in May, females in July.

Male ferruginous ; head and thorax, a streak on the 2nd 

 abdominal segment, and 3 apical joints black : antennae 

 very long and slender, brown, ferruginous beneath to the

11. tenuitarsum Grav. 683. 7io. 133. 



I think it was this which Mr. Dale bred from pupae of 

 Episema cceruleocephala. 



Dr. Balfour of Edinburgh obligingly communicated speci- 

 mens of the Coral-rooted Boat-lip, Corallorhiza innata^ from 

 Ravelrig bog, where they were found growing last July.
