Further Notes on Telephorid(B. By G. R. Crotch, Esq. 



Since T first made a coramunication to the 'Entomologist' 

 (ii, 167) on the characters of the Telephoridae of Great 

 Britain, I have been able to study them more attentively, 

 and have received numerous types from abroad, as well as 

 many British specimens. I have no new species to record 

 as yet, but a correction to point out, and also to indicate 

 some new characters of considerable service in determining 

 the limits of their variation. I allude here to the impressed 

 smooth line on the joints of the antennae in the male, hitherto 

 noticed by Thomson only, even Mulsant passing it over with- 

 out notice. It is not at first readily visible, especially in 

 carded specimens, where all characters of antennae are gene- 

 rally received, but along the external edge of the fourth and 

 following joints generally exists a small smooth fovea : in 

 the light it is sometimes very conspicuous. The number of 

 joints on which this is present will serve to divide the 

 species. 



1. Antennae sin)ple in both sexes. Fuscus, vusticus, rufus. 



2. 4th — 8ih joints impressed. Nigricans. 



3. 4th — 9th „ „ Flavilabris, thoracicus, la- 



teralis. 



4. 4th — 10th „ „ Lividus, figuratus, bicolor. 



5. 5th — 9th „ „ Haimorrhoidalis. 



6. 5lh — 10th „ „ Pellucidus, obscurus, palu- 



dosus. 



7. 6th — 11th „ „ AssimiHs, Pk. 



The above table is compiled from Thomson's work, but I 

 have verified in nearly every instance. 



Some of our closely-allied species will thus be seen to be 

 widely separated, and the variable T. rufus may be always 

 recognized by its simple antennae. T. assimilis, P/t., is the
