224 Mr. E. W. Janson's Observations, S(c. 



5. Aplotarsus mar'il'imus, Curtis. 



If the insects placed in this genus by the late Mr. Stephens 

 may be considered typical, (and, seeing that the genus was 

 established by him for their reception, I hold such must be 

 the case,) the present species is certainly not an Aplotarsus ; 

 I have not yet been able satisfactorily to identify it with any 

 of the continental species of the genus Cardiophorus, with 

 which I have had an opportunity of comparing it, but to which 

 genus I think it is referrible, although departing somewhat 

 from the type in the unusual length of the antennae, but it 

 appears to have the prosternum abbreviated and compressed 

 at its apex, and the posterior thigh-covers are suddenly di- 

 lated within. I possess a single mutilated specimen, which I 

 obtained from Mr. Curtis. 



6. Cardiophorus formosus, Curtis. Mr. Curtis indicates its close 



relationship to Cardiophorus sex-punctatus of Illiger, and 

 which is probably too intimate to admit of specific distinction, 

 Illiger himself having given six varieties of that Protean 

 species. 



7. Aplotarsus ? cothurnatus, Curtis. This insect does not belong 



to the genus Ajolotarsus of Stephens ; it is the Ampedus suh- 

 carinatus of Germar, Zeitschrift, v. p. 177, No. 39 (1844), 

 where it is fully described : it is the Ampedus tibialis of Dejean's 

 Catalogue, under which name I have received it from Paris. 

 Specimens have been taken by Mr. G. Guyon, in Richmond 

 Park ; by Mr. S. Stevens at Tooting Common, and by myself 

 at Wanstead.
