The amount of Mark on tlio elytra varies very much in this species. 

 Sometimes there is only a Mark, lateral spot, and an apical border 



parallel with the margin as in /,. elegans, hut generally the black at 

 the apex is suffused. Sometimes the lateral spot is more or loss 

 united with the black at the apex : it is 80 slightly in the type spe- 

 cimen ( 9 ) of A. latissimus, in the Linnean collection. The variety 

 /.. A irpago, Th.. has the two lateral spots united by a fascia. Variety 

 itratus, Murray, has this fascia and the black at the apex con- 

 tinent. Sometimes the elytra are entirely black except a yellow 

 fascia. 



The extent to which the elytra arc dilated in the male and the 

 fonn of the apical trnncature appear to vary considerably, while the 

 various systems of coloration above mentioned arc not constantly 

 accompanied by any one form of elytra. 



With regard to the synonymy given above, it must be noticed that 

 Fabricius does not mention the black in the middle of the thorax, 

 for which reason Gruerin (Rev. Zool., 1847, p. 227) provisionally re- 

 named the Fabrician insect Fabricii. There can, however, be little 

 doubt that the omission was an oversight on the part of Fabricius, 

 ially as the examples in the Banksian collection (said to have 

 i named by 1'abricius) are typical latissimus, the male example 

 having the lateral spot on the elytra partly united with the black at 

 the apex as in the Linnean type. 



The description given by Olivier applies well to latissimus, Linn. ; 

 but his figure (Ent., ii. 29, t. 1. f. 2) represents quite a distinct 

 species allied to L. ampliatus, Fahr., and is almost certainly the male 

 of the species which he names L. proboscideus* (Ent., ii. 29, p. 8, 

 t. 1. f. 6). 



BROXYLUS. 



Rostrum none. Apical joint of palpi very large, long, knife- 

 shaped. Antennae very compressed, simple. Thorax with an in- 

 terrupted mesial carina. Elytra very ample, inflated, quadricostate, 

 the interstices divided into subquadrate spaces by transverse carinas. 



The species upon which this genus is founded closely resembles 

 Calopteron dilatatum, Bourgeois, but differs in the form of the palpi. 



* This species as well as ferrugineus, Fab., lateralis, Dalm., and perhaps 

 some other Fabrician species of Lycus, appear to be omitted from Gemminger 

 and v. Harold's Catalogue of Coleoptera.
