154 Mr. K. G. Blair on the Fabrician Types of 
with a not very dense clothing of depressed fulvous hairs ; 
eyes separated by a space about equal to the length of the 
secoud joint of the antenne ; thorax strongly transverse, 
with a shallow median impression gradually evanescent in 
front, and a moderately strong basal impression on each 
side, the surface rather closely but not deeply punctured ; 
elytra gradually narrowed from just behind the shoulders, 
deeply punctate-striate, the punctures much smaller behind 
the middle, intervals convex, finely not very densely aspe- 
rately punctate. Length 10 mm. 
The species is closely allied to L. puncticollis, Champ., from 
Guatemala, from which it differs in having the eyes less 
closely approximate and the punctures of the elytral striz 
coarser. The British Museum possesses specimens from 
Pernambuco, Bahia, Espirito Santo, and Rio de Janeiro. 
2. Homotrysis rufipes. 
Helops rufipes, Fab. Syst. Ent. p. 258. Nova Hollandia. 
Homotrysis (Allecula) angusticollis, Boh. Res. Eugén, 1858, p. 100. 
The synonymy has been established by Mr. H. J. Carter 
on specimens compared with the type of Helops rufipes, Fabr. 
This is another name that seems to have disappeared from 
recent catalogues. 
3. Lystronychus equestris. 
Helops equestris, Fab. Syst. Ent. p. 257. Brazil. 
The type is defective, wanting the head and thorax, but 
the elytra of this well-known species are amply distinctive. 
4, Heliotaurus ruficollis. 
Cistela ruficollis, Fab. Spec. Ins. i. 1781, p. 147. Lusitania, 
? Heliotaurus sanguinicollis, Reitt. Verh. Nat. Ver. Brinn. xlv. 1906, 
p. 143. 
The type is a 9, and is rather doubtfully identical with 
H. ruficollis of Reitter’s ‘ Bestimmungstabellen.’? The elytral 
epipleura are not turned upwards, but are vertical as in 
H. sanguinicollis, Reitt. 
5. Prionychus ater. 
Helops ater, Fab. Syst. Ent. 1775, p. 258. Liipsia. : 
No collection is definitely specified as containing the 
type, but the specimen in the Banks Collection bears a 
label with the above reference, and may, in default of any 
individual with a better claim, be taken as the type.
