HETEROMERA. 547 
formed in both sexes, with joints 9 and 10 transverse ; prothorax transverse, the sides a little rounded, 
and armed at the apex with a long, outwardly projecting, obtuse tooth (forming the anterior angle), 
between which and the base are five short teeth (the posterior one forming the hind angle); legs rufo- 
testaceous ; anterior tibie with a distinct tooth about the middle beneath in the male. 
Length 23-24 millim. (¢ 9.) 
Hab. British Hoypuras, R. Hondo (Blancaneaur) ; Guatemaua, Cubilguitz (Cham- 
pion). 
Four examples. Closely allied to P. (Storthephora) auritus, Makl., from Brazil, and 
P. denticulatus, Ch., from Chiriqui; it differs from the latter in having the anterior 
thoracic tooth less oblique, more obtuse at the apex, and more prominent, the 
other teeth shorter. The anterior tooth projects outwards to far beyond the eyes, and, 
owing to the other teeth being short, it is apparently longer than in P. denticulatus. 
The description of Storthephora aurita nearly agrees with P. denticulatus, except that 
the smaller thoracic teeth appear to be longer (the ante-apical one being very promi- 
nent) in the Chiriqui insect. 
Paratenetus tropicalis (p. 243). 
To the locality given, add :—Mextco, Motzorongo (Flohr), Jalapa (Hoge), Teapa in 
Tabasco ([ége, H. H. Smith); British Honvuras, Belize (Blancaneaux) ; GUATEMALA, 
near the city (Champion, Salvin), Duefias, Zapote (Champion); Panama, Taboga I. 
(Champion). 
Numerous specimens of a small Paratenetus from the above localities are perhaps 
referable to P. tropicalis, Motschulsky. They agree with his few words of description, 
but differ greatly from his figure (t. 3. fig. 7), which represents a very different insect *. 
These specimens resemble P. denticulatus and P. sexdentatus in size and sculpture, 
and in the rather small club to the antenne, but they have the thorax very finely 
denticulate at the sides and without prominent tooth at the anterior angle. The 
antenne are considerably longer in the male than in the female, with the club not very 
stout; the latter varies in colour from entirely ferruginous to pitchy-brown, sometimes 
pitchy-brown with the apical joint testaceous, and joints 9 and 10 are more transverse 
in the female than in the male. ‘The anterior tibize in the male are unarmed. 
ACROPTERON (p. 252). 
Acropteron agriloides (p. 255). 
To the localities given, add :—Mexico, Omilteme in Guerrero, Teapa in ‘Tabasco 
(H. H. Smith), Tapachula in Chiapas (Hoge). 
* This figure (7) is, perhaps, intended for Terametus capicola, Motsch. As regards the antenne, the figure 
(76) agrees with the male of our insect. In several other cases the figures quoted by the author in the text 
do not agree with the plate.
