MALACODERMATA. 235 
excisa, coleopterorum latitudine, lateribus antice fortiter angustatis valde reflexis ; elytris tricostatis, 
costis basi flavescentibus, intervallis leviter obsolete reticulatis, tertio per lineam vix diviso. Antennis 
compressis, vix serratis, Long. 13 millim. 9°. 
Hab. Mexico (Sallé, coll. Sturm), Mexico city (Hoge). 
This species, though belonging to the same section of the genus as C. difficile and 
about equal in size to the largest females of that species, differs in the structure of the 
thorax, which is larger and wider, and the carina, though divided, is not open to the 
base, but unites again at the point where the excision of the base meets it. The 
reticulation of the intervals is similar to that of C. difficile or C. miniatum, viz., very 
fine, irregular, and obsolete. Only two specimens have yet been found by me among 
the large numbers of Caloptera I have seen, and they are both females. The one from 
Sallé’s collection is figured. 
28. Calopteron notatulum. (Tab. XI. fig. 5.) 
Nigrum ; prothoracis lateribus elytrisque dimidio basali lete aurantiaceis, his postice paullulum ampliatis, 
tricostatis, plaga scutellari nigra; antennis corporis fere longitudine, serratis, articulo apicali flavo. Long. 
82-9 millim. 
Hab. Guatremaua, Pantaleon, San Isidro (Champion); Panama, Bugaba, Volcan de 
Chiriqui (Champion) 
Not differing very strongly from C. tricostatwm, but the clear yellow apical joint of 
the antenne, in addition to the well-marked scutellar patch, are, I think, indications of 
a distinct species; the thoracic carina is very finely divided on its summit for the 
basal half, and the base is finely notched. It is also very closely allied to the following 
species [C. decipiens], from which it differs, however, in colour. The specimen figured 
is one from Bugaba. About a dozen examples were met with. That from Pantaleon 
has the scutellar patch larger and widened behind. 
29. Calopteron decipiens. (Tab. XI. fig. 7.) 
Nigrum ; prothoracis lateribus elytrisque miniatis, his tricostatis, pone medium paullo ampliatis, sutura basi 
nigricante, intervallis sat distincte irregulariter areolatis, Long. 8-11 millim. ¢ 9. 
Hab. Costa Rica, Rio Sucio (Rogers); Panama, Volcan de Chiriqui (Champion). 
This insect precisely resembles C. miniatum in size and colour; it is of course 
immediately distinguished if the three coste are noticed, the third interval being quite 
undivided longitudinally. It is also more expanded behind the middle, the thoracic 
carina is more finely divided near the base, and the transverse reticulation of the elytra 
is much more distinct. A large series of this species were taken by Mr. Champion. The 
single specimen from Costa Rica is a female, and was formerly confounded by me with 
C. miniatum.
