Hah. Panama, Chiriqui (Trbtsch). 



This species is allied to H. octopunctata, or perhaps more nearly to H. batesi, Saund., 

 but is a shorter and broader insect. The upper part of the thorax is dark brownish- 

 purple verging into coppery-red near the front angles ; the green of the lateral margin 

 is continued a little way round the anterior angles. The elytra are rather flat, and 

 have little trace of striae ; each elytron has the following green marks : — a triangular 

 spot below the humeral callus, with the green continued along the margin for some 

 distance ; a round spot at the base ; an oblique oval spot near the suture at one quarter 

 from the base ; a transverse spot in the middle ; two spots a little less than halfway 

 between middle spot and the apex ; and a short stripe at the apex close to the suture. 

 The marginal teeth of the elytra are very strong ; the one immediately before the apex 

 is acute and directed slightly outwards, and the sutural angle itself is very acute and 

 turned obliquely inwards — in this respect H. laticollis differs from any other members 

 of the genus known to me. 



3 (a). Halecia suffusa. 



Brunneo-cuprea, nitida, pallide flavo-griseo-pulverosa ; capite rufo-cupreo, sat crebre punctulato, medio leviter 

 impresso ; thorace cupreo, nitido, antice angustato, disco (linea mediana excepta) maculaque laterali ante 

 medium viridi-cyaneis, angulis posticis sat acutis, divergentibus ; elytris brunneo-cupreis, tenuiter punc- 

 tato-striatis, cyaneo-maculatis ; abdomine aeruginoso-tincto ; tarsis caeruleis.

Hab. Panama, David in Chiriqui (Champion). 



This species has the form of H. beltii (Tab. I. fig. 6), but is a trifle narrower, and has 

 the elytra more acuminate at the apex. It differs from H. cyaneo-notata, Saund., 

 which it still more nearly resembles, in having the posterior angles of the thorax acute 

 and diverging, and in having the elytra less prolonged at the apex. Each elytron has 

 the following dark blue spots : — one on the humeral callus ; one near the base and 

 close to the suture ; three spots, one below the other, in a line down the middle of the 

 elytron, the hind one small and transverse; and an elongate spot near the apex. The 

 margins of the elytra are not dentate. 



3 (b). Halecia pulverulenta. 



Supra senea, subtus aeruginosa, nitida, flavo-pulverulenta : capite crebre fortiter punctato, antice canaliculato ; 



thorace antice sat angustato, punctato ; elytris punctato- striatis, marginibus subtus tarsisque caeruleis.
