408 Mr. J. S. Baly on new G mera and Species of GallerucicUe. 



Mas. (Edeagus apice lanceolato-ovatus, lateribus ad apicem bi- 

 sinuatis, apice ipso vix producto, truncato, recurvato. 



Fcem. Abdominis segmentum anale utrinque foveolaturr, apice angu- 

 lato sat profunde inciso ; thorace toto flavo ; antennis totis, femori- 

 bus dorso, tibiis tarsisque nigris. 



Var. A. (fcem.). Elytris obscure nigro-purpureis. 



Long. 5-6 lin. 



Hah. Nauta, Upper Amazons. 



This species, although of larger size and brighter coloration, 

 very closely resembles D. laticolle, more especially in the form 

 and punctuation of the thorax; the ? maybe known by the 

 linear notch at the apex of the abdomen, the $ by the paler legs 

 and the brighter colour of the elytra. Front with a large semi- 

 ovate rugulose depression ; vertex nitidous. 



I possess three specimens of this species, one^, two $ . 



Dire 'ma columbicum. 



I), elongation, parallelum, sordide flavum, nitidum, vertice, fronte 

 (hoc maculam flavam includente), antennis, femoribus dorso, tibiis 

 tarsisque nigris ; thorace longitudine duplo latiore, lateribus ante 

 medium modice ampliatis, disco modice sed late transversim ex- 

 cavato, crebre punctato, pube adpressa dense vestito, utrinque 

 macula ovata nigra ovnato ; elytris metallico-viridibus, subopaeis, 

 pube subdepressa brevi vestitis, margine suturaque flavis. 



Fcem. Abdominis segmentum anale apice obtuse angulation, breviter 

 incisum. 



Long. o" lin. 



Hub. Bogota. 



I only know a single specimen of the present species (a ? ). 

 It may be easily separated from all its congeners by the peculiar 

 form of the thorax ; this part is less transverse, being only about 

 twice as broad as long; its sides in front are less dilated, and 

 the upper surface much less deeply excavated; the hinder angles 

 are produced into an obtuse tooth. The elytra are much broader 

 than the thorax, somewhat depressed above. Face long, clothed 

 with pale hairs; vertex and front black, the latter nearly plane, 

 marked in the centre with a transverse yellow patch. 



Dircema latum. 



D. elongatum, parallelum, convexum, dorso subdepressum, sordide 

 fusco-flavum, nitidum, vertice antennisque nigris, illo rugoso, bis 

 basi et apice flavis ; thorace longitudine vix duplo latiore, lateribus 

 ante medium modice ampliatis, disco late transversim excavato, 

 crebre rugoso, pube brevi adpressa dense vestito, sordide flavo, 

 utrinque plaga magna nigra ornato; elytris rugoso-granulosis, 

 pube adpressa brevi i'usco-fulva dense vestitis, viridi-aeneis, sutura
