GALEEUCELLA. 491 



5. Galerucella fusco-maculata. (Tab. xxvili. fig. 2.) 



Elongate, parallel, finely pubescent ; obscure pale testaceous, opaque ; thorax with three obscure fuscous spots ; 



elytra very finely punctured and coriaceous, pubescent, each with three more or less distinct longitudinal, 



partly interrupted, fuscous bands. 

 Var. Elytra almost entirely fuscous. 

 Length 2-2| lines.

 (Blancaneaux) ; Guatemala, Las Mercedes, Zapote, San Geronimo, Cubilguitz, Chiacam,

If I refer rightly the numerous specimens from the above localities to one species, 

 G. fusco-maculata is subject to great variation in regard to size and general colour. I 

 cannot find any published description agreeing with this species, although it may be 

 one of those described by Leconte. In the insect before me the antennae are less than 

 half the length of the body, fuscous or lighter ; the thorax is short and transverse, with 

 rounded sides and oblique posterior angles, the surface depressed at the sides and 

 near the base, finely granulate and pubescent, with or without fuscous markings ; the 

 elytra are more distinctly punctured than the thorax, pubescent and entirely opaque, 

 and may be described as pale or darker fuscous, each having three narrow whitish lines 

 which divide the ground-colour longitudinally, the ground-colour is often broken up 

 into longitudinal spots of equal width, which sometimes, as well as the lighter lines, are 

 very indistinct ; the legs are either testaceous or fuscous. Some specimens from British 

 Honduras are much narrower in shape than others from Guatemala and the State of 

 Panama, but, in spite of this difference and that of colour, I cannot find sufficient marks 

 of distinction to separate these forms. A specimen from Cerro de Plumas is figured. 



6. Galerucella marmorata. (Tab. XXVHI. fig. 3.) 



Obscure fuscous or fulvous below ; clypeus and legs testaceous ; femora with a black spot ; thorax reddish- 

 fulvous, with three black spots ; elytra finely pubescent and punctured, fuscous, each with two or three 

 pale narrow longitudinal lines. 



Length 3 lines. 



Eab. Mexico (Salle) ; Guatemala, Panima in Vera Paz (Champion). 



Larger and more robust than G. fusco-maculata, but almost identical in coloration ; 

 the head is covered with thin yellowish pubescence; the antennae are black, more 

 robust, and the terminal joints are slightly thickened; the thorax is shaped as in 

 G. fusco-maculata, but of a reddish colour, with three large round black spots occupy- 

 ing nearly the entire disc, the surface covered with fine silky yellow hairs, the usual 

 depressions are present, but the punctuation is scarcely visible ; the elytra are very 

 finely (in one specimen) or more distinctly rugosely-punctured, covered with greyish 

 hairs, and each marked with three broad longitudinal fuscous bands, the sutural one 

 being interrupted before and below the middle by an obscure fulvous spot, a similarly
