in depth towards the apex, interspaces also minutely punctate, and 

 from below the base to the apex closely and finely transversely 

 wrinkled ; there is also an indistinct transverse depression below the 

 base ; the ground-colour is a dark chestnut- brown ; the disk, however, 

 is almost entirely occupied by a broad piceous band, commencing 

 below the base and extending to the apex, leaving only the sutural 

 and lateral margins brown. Underside and legs of the same colour, 

 abdominal segments margined with piceous, claws entirely of that 

 colour. The hinder femora very short. 



This interesting Lema, of which I have at present only one speci- 

 men before me, will be easily recognized by the curiously shaped 

 antennae and the sculpture of the elytra, although it is doubtless 

 subject to variation in colouring. 



Genus Urodera, Lac. 



4. Urodera godmani, sp. nov. 



Oblong-ovate, black, shining, beneath closely pubescent. Head 

 and thorax finely punctured. Elytra finely punctate-striate, black, 

 a transverse band at the base, not touching the suture and the apex, 

 rufous. ' 



Length 3-4 lines. 



Hab. Duefias, Capetillo (Guatemala). 



Head with an obsolete transverse semicrescent groove between the 

 eyes, distinctly but finely punctured. Antenna? short, black, the 

 second and third joints rufous, dentate from the commencement of 

 the fourth joint. Thorax transversely convex, about twice as broad 

 as long, its sides moderately rounded and greatly deflexed anteriorly, 

 the lateral margins flattened and divided from the convex part by 

 an oblique depression ; the flattened portion distinctly punctured 

 and subrugose, rest of the surface very finely punctate, posterior 

 margin oblique at each side, its middle lobe straight. Scutellum 

 with a few extremely minute punctures. Elytra not wider at the 

 base than the thorax ; each elytron with nine rows of punctures and 

 a short double row near the suture black ; a transverse band, sinuate 

 below the humeral callus and interrupted at a little distance from 

 the suture, and an oblong apical spot rufous ; the latter spot does 

 not quite touch the lateral margin or the suture. Underside 

 closely covered with greyish pubescence ; anterior legs longitudinally 

 sulcate at their inside ; prosternum very narrow. 



The punctured head and thorax will distinguish this speecis from 

 others similarly marked, while the design of the elytra separates it 

 from U. chevrolatii, to which it bears some resemblance ; the thorax 

 is also much more transverse than in the latter species. None of 

 the specimens before me differ except in size from each other. 



Genus Cheamys, Knoch. 

 5. Chlamys sex-tuberculata, sp. nov. 



Quadrate-ovate. Head, body below, and legs fulvous, spotted with 

 violaceous ; above violaceous blue, clothed with white pubescence,
