192 MB. MARTIN JACOBY ON NEW SPECIES [Mar. 4, 



nation near the apex. All these characters are, however, not 

 wanting in many species of Disonycha, and intermediate stages 

 frequently occur in which it is impossible to say to which genus 

 to refer the species. JSfephrica is therefore not a well-founded 

 genus, and it is impossible to fix the limit between this and 

 Disonycha. Nevertheless I have left the question in its present 

 state, and described all those species contained in my collection 

 in which the kidney-shaped eyes and other details peculiar to 

 von Harold's genus are well marked, so that there will be little 

 difficulty in recognizing these forms. 



Nepheica boliviana, sp. n. 



Pale flavous, the base of the head, the antennae, underside, and 

 legs black ; thorax impunctate ; elytra extremely minutely 

 punctured, yellowish white, a broad transverse band at the base 

 and another below the middle, not extending to the lateral nor 

 apical margins, metalHc green. 



Length 6 millim. 



Head piceous at the base, impunctate, the lower portion nearly 

 white, the carina distinct and broad ; antennae not extending to 

 the middle of the elytra, piceous, the basal joint flavous below ; 

 thorax twice as broad as long, the sides very feebly rounded, with 

 a narrow margin, the anterior angles truncate, the posterior 

 slightly truncate, the surface impunctate, yellowish white ; scu- 

 tellum black ; elytra nearly impunctate or with some extremely 

 minute punctures at the sides, metallic green, this colour not 

 quite extending to the lateral nor apical margins, and divided at 

 the middle by a narrow transverse flavous band ; below and the 

 legs black (in immature specimens stained with flavous). 



Hah. Bolivia. 



Allied to N. didyma lUig. and N. kirschi Har., but differing in 

 the design and colour of the elytra. In the above given description 

 I have taken the green colour for that of the ground, but in the 

 diagnosis the pale colour. 



Nephrica maculipennis, sp. n. (Plate XX, fig. 8.) 



Below black, as well as the antennae and legs ; head and thorax 

 flavous, the latter with five small black spots (4, 1 ) ; elytra closely 

 punctured, testaceous, the basal margin, the shoulders, a narrow 

 lateral stripe, connected with a broad transverse band below the 

 middle, and a round spot near the latter part, metallic green. 



Length 7 millim. 



Head sparingly punctured near the eyes, flavous, the extreme 

 vertex black ; carina acute, labrum and palpi black ; antennae 

 short, not extending to the middle of the elytra, black, the lower 

 three joints testaceovis below, third joint shorter than the fourth, 

 terminal joints slightly thickened ; thorax twice as broad as long, 

 the sides feebly rounded, the anterior angles oblique, the surface 

 impunctate, flavous, with four small piceous spots placed trans- 

 versely anteriorly, and another spot at the middle near the base ;
