1888.] PHYTOPHAGOUS COLEOPTERA. 347 



anterior spots are placed exactly as in il/. 20-pynciata, but of those 

 placed below the middle the intermediate spot is wanting, so that 

 only two remain, and the last or apical spot is transverse, not elon- 

 gate as in the allied form ; the elytra are also more closely punctured 

 in the present species, and the legs are entirely fulvous. There are 

 more than twenty specimens before me, which all show the same 

 differences, as pointed out, and can be separated easily from M. 20- 

 punctata, 



Phytodecta flavipennis, n. sp. 



Broadly ovate, pale fulvous ; the terminal joints of the antennsc 

 and tlie legs black ; tliorax very minutely punctured on the disk, 

 strongly on the sides ; elytra finely punctate-striate, the interstices 

 scarcely visibly punctured. 



Length 2^ lines. 



Head distinctly but irregularly punctured ; antennae extending to 

 tlie base of the thorax, the terminal joints transversely shaped, black, 

 the lower four joints fulvous ; thorax three times wider than long, 

 narrowed in front, very minutely punctured, the sides deeply punc- 

 tate ; scutellnm fulvous ; elytra bread, sui)quadrate, the punctures 

 moderately deep, the interstices extremely finely punctured. 



The present species seems to differ fiom any other described P/it/~ 

 toclecta in several particulars: from most of them P.jiuvipfnms differs 

 in the fulvous upper and underside ; P. rufu, Kraatz, which al?o has 

 the underside red, is larger and the legs are described as red with the 

 exception of the knees. There are two specimens before me, which 

 show no difference, except that the colour iu one is paler, and that 

 the upper and lower margins of the breast are black, the latter is 

 deeply rugose-punctate. 



Phytodecta tredecimmaculata, n. sp. 



Broadly subquadrate, fulvous ; thorax with tliree black spots ; 

 scutellum black ; elytra strongly and closely punctured, the punctu- 

 ation irregular, each elytron with six black spots ; breast piceous. 



Length 3 lines. 



Head rather closely punctured on the vertex and on the clypeus. 

 Anteiinse entirely fulvous, extending to the base of the elytra. 

 Thorax three times broader than long, the sides evenly rounded, the 

 anterior margin broadly concave ; the disk finely and remotely, the 

 sides strongly and closely, punctured ; a large black spot is placed at 

 the middle, but does not extend to the base, a smaller one is situated 

 at each side ; scutellum black, very broad. Etytra subquadrate, 

 convex and short, very closely and distinctly punctured, the punctu- 

 ation not arranged in lines ; of the black spots, which are large, 

 one of oblique shape occupies the middle of the base, two, placed 

 transversely at, and two others, of which the inner one is sutural, 

 below the middle ; another sutural spot is placed at the extreme 

 apex. Below and the legs strongly punctured, the breast more or 

 less piceous.
