xv - l Baker: The Malay mi Machaerotmas 71 



reticulate within, the lateral margins high and thin ; spine with 

 its point about 1 millimeter above apex of tegmina. 



Male. — Length to end of abdomen, 3 millimeters; to end of 

 tegmina, 4.5; to end of spine, 5.5. 



Colors deeper than in the female, the pronotum almost piceous. 

 The spine is more or less minutely dotted, and the lateral yellow 

 marks on body of scutellum are abbreviated posteriorly. 



This is a common species at Los Baiios and on Mount Ma- 

 quiling, both localities in Laguna Province, Luzon Island, Phil- 

 ippine Islands. 



Machaerota luzonensis Schmidt. 



Macfuerota luzonensis Schmidt, Ent. Zeitg. Stettin 68 (1907) 189. 



Female. — Length to end of abdomen, 4 millimeters; to ends 

 of tegmina, 6; to end of spine, 7. 



Color stramineous; spine, and scutellum caudad, pale reddish 

 brown; legs yellowish. Frons yellowish, with eight horizontal 

 piceous bands on either side, and with no median dark color 

 except above; scutellum with an indistinct, median piceous 

 stripe; posterior yellow border of body of scutellum broader 

 below, the intramarginal, deeply depressed line piceous; the 

 curved yellowish marks on sides of body of scutellum very in- 

 distinct; a few dark dots on borders of scutellar groove. 

 Abdomen stramineous, ovipositor piceous. 



Frons nearly smooth, indistinctly shagreened, the lower bor- 

 der, with clypeus, more coarsely sculptured; face almost entire- 

 ly without appressed white pubescence. Pronotum coarsely 

 reticulate-punctate except near anterior margin, but the retic- 

 ulations are not sharp; the four slightly depressed oblique arese 

 near fore margin short, minutely roughened, and piceous; the 

 median ridge sharp and high. Reticulate character of punc- 

 turation less evident on body of scutellum; spine strongly curved 

 at base, its point a millimeter above the apex of tegmina. 



In all of the Philippine material before me, there appear to 

 be but two specimens that approximately fit the original de- 

 scription of Schmidt's species. These are from Davao, Min- 

 danao Island, Philippine Islands. 



Machasrota ensifera Burm. 



MachsBrota ensifera Burmeister, Handb. Ent. 2 ' (1835) 128. 



The disposition of colors on pronotum in longitudinal stripes 

 clearly marks this species in all of its various light and dark 

 phases. The common form in Luzon is pale in color, but very
