2')8 Mr. C. 0. Waterhouse on Cohoptera 



This species is very near P. velasco, L. & G., but that has 

 a rather more angixlated thorax, &c. It is possible that 

 velasco ami montezuma, L. & G., may be sexes of the same 

 species, but there is uot material at hand to enable ms to 

 decide. 



Folycesta varieyata, sp. n. 



Elonorate, brownish coppery, slightly shining, gently con- 

 vex. Thorax obtusely angular at the sides, broadest just 

 behind the middle, obliquely narrowed in front and towards 

 the base, the lateral angle rounded, the posterior angles very 

 slightly projecting and acute. Disk with a distinct but 

 shallow longitudinal impression, narrow in front, broader at 

 the base. The punctures on the disk are moderately strong, 

 not close together; at the sides they are smaller, crowded 

 together, leaving a few irregular raised lines. Base smooth 

 in the middle, blackish. Elytra gently convex, variegated 

 with Eeueous blaok spots and marks, each elytron with a fine 

 costa next the suture, extending nearly to the apex ; the 

 second and fourth costse very distinct, wide at the base, 

 becoming gradually narrower to the apex; the third costa is 

 represented by a slightly raised line in the basal part of the 

 interval between the second and fourth costae. There are 

 lines of moderately strong punctures, not very equal in size 

 and mixed with much smaller ones. The spines at the apex 

 are rather strong and acute. The punctures on the middle 

 of the abdomen are moderately strong, not very close 

 together, horseshoe-shaped ; at the sides the punctuation is 

 close and rugose; the apical segment is closely punctured 

 and has a fine raised median line at the apex. 



Lung. 17 mm. 



Hub. Mexico [Hoge) ; from the Godman and Salvin 

 collection. 



In general appearance this species much resembles 

 P. tonkinea, Fairm., but that has the thorax less angular at 

 the sides, and the first costa of the elytra is abbreviated and 

 thick, in this species it is tine and complete, 



Acmaodera luzonica, Nonfr. 



Acmcsodera luzonica, Nonfr., Berl. ent. Zeit. xl. p. 302. 



Herr Nonfried describes this species as bronzy green. All 

 the British Museum specimens from Luzon &c. which 

 appear to belong to this species are nearly black, a single 

 example from Siam being somewhat purple-violet. It is 

 confounded in most collections with A. stictipennis, L. & G.,
