than half the second, the lower aj)ical angle prolonged in a })oint be- 

 neath the fourth joint, last joint oval, acute, shorter than the third. 



Thoracic segments short, each with two dorsal plications. 



Abdominal segments from the first to fifth formed of three plicae, 

 one of which is narrower on the dorsum and pyriform in outline 

 beneath, the other two cuneiform, broader on the dorsum and gradu- 

 ally more acute beneath. At the ventral end of the larger are some- 

 what oval folds, in which the stigmata are placed. Last three seg- 

 ments quite smooth, not plicate, the terminal segment divided into 

 two unequal parts by a distinct suture, and near the apex a deep 

 arcuate impression separating a pseudo-pygidium. Anal opening 

 transverse. 



Legs widely separated at base, the posterior pair longer, hairy 

 above and with spinous hairs beneath. PI. iii, figs. 15-16. 



Cox^ long and rather slender, supporting a trochanter, the femur 

 short and stout, the tibise oval, the front tibia Avith a single long claw, 

 the middle with a short claw, the posterior Avithout claAv. 



Stigmata on each side nine, the first in the prothoracic segment, 

 the others in the lower side of oval plicae in the first eight abdominal 

 segments. 



Surface. — The thoracic segments are comparatively smooth, a 

 few indistinct scattered granules and with moderately long erect 

 hairs. The abdominal segments 1-8 are moderately densely granu- 

 late, each granule with a very short erect hair. The last three seg- 

 ments of the abdomen are smooth and shining, a few scattered long 

 hairs. The terminal segment is, however, more punctate and rugu- 

 lose near the tip, the hairs more numerous. The underside of the 

 body has scattered hairs.

This larva does not dififei' essentially from that of the European 

 Meloloufha vulgaris as figured by Ratzeburg (Forst. Insecten pi. iii, 

 fiig. 1, et se(j.). As in that species the thoracic region is the wider, 

 from this the body is gradually narrower to the fourth abdominal 

 segment, then gradually wider to the last segment. 



For the specimen described and figured I am indebted to Mr. J. 

 J. Rivers, of Berkeley, California.
