 edulis. Enlarged 7 times. 



and quite dense. Head moderately convex, front finely and densely 

 punctured, slightly strigose, clypeus moderately semicircularly emargi- 

 nate. Thorax moderately convex, with parallel sides, basal angles 

 acute, lateral margins entire, dorsal surface coppery, evenly and densely 

 punctured, a slight oval depression near the basal angles, ventral 

 surface rather coarsely punctured laterally and posteriorly but densely 

 and finely punctured and rather strigose ante- 

 riorly, tip of prosternum constricted. Elytra 

 moderately and evenly punctured, with ba- 

 sal depressions, the tips obtuse, separately 

 rounded, the apical margin finely serrulate, 

 each elytron with three lemon-colored spots 

 arranged in a slight arc (fig. 6), anterior 

 spot the largest, winged on the outer side, 

 median spot next in size, slightly smaller, 

 oval, posterior spot smallest, about one-fourth 

 the size of the median, nearly oval. Ventral 

 surface of the abdomen evenly and moder- 

 ately punctured, quite pubescent, last (5th) 

 ventral segment obtusely rounded, nearly 

 subtruncate, with a strongly developed ser- 

 rate ridge near the posterior margin (fig. 6). 

 (?. — Resembles the female quite closely, but is much larger. Length, 

 9.5 mm. ; breadth, 4 mm. Thorax slightly narrowed in front, sides 

 slightly arcuate, lateral margins obliterated in front, tips of elytra more 

 rounding, spots on the elytra the same as in the female, last (5th) 

 ventral segment same, first joint of posterior tarsi not as long as next 

 two joints together. 



Type. — ? and d*, No. 11350, U. S. National Museum. 



The species is easily distinguished by the spots on the elytra, 

 which do not vary to any appreciable extent in the two speci- 

 mens examined. It falls between M. fulvoguttata Harr. and 

 M. intrnsa Horn, but differs from both in having the serrate 

 ridge near the posterior margin of the last (5th) ventral seg- 

 ment, and in the elytral spots. 



One female taken by Mr. E. A. Schwarz from pinyon (Pinus 

 ednlis) at Bright Angel Hotel (Grand Canyon P. O.), Arizona, 

 on July II, 1902. One male and one imperfect female reared 

 by the writer from larvae taken July 5, 1907, from the pupal 

 cells in the outer dead wood of the trunk of a dying pinyon at 

 Panguitch, Utah. One larva pupated July 20 and one July 25, 

 1907. One pupa transformed to a male adult about September 

 I, 1907. The larvae belong to the common Melanophila type 

 and were found curled up in the pupal cells.
