CRYPTOSTOMA Latr. 

 C Dohrni n. sp.— Oblong, moderately elongate, subparallel, equally obtuse 

 at each end, color pale sanguineous, sides of body and elytra black, the latter 

 with a humeral spot and apex sanguineous, surface clothed with fine recumbent 

 pubescence the color of the surface. Antennse piceous, basal joint sanguineous 

 Head densely punctured, clypeus more sparsely. Thorax one-fourth wider than 

 long, sides moderately arcuate and gradually narrowed at apical third, hind 

 angles slightly prolonged posteriorly; disc convex, a slight depression within 

 each hind angle, a median flattening near the base and a very feeble, short, 

 oblique impression on each side of middle near the apex; surface sanguineous, 

 densely punctured and pubescent. Elytra oblong, slightly broader behind 

 the middle, striate, strise punctured, intervals flat, convex at base, densely 

 punctulate, color black, subopaque, humeri and apex sanguineous, surface 

 modeiately densely clothed with recumbent pubescence, black on the disc 

 red on the humeral and apical spaces. Body beneath densely punctured 

 and sparselj' pubescent; abdomen more finely and densely punctured; color 

 pale sanguineous metasternum and abdomen at the sides black. Length .60 

 inch; 15 mm. 



I have seen but one female of this very beautiful Eucnemide 

 which I owe to the great liberality of Dr. Dohrn of Stettin, by 

 whom it was sent with the assurance that it came from San Diego, 

 California, in a bottle of alcoholic specimens all the other speci- 

 mens being truly native to that locality. The bottle came from 

 Mr. Jas. Behrens. 



This species diifers notably in size and color from those de- 

 scribed by Bonvouloir, all of which come from tropical South 

 America. 



Cryptostoma has no antennal grooves. Epistoma narrowed at base, 

 rounded in front. Thorax with a single marginal line and the pleurae 

 triangular. The coxal plates are moderately dilated internally but 

 not suddenly. '1 he tarsi are slender and simple. The metasternal 

 epimera are concealed. 



The antennae of the two sexes differ in form and length, those of 

 the male being longer than half the body, the third joint with a 

 hook-like process at its base, the outer joints moderately long. The 

 female antennae attain the hind angles of the thorax and are stouter 

 but not dentate; third joint simple slightly obconical, fourth slightly 

 longer than the second and very little shorter than the fifth; joints 

 5 — 8 subequal slightly wider to the tip; ninth distinctly longer than 

 the eighth; tenth somewhat shorter ; eleventh still shorter and trun- 

 cate at tip. 



In an arrangement of our genera Cryptostoma must be placed near 

 SMzopliilus.
