the face lialf-way between the insertion of the antennai and the auteiior ocellus. 

 This is a rather slight longitudinal ridge. Half way between the upper edge of 

 this ridge and the anterior ocellus there is a transverse arch extending nearly 

 from eye to eye and forming practically three sides of an octagon. Above this 

 ridge the tegument is practically reticulated as far as the vertex, temples and 

 cheeks The distance between the posterior ocelli is about one and one-half 

 times as great as the distance between the posterior ocelli and the anterior ocel- 

 lus. This latter distance being practically equal to the distance between the pos- 

 terior ocelli and the nearest eye margin. 



The dorsum of the thorax reticulated in much the same way as the dorsum of 

 the head. The reticulations on the dorsulum, scutellum and metanotum some- 

 what coarser than on the pronotum. The lateral angles of the metathorax are 

 acute, slightly curved and directed backward, downward and outward. 



The first abdominal segment with a very shallow median impression extending 

 nearly to the posterior margin along the middle of the first dorsal segment, the 

 punctures are separated in much the same way as in the preceding species. The 

 basal half of the second dorsal abdominal segment is of a rather rugulose charac- 

 ter, the punctures adjoining each other. On the posterior half the punctures are 

 separated. The spaces between them, however, are not more than a puncture's 

 width apart. The apical dorsal abdominal segment is punctured in much the 

 same way as the preceding segment. Laterally the abdominal segments aie 

 rather reticulated like the dorsum of the head and thorax. The sulcus of the 

 apical dorsal segment has a series of pits irregularly separated (when separated), 

 mostly confluent. The lateral margin and the posterior margin with much the 

 same pattern as in kahli. 



Color. — Green. 



Legs and venter of abdomen with bluish reflections. 



Type. — University of Kansas. 



Type locality. — Hamilton Co., Kansas, 3350 ft. 



One specimen, collected by F. H. Snow. 



Clirysis (Tetraclirysis) snowi n. sp. 



Related to ca'ridans. Readily distinguished by the white pubes- 

 cence in the basin of the face. 



11 mm. — Head. — Scarcely as in its ally; frontal excavation distinctly margined 

 above, covered with adjoining shallow punctures or rather somewhat rounded 

 indentations, these are so small that it would take about six to ten of them in a 

 line to span transversely the first joint of the flagellum, a triangular area with 

 its base at the superior boundary of the frontal excavation, and its apex on the 

 median line about half way between the anterior ocellus and the interspace be- 

 tween the insertion of the antennse has larger nearly circular depressions, the 

 frontal depression has the sculpture of the lower two-thirds obscured in certain 

 lights; vertex and occiput about twice as coarsely punctured as the triangular 

 area of the frontal depression. 



Thorax. — Somewhat more coarsely punctured .than the vertex. 



Abdomen. — More distinctly punctured than the dorsulum, but its punctures not 

 larger, nor as close together; pits of the apical dorsal segment confluent, forming
