Head longer than the pronotum, which is not more than 

 one half as long as it is wide; pronotum concolorous. .2 



2. Head about three times as long as the pronotum, which is 



four times as wide as it is long; hemelytral markings 

 confluent in longitudinal bands; hind wings absent (all 



Europe) C. coleoptrata Fab. 



Head very slightly longer than the pronotum, which is 

 about twice as wide as it is long ; hemelytral markings 

 not confluent ; hind wings present 3 



3. Size smaller, length about 6 mm. (all Europe). 



C. honsdorffi Sahlbg. 



Size larger, length 7.5 to 8.3 mm. ; American species 



(Minnesota and Dakota) C. americana n. sp. 



Cymatia americana, n. sp. 



Near C. honsdorffi Sahlbg., but differing as stated above. 

 General color above dark olive-green in living individuals, 

 marked with black ; in pinned specimens the green rapidly 

 fades to yellowish brown. Length 7.4-8.3 mm. ; width of pro- 

 notum 2.0-2.5 mm. ; width across hemelytra 2.6-3.0 mm. 



Head green, broadly infuscated behind, and with two large 

 brown spots on the hind margin of the vertex; head slightly 

 longer than the pronotum and about twice as wide as it is long. 

 Inner margins of the eyes straight, diverging anteriorly ; synth- 

 lipsis one fifth to one fourth narrower than the anterior margin 

 of the vertex ; vertex with several concolorous punctures an- 

 teriorly. Front coarsely punctured each side, and with long 

 whitish pubescence which is erect in living specimens. 



Pronotum subshining, about twice as wide as it is long, dark 

 olive-green to olive-brown in life, the margin narrowly blackish, 

 the lateral submargin very lightly impressed. Median keel 

 becoming obsolete on the posterior third of the disk ; anterior 

 margin of pronotum lightly emarginate, posterior margin very 

 slightly sinuate. Disk of pronotum with several very fine 

 transverse scratch-like impressions, interrupted by the median 

 keel, sordetimes absent. Pronotumi very minutely rastrate 

 (it requires a compound microscope to resolve the rastrations). 



Hemelytra' olive-green, marked with black. Clavus rastrate- 

 rugulose, with oblique black lineations which are usually 

 heaviest near its base ; the lines somewhat forked and broken, 

 not reaching the inner angle, more irregular and sometimes 

 confluent on the apical part. Corium sparsely and irregularly 

 punctate with black, and with numerous irregular blackish 

 maculae which are commonly heaviest near the apex of the 

 clavus and which tend to form two or three indefinite longi- 

 tudinal series. Embolium whitish, externally margined with
