242 THE ENTOMOLOGIST. 



Type, one example, Chihuahua, Mexico (Wickham) (coll. 

 Bowditch). 



Front with a few fine punctures and a small frontal fovea, neck 

 slightly constricted behind the eyes, thorax tubular, moderately con- 

 stricted near the base, a few very fine punctures near the front, 

 scutel rufous ; elytra deeply, coarsely quadrate punctate, arranged in 

 regular striae, the punctures becoming smaller behind, where the 

 intervals become costulate ; the femora are rather swollen and then 

 suddenly constricted near the end ; allied to the small similarly 

 coloured forms like amabilis, Jac, but easily distinguished from all 

 by the black legs and antennae, with entirely rufous body. 



Crioceris chiriquensis, nov. sp. (Jac. in lift.). 



Uniformly bright metallic green, with labrum and joints 5-11 of 

 antennae, blue-black and dull, underside more or less bluish ; elytra 

 finely and nearly regularly punctulate striate, the entire surface 

 minutely alutaceous, and with irregular fine wrinkles, giving a semi- 

 dull appearance. Length 11 mm. 



Type Chiriqui, eight examples (coll. Bowditch). 



Size and form of nullicedo, Lac, and its allies ; head with a deep 

 longitudinal groove in the vertex, with fine punctures on either side, 

 surface alutaceous, joints three and four of antennae equal, the latter 

 reaching beyond the middle of the -body, thorax strongly constricted 

 at middle, vaguely quadrifoveate on the disk (the foveae placed in a 

 square), the surface alutaceous, and finely punctate and obsoletely 

 strigose near the anterior angles and along the sides ; elytra nearly 

 parallel, faintly punctulate striate, almost obsolete in places in some 

 specimens, a faint lateral impression slightly one side of the middle, 

 similar to nullicedo, Lac, and its allies ; as compared with nullicedo, 

 the surface of chiriquensis is more distinctly alutaceous and wrinkled ; 

 there is no trace of any transverse coloured band ; the curving of 

 the tibiae is about the same in both ; there are other minor differences 

 of punctuation ; nitida, Lac, has a sparsely but distinctly punctate 

 thorax. 



Crioceris tumida, nov. sp. 



Head rufous, elongate, clypeus swollen, sparingly punctured and 

 pubescent, antennae with first 4 joints short, 3 and 4 equal, remainder 

 broadened (slightly more so at tip) and closely articulated, vertex 

 punctate, deeply grooved, neck strongly constricted ; thorax rufous 

 yellow, elongate, faintly transversely depressed near base, strongly 

 compressed laterally a trifle behind the middle, with a double line of 

 very fine punctures down the middle, vanishing behind in a vague 

 depression, and with a faintly marked fovea in either side before the 

 middle ; scutellum hairy ; elytra much wider than the thorax, 

 squarely truncate, with the scutellar region raised into a peaked 

 hump ; general colour yellow, with a more or less interrupted rufous 

 band behind the middle, and the apex and shoulders also indefinitely 

 rufous, the surface polished and shining, as if varnished, with a few 

 scattered deep foveate punctures between the shoulders and scutellar 

 region ; only one or two on the hump, which is limited behind by a
