240 THE ENTOMOLOGIST. 



Two examples sent by Messrs. Staudinger & Bang Haas with 

 the foregoing manuscript name, and three others among the unnamed 

 Jacoby material apparently from the same place. Exceedingly close 

 to similis, Lac, the most obvious difference being the black labrum, 

 the other differences being opinionative ; the thorax of callangaensis 

 is perhaps a trifle more elongate and less compressed, the punctua- 

 tion is similar, the elytra of callangaensis are a trifle stouter, and the 

 punctuation somewhat stronger ; but these differences are slight, 

 and more of degree than anything definite ; the black labrum is the 

 same in four of my five examples, and rather dubious in the other. 



The above description will serve to draw attention to the 

 two forms until they have further study. 



Lema marcapatensis, nov. sp. (Jac. in litt.). 

 Head black, antennae black, becoming fuscous at tip, thorax 

 rufous, shining, scutellum black, elytra, cyaneous blue or green, with 

 two small dots on the basal margin, a curved fascia behind the 

 middle, the apex broadly and the lateral margin narrowly, yellow ; 

 body beneath and part of the first abdominal segment black, 

 remainder of abdomen yellow, feet black with trochanters, and an 

 elongate spot on the underside of the femora yellow, tarsi fuscous. 

 Length 6| mm. 



Type, Marcapata, Peru (coll. Bowditch). 



Head with usual frontal puncture, transversely depressed behind 

 the vertex, the extreme neck rufous, thorax rather strongly con- 

 stricted and depressed behind, shining, impunctate, elytra with 

 humeral and basal depressions fairly well marked, the elytral punc- 

 tures becoming obsolete behind, and the intervals correspondingly 

 costiform ; the fulvous band is placed behind the middle, and narrow, 

 of equal width and convex in front, the front edge attaining the 

 middle of the elytra ; the anterior edges of the apical yellow spot 

 are slightly oblique or almost straight, the small yellow dot at the 

 base is doubtless often absent, and probably the middle band varies 

 a good deal; beneath, the black colour of the body is extended into 

 the first segment of the abdomen by a lunate spot on each side, 

 occupying about half the space ; the elongate femoral spots are 

 particularly well developed on the four posterior legs. 



The above description is made on the basis of the elytra 

 being cyaneous with yellow bands, but it could equally well be 

 termed yellow with cyaneous markings. 



Distributed by Messrs. Staudinger & Bang Haas with the 

 above manuscript name; very close to violaceo-margmata, 

 Clark. 



Lema rufoc'incta, nov. sp. 



Violaceous, with head, thorax, femora, body beneath, and elytral 

 margins (except part of the suture) yellow, antennas (except the first 

 joint), tibiae, and tarsi black. Length 8 mm. 



Type, one example, Playa Vicente, Mexico (coll. Bowditch). 

 Head with smooth, polished vertex, and deep side grooves, not
