Hab. North America, Texas near the Eio Grande l 2 . — Mexico 3 , Matamoros 1 2 , 

 Orizaba (Salle), Yucatan ; Guatemala (Brit. Mus.). 



Three examples before me appear to be referable to this species. M. Thomson gives 

 " intento seneo-viridi-metallica " as the colour : two of the specimens are brownish- 

 aeneous ; the third, from Yucatan, has the elytra blue, and is also rather shorter in form 

 than the others. 



18. Chrysobothris trochilus. (Tab. III. fig. 11.) 



Nigro-purpurea, parum nitida ; capitis vertice, thoracis margine antico, macula marginali alteraque basi, laete 

 viridibus ; elytris subtiliter punctulatis, fovea basali impressa, macula humerali, fascia mediana (interne 

 dilatata) suturam baud attingente vittaque apicali prope marginem laete, aureo-viridibus, fortius punctatis. 



Long. 3 1 lin. 



Hab. Panama, Bugaba (Champion). — South America, Para (Brit. Mus.). 



The head is closely punctured ; the front of the face slightly impressed and tinted 

 with green. The thorax is broad, not very closely punctured, the punctures partially 

 connected by transverse striation, the punctures on the margin close and strong. The 

 scutellum is small, triangular, golden-green. The elytra have only one round fovea at 

 the base ; the punctuation is rather fine, the punctures well separated from each other, 

 and those on the green spots somewhat asperate. The posterior surface of the femora, 

 the middle of the sterna, and the margins of the metathoracic episterna and of the 

 abdomen are golden-green. The prosternum is closely and coarsely punctured. The 

 abdomen is bluish-green, with slight violet reflections ; the apical segment in the male 

 is deeply emarginate, the emargination as deep as wide, and rounded (Tab. III. 

 fig. 11a). 



19. Chrysobothris guatemalensis. (Tab. III. fig. 12.) 



Chrysobothris guatemalensis, Thorns. Typi Bupr. p. 80 (1878) 1 . 



Hab. Mexico, Yucatan (coll. Laferte, in Brit. Mus.), Totosinapan, Orizaba (Salle), 

 Vera Cruz, Jalapa, Almolonga (Hbge)\ Guatemala 1 (Salle), San Geiommo (Champion). 



In a considerable series of this species I have only seen two males, one from Mexico 

 and the other from Guatemala. They differ from the females in having the front of 

 the head, the greater part of the antennas, the prosternum, part of the mesosternum 

 and coxse, the anterior surface of the front and intermediate femora and tibiae, the 

 anterior surface of the posterior tibiae, and the tarsi, golden-green. The apical segment 

 of the abdomen is semicircularly emarginate in the male (Tab. III. fig. 12 a), slightly 

 tridentate in the female (fig. 12 b).
