SEEEICOENIA. 1 85 



apicem gradatim arcuatim attenuatis, haud crebre punctatis, tricostatis, costa suturali fere recta (basi 

 abbreviata), costa secunda (basi longe abbreviata) medio curvata, tertia ad medium solum distincta. 

 Long. 4-6 lin. 



Bab. Mexico, Temax in Northern Yucatan (Gaumer). 



This species belongs to the C. multistigmosa group, and is most nearly allied to 

 C. distincta, Lap. & Gory, but is rather shorter, more brassy in colour, and has the 

 sides of the thorax rounded. The head has two small smooth spots in front. The 

 thorax is short and broad, and has the sides unusually rounded ; the punctuation on 

 the disc is fine, and the punctures are not very close together ; there is a very slight 

 trace of a median impression. The elytra, as compared with other species in this group, 

 are rather short ; they have the punctures very distinct and slightly separated from each 

 other; there is a small brassy impression interrupting the basal part of the second 

 costa, another (more transverse) at the apex of the third costa, and a third at some 

 distance from the apex, between the first and second costse ; the first costa is recti- 

 linear, a little more separated from the suture at the apex than at the middle ; the 

 second costa, which commences a little before the middle of the elytron, is curved at its 

 middle to avoid the brassy spot ; the third costa is short, turns down anteriorly a little 

 below the shoulder, and terminates posteriorly in the impression. The prosternum in 

 the male is closely punctured, with a smooth median line ; in the female it is smooth, 

 with a few punctures at the sides. The abdomen in the male has a shallow median 

 channel for its whole length, the terminal segment serrate at the sides, with a rather 

 wide but shallow trapezoidal excision at the apex ; in the female there is a very small 

 semicircular emargination at the apex, the angles of the emargination very acute. The 

 anterior femora have the large triangular tooth denticulate on the outer edge. The 

 anterior tibiae are curved ; enlarged at the apex in the male, simple in the female. 



Chrysobothris distincta (p. 45). 



To the Mexican localities given, add : — Venta de Zopilote and Amula in Guerrero 

 (H. H. Smith). 



Chrysobothris multistigmosa (p. 46). 



To the Mexican localities given, add :— Acaguizotla in Guerrero 1500 feet (H. H. 

 Smith), Temax in Northern Yucatan (Gaumer). 



Chrysobothris lateralis (p. 47). 



According to Dr. Horn this species is C. debilis, the type specimen of which does not 

 show the red sides to the thorax. This is so conspicuous in all the examples I had seen 

 that I could not credit Leconte omitting to notice it. The specimens received from 

 Mr. Morrison with the name C. debilis are, according to Dr. Horn, C. lixa, Horn (Trans. 

 Am. Ent. Soc. xiii. p. 101), a species occurring in Texas and Arizona.
