38 SERBICOKNIA. 



11. Chrysobothris nausicaa. 



Chrysobothris nausicaa, Thorns. Typi Bupr., Append., i. p. 45 (1879) . 

 Hob. Mexico 1 , Orizaba (Salle); Guatemala (Scherzer); Panama (Boucard). 



The specimens which I identify with C. nausicaa measure only 8 millim. in length, 

 instead of 9 millim. as given by M. Thomson. This insect appears to me to be scarcely 

 distinct from C. cayennensis (Gmel.), a species occurring in Venezuela and on the 

 Amazons. 



12. Chrysobothris melazona. 



Chrysobothris melazona, Chevr. Col. Mex. Cent. ii. fasc. 5, no. 104 (1835) \ 



Chrysobothris nigrofasciata, Lap. & Gory, Mon. ii. p. 21, t. 3. f. 32 2 (nee Lee. Trans. Am. Phil. 

 Soc. 2n*d ser. xi. p. 240). 

 Bab. Mexico 1 2 , Cordova, Orizaba, Puebla, Vera Cruz (Salle), Jalapa (Hoge) ; British 

 Honduras, E. Hondo (Blancaneaux) ; Guatemala, Coban, Lanquin, Rio Naranjo 

 450 feet (Champion). 



This species varies from 3-J-5-J lin. in length. One example from Orizaba is golden- 

 coppery ; another from Jalapa has the elytra blue. 



13. Chrysobothris convexiuscula. (Tab. III. fig. 7.) 



Lsete viridis, nitida ; elytris fasciis tribus sat latis cyaneo-nigris ornatis, fascia basali ad suturam interrupta ; 



abdominis segmento ultimo fere lsevi, cyaneo-nigro. 

 Long. 4| lin. 



Hal. Nicaragua, Chontales (Belt). — Colombia (Brit. Mus.). 



This species differs from C. melazona in having the middle bands of the elytra united 

 at and somewhat extended on the suture ; the posterior bands are also united at the 

 suture, and the suture itself narrowly edged with blue-black at the apex. The abdomen 

 has a series of blackish spots on each side, and the apical segment is entirely blue-black, 

 and much less punctured than in C. melazona; the apical margin of the terminal 

 segment is sinuous, with an acute tooth at each angle (Tab. III. fig. 7 a). 



14. Chrysobothris juncta. (Tab. III. fig. 8.) 



Elongata, sat convexa, azurea, crebre evidenter punctata : fronte laete aureo-viridi ; elytris fasciis tribus sat 



latis cyaneo-nigris, fascia basali ad suturam interrupta. 

 Long. 3^ lin. 



Hab. Mexico, El Cameron (Salle), Jalapa (Hoge).

 Although this species is somewhat intermediate in its appearance between C. melazona 



and C. cupreipes, it is really, on account of its convexity and the straight sides to the 



thorax, allied to C. analis, Lee. The head is flattened in front, and has a slight, short 



frontal ridge, which is divided in the middle. The thorax is very convex, parallel at 



the sides, rather closely and very distinctly punctured. The elytra have a deep fovea
