latter in the male projecting beyond the apices of the elytra ; the thorax in the male 

 is also less transverse, and the sixth joint of the antennae is longer and thicker than the 

 corresponding joint in the female ; in all other respects the specimens agree. 



8. Allochroma sexsignatum. (Tab. XXV. fig. 9.) 



Allochroma sexsignatum, Clark, Cat. Halticidse, p. 193 \ 



Hab. British Honduras, Belize (Blancaneaux). — Brazil 1 . 



The single specimen obtained by M. Blancaneaux agrees in every particular with the 

 type contained in the collection of Mr. Baly ; the only difference to be noticed is the 

 rufous (not flavous) colour of the thorax and the generally brighter colour of the insect 

 from British Honduras, attributable no doubt to its comparatively recent capture. 



9. Allochroma chiriquense. (Tab. XXV. fig. 10.) 



Pale fulvous, glabrous ; first six joints of the antenna piceous ; thorax and elytra testaceous, the former 

 remotely punctured, the latter deeply punctate-striate, the interstices longitudinally costate, a square- 

 shaped spot at the base and another below the middle fulvous, margined with piceous. 



Length 3 lines. 



Head distinctly but not very closely punctured ; the clypeus deflexed anteriorly ; penultimate joint of the palpi 

 transversely dilated, piceous ; antennae slender, the third joint much longer than the fourth and the 

 longest, the four terminal joints fulvous and shorter than the rest, the others piceous ; thorax transversely 

 quadrate, the sides straight at the base, rounded in front of the middle, the disc with three deep im- 

 pressions placed transversely near the base, the interspaces with a few punctures, the sides more closely 

 punctured ; elytra flattened, broadly subquadrate, regularly and deeply punctate-striate, the apices nearly 

 impunctate, the interstices strongly longitudinally costate, especially near the sides, where they form 

 acutely raised ridges, at the base a square-shaped fulvous spot extends to nearly the middle of each 

 elytron, while a similar rather smaller spot is placed immediately below the middle, both are surrounded 

 with a piceous margin, the rest of the elytra is of a pale testaceous colour, with the exception of the 

 sutural and extreme lateral margins which are fulvous ; underside and legs pale fulvous. 



Hab. Panama, Volcan de Chiriqui (Champion). 

 A single specimen. 



10. Allochroma godmani. (Tab. XXV. figg. 12, 13.) 



Ovate, rufous •; head closely, the thorax very remotely, punctured ; antennae (the two basal joints excepted) 

 black ; elytra black, strongly punctate-striate, the interstices longitudinally costate. 



cJ . The sixth joint of the antennae thickened and elongate. 



Yar. Entirely fulvous ; antennae as in the type. 



Length 2|-3 lines. 



c? . Head closely punctured at the vertex ; the frontal tubercles in the shape of a strongly-raised transverse 

 ridge ; antennae half the length of the body, the two basal joints and the apical one fulvous, the rest black, 

 the third joint elongate, the fourth and fifth joints short, not longer than the second, the sixth much thickened 

 and the longest, the rest short and nearly equal in length ; thorax twice as broad as long, the sides nearly 

 straight, slightly flattened near the lateral margin, the surface without depressions, with a few fine very 

 distantly placed punctures, rufous ; scutellum fulvous or rufous ; elytra much wider at the base than the 

 thorax, with a deep depression placed transversely below the base, black, very strongly punctate-striate, 

 the interstices, especially near the sides, costate ; posterior femora strongly incrassate, extending to the 

 apices of the elytra. 



9 . The fifth and sixth joints of the antennae widened and much longer than the following joints, but much
