316 BEV. H. S. GOBHAM ON THE [Apr. 19, 



This is a small parallel species of Calopteron belonging to 

 Section A. iii. in ' Biologia C.-Am.,' with four raised Hnes on each 

 elytron, and the thorax with a simple carina. The antennae are 

 nearly simple in both sexes. The bases of the femora and the 

 coxaeare often a little yellow, but only so at the joint. 



The colouring of this insect is almost exactly that of Emplectus 

 Icetiis Er., and is also very like that of Oalocladon ephippium Gorh. 

 It would also at first sight be apt to be confounded with the 

 species which follows (C delicatum Kirsch), but in addition to the 

 form of the central black patch, there are minute differences in 

 the sculpture. The costse and cells are more distinctly raised in 

 this insect ; it is also wider behind, and hence less parallel. 

 The females are, as usual, larger and wider than the males. 



About twenty examples.

Some examples of this little insect are very like C. smithi ; the 

 central black fascia, however, always reaches the margin ; and the 

 suture from the base to the fascia is black. The apical fifth is 

 black ; it is more parallel ; the second and fourth costae are dis- 

 tinct, but the first and third are very indistinct. The examples, 

 nine in number, from Balthazar, all agree very closely, and are 

 7 to 10 millimetres long. One from Mount Maitland has the 

 central patch detached from the base, and so far resembles 

 C. smithi, but in other points agrees with C. delicatum, and, being 

 from the same side of the Island of Grenada, I have no doubt 

 pertains to this species.

Hab. Grenada : Grand Etang, 1900 feet, St. Vincent, Kings- 

 town, and windward side to 1500 feet (E. H. Smith). 



This little species is of the size and form of C. delicatum, but it 

 wants the central black fascia, and the thorax is entirely yellow. 

 The pattern is one common to many Lycidae. One-third of the 

 apex of the elytra is black, and there is a more or less ex- 

 tended black smear down the suture, sometimes but rarely joined 

 to the apical black. The scutellum is yellow, or at least with 

 yellow scales. The antennae are about as long as in C. delicatum, 

 i. e. about as long as the elytra. The two raised costae are very 

 strongly elevated, while the intermediate ones and the areolets 

 are very indistinct.
