Mr. Westwood's Characters of Amydetes. 63 



Kirby, &c. the antennae of which are biflabellate, the flabella on each side 

 arise Irom the same part of the joint, and not (as in the dipterous genus 

 CtenophoraJ from various distances from the base of various jomts. In 

 the two species of my new genus, however, the antennee have upwards of 

 ihirty-five joints, the first and second alone being without pectinations, 

 thus pointing the way to the genus Rhipicera, one species of which, from 

 New Holland, Mr. Kirby describes as having upwards of thirty pectina- 

 tions in the antennse. The genus has doubtless a near affinity with 

 Phengodes, and was separated by Hoffmansegg from the Lampyrides in 

 the same paper in which he established that group. The generic cha- 

 racters given by him were by no means sufficiently detailed, and I have 

 therefore attempted to supply the deficiency. And indeed in regarding 

 the following insects as belonging to this genus, it is proper to state, that 

 lUiger describes the antennse as having " mehr als vierzig Gliedern." 



We may presume that the female when discovered will be found to 

 possess simple antennae. 



The student will find some interesting observations upon the singular 



anomaly of certain insects possessing more or less than the usual number 



of joints in the antennse, in Dalman's Analecta Entomologica, under the 



genus Pobjtomus, and also in Kirby and Spence, Vol. III. 321 and 519.

 The only two specimens which I have yet seen of this insect are males, 

 one is in Mr. Haworth's cabinet, and the other in my own. I had 

 originally named the insect in my MSS. after that gentleman as a slight 

 return for the many entomological favours which I have received from 

 him, and through whose kindness my own collection has been enriched
