108 GRAMMAR OF ENTOMOLOGY. 



of the joints takes place without any marked 

 indentation or protuberance. 



365. Filiform antennae (antennae filiformes) 

 are usually stouter and shorter, and preserve 

 throughout a uniform substance. 



366. Incrassated antennae (antennae accres- 

 centes) resemble the last, excepting that they 

 gradually increase in substance towards the apex. 



367. Fusiform antennae (antennae fusiformes) 

 are stoutest at the middle, and taper very gradu- 

 ally to each end. 



368. Moniliform antennas (antennae monili- 

 formes) differ from the filiform in one character 

 only : each separate joint is oval or globose, and 

 the portion connecting it with the next is very 

 slender ; the joints thus resembling beads on a 

 string. 



369. Serrated antennae (antennae serratae) have 

 each joint produced on one side at the apex, so 

 that together they resemble the teeth of a saw. 



370. Pectinate antennae (antennae pectini- 

 formes) are those in which the joints are still 

 more produced, or rather, are furnished on one 

 side with slender processes, resembling, in some 

 degree, the teeth of a comb. 



371. Flabellate antennae (antennae flabelli- 

 formes) have the processes of the joints still 

 longer, very thin, and, when at rest, lying flat on 

 each other, like the folds of a fan : the antennae
