the individuals of the respective species, wherever an opportunity 

 has occurred to inspect a series of examples. The elytra are 

 separately rounded at apex and mutually overlap for a consider- 

 able distance, the fine raised line indicating the limit of overlap 

 diverging on each from the inner edge posteriorly. The hind 

 wings are fringed with stiff erect hairs. There is a terminal 

 dorsal pygidium which is entirely concealed by the elytra. The 

 integuments are always rather plentifully clothed with hair, which 

 is simple in structure on the elytra, but intermingled with shorter 

 and stiffer spicules on the anterior parts ; it is directed backward 

 on the head and densely clothes the basal parts ; there is also a 

 short erect and oblique fringe at each side of the occiput. 



The sexual characters are very feeble as a rule, but in the very 

 minute biceps, and, to a less degree, in caviceps, become extremely 

 pronounced, the head in the male being modified to as great a 

 degree as in Batrisus. In frontale and its immediate allies there 

 is a small pubescent area between the antennal prominences which 

 is wanting in the female, but beside these cases I have noticed no 

 sexual modification in any part of the body, except occasionally 

 a very slight one in general form. The terminal spur of the hind 

 tibiae in the males of a large section of the genus, is a character 

 altogether peculiar to Connophron. The form of the oedeagus is 

 noticed under the descriptions of those species in which it hap- 

 pened to be visible in the particular representative studied, but 

 the organ is seldom protruded in mounted specimens. 



The species are exceedingly numerous and those which I have 

 before me seem to be conveniently classified as follows : — 



Basal joint of the hind tarsi not, or scarcely, longer than the second, the first 

 four joints subequal among themselves; hind coxse moderately separated, 

 the abdominal process obtuse; posterior margin of the first segment simple; 

 hind tibiae of the male never calcarate at apex, except in certain small 



species with simple clypeal margin 2 



Basal joint of the hind tarsi elongate, always distinctly longer than the second, 

 the joints one to four decreasing rapidly in length, the tarsi frequently 

 very slender and filiform; hind coxse more approximate, the abdominal 

 process angulate; posterior margin of the first segment arcuate and gener- 

 ally fringed with membranous hairs or a coriaceous border ; hind tibiae of 



the male with a slender terminal process 33 



2 — Antennal club 4-jointed, frequently gradual in formation 3 



Antennal club 3-jointed, always abruptly formed 32 



3 — Clypens toothed at the middle of the apical margin, the tooth sometimes 

 minute 4
