The author has examined the genitalia of the males of 39 species, 
with the following results : 1, the numerous forms are divided into two 
groups, primary (probably metamorphosed parts of abdominal segments), 
and accessory (probably cuticular formations) ; 2, the structure is very 
variable, containing many special types, even in genera of small extent ; 
3, the formation follows no family series, but there are 3 separate 
groups, not as yet connected, though in themselves merging by easy 
steps (these groups, according to a diagram, p. 199, being typically 
represented by Xyloterus lineatus, Hylurgus piniperda, and Scolytus 
rugulosus) ; 4, the various differences afford a probability of our under- 
standing the true analogies of the family. The author discusses in detail 
and figures the organs in Scolytus, the Hylesinides, and Tomicides, in a 
manner not easily capable of abstraction, biit worthy of the most atten- 
tive study ; this paper being probably the most philosophical on any ento- 
mological subject published during the year. 
Lindemann also describes three forms of the digestive apparatus in 
the proventriculus of the Scolytidoe, the 1st peculiar to Scolytus, the 
2nd to the Tomicides (?), and the 3rd to the Hylesinides. A specifically 
characteristic appendage at the basal inner angle of the mandible in most 
Scolytidoe, of which an analogue is found is many Curculionidce (espe- 
cially Rhyncolus), is also described. Tageblatt, p. 102, of Entomolo-
