with the genus of that name as restricted by EichhofF and with Bostrychus 
(Zimm.). The known species referred to it by Leconte are T. calligraphus 
(Germ.) = ? exesm prcemoi'sus (Eichh.), Bodr.pini rictus 
(Eichh.), Bostr. interruptus, tridens, and coneinnus (Mann.), and T. avulsus 
(Eichh.). The Scolytini, as already stated, are represented only by the genus 
Scolytus, to which Leconte refers seven species, three of them described as 
new; the others are S. quadrispinosus (Say), (Walsh, Pract. Entom. hi 
p. 68), carytx (Riley, Prairie Farmer, 1867 ; Walsh, Pract. Entom. ii. p. 68), 
and S, muticus (Say). 
Of the Jlylurgini Leconte tabulates the genera as follows (7 c. p. 168) ; — 
I. Club of antennm large, much compressed, uniformly pubescent; joints 
of tarsi not dilated, scarcely emarginate. 
A. Funiculus very short, 1-jointed .... 1. Chramesus, g. n. 
B. Funiculus longer, 6-jointed 2. Polygraphus (Erichs.). 
II. Club of antennm lamellate 3. Phlceotribus (Lat.). 
III. Club of antennse annulated. 
A. Ventral segments subequal. 
а. Club oval, elongate, or fusiform. 
1. Front ti biro serrate 4. IIylesinus (Fab.). 
2. Front tibioo coarsely toothed . ... 6. Cnesinus, g. n. 
б. Club oval, smaller, subacute. 
1. Tarsi with joints 1-3 equal .... 6. Hylijrgus (Lat.). 
2. Tarsi with joint 1 shorter 7. Carphoborus (Eichh.). 
c. Club short, broad, compressed, and concave. 
8. Bendroctonus (Erichs.). 
B. Ventral segments 1 and 6 elongate, sutures very deeply impressed ; 
club small, oval, basal half glabrous 9. IIylastes (Erichs.). 
To Polygraphus Ijeconte refers only Apate rufipennis (l^ixhy) -\-nigriceps 
(Kirby) =P. saginatus (Mann.). IIylesinus includes ten species, two described 
as new. The known species are II. imperialis (Eichh.), sericeus (Mann.), 
dentatus (Say), and nehulosus, serratus, cristatus, and hystrix (Lee.). Hylur- 
gus includes only one new species, the species described under this genus 
by Zimmermann {vide infrd) belonging to IIylastes. Carphoborus includes 
only C. hifurcus (Eichh.). To Dcndroctonus six species are referred, namely 
I), terebrans (Lac.)=p«/c;?5 (Lee.), Ilylurgus obesus (Mann.) = 2). shnilis 
(Lee.), Hyl. rujipennis (Kirby) and three new species described by Leconte 
and Zimmermann. Under Hylastcs, which he regards as approaching most 
closely to the Cossonide Curculionida3, Leconte cites eleven North- American 
species, six described as new by himself and Zimmermann (vide infra) and 
the following known species: — H. porculus — scabripe^inis (Zimm,), 
nigrinus (Mann.), pinifex (Fitch), rugipennis (Mann.), and subcostidatus 
(Mann.). Leconte gives a list of fourteen described North-American species 
with which he is imacquainted. 
Monarthrum. Kirsch (Berl. ent. Zeitschr. 1868, p. 214) discusses the affi- 
nities of this genus, which he says must either be placed with Microcorthylus 
as a subgenus of Corthylus, or, if Ferrari’s subgenera Pseudocorthylus and 
Microcorthylus be raised to generic rank, be also maintained as a distinct 
genus. 
Ferrari publishes (Berl. ent. Zeitschr. 1868, pp. 251-256) notes on the fol- 
lowing described species of this family which were unknown to him in nature
