SYNOPTIC TABLE OF CERAMBYCID LARVZ.* 
Head transverse ; longitudinal diameter of occipital opening (foramen cervicale) gen- 
erally shorter than the transverse diameter ; posterior part of head, 7. e. part in- 
vaginated into the prothoracic segment, not divided by a longitudinal wall,

into two halves by a longitudinal wall to which the muscles of the mandibles 
are attached [fiv. 2].

The two sub-families in the above table are those proposed by 
James Thomson in 1864 (S.stema Cerambycidarum), and Ganglbauer 
maintains that this division is justified by the fundamental difference in 
the structure of the larval head (figs. 1 and 2). The second sub-family, 
Lamite (Yhomson’s JZefaulacnemite) corresponds exactly with the 
Lamine of our Classification by Leconte and Horn. His division 
Prionini of the first subfamily, Cerambycite (Thomson’s Analaucnemite), 
corresponds with the sub-family Pr7omimce of Leconte and Horn and his 
two remaining divisions combined correspond with Leconte and Horn’s 
sub-family Cer ambycine. From his synoptic table of the imagos (I. ¢., 
p. 684) it is evident that Ganglbauer has great difficulty in separating his 
Lepturini as equivalent to the Prionini and Cerambycint and Leconte and 
Horn include them as a ‘‘series,” Zep/uroides, in the sub-family Ceram- 
bycint : but from the larval characters it would appear that the Lep/urint 
are not only most readily separated from but also equivalent to the Prz- 
onine and Cerambycine. 
The importance of the above table for the determination of Ceram- 
bycid larvze is evident ; all that is necessary to do is to detach the head 
of the larva, and a glance at the occipital opening and the pleurze of the 
head will be sufficient to refer the larva—even without the aid of a lens— 
to one of the great divisions of the family. i. Boas 
* The above table expressed in the original language used by Schicedte and com- 
piled from the Conspectus morphologicus and Conspectus systematicus, reads as 
follows :
