 SVNOPTIC TABLE OF CERAMBYCID LARV^^ 



Head transverse ; lonyittidinal diameter of occipital opening (foramen cervicale) 'gen- 

 erally shorter than the transverse diameter ; posterior part of head, /. c. part m- 

 vaginated into the prothoracic segment, not divided by a longitudinal waM. . . . 



[fig. I] CERAMBYCITiE 



Pleurce of head dorsally entirely separated, diverging posteriorly 



[fig. 3] Lepturini 

 Pleurti; of head dorsally anteriorly connate, posteriorly separated and diverging 



[fig. 4] Prionini 



Pleurae of head connate tliroiighoat, posteriorly separately rounded 



[fig. i] Cerambycini 



Head oblong, much longer than wide ; longitudinal diameter of occipital opening 



much longer than the transverse diameter ; invaginated portion of head divided 



into two halves by a longitudinal wall to which the muscles of the mandibles 



are attachctl [fi,'. 2]. 



Pleura; ot head doi ;,ally connate throughout, posterioily conjointly rounded 



[fig. 5] LAMIITiE 



Tne two sub-(amilits in the above table are thohC proposed by 

 James ThoMis Ml ni 186-1. (S sterna Cerambycidarum), and Ganglbauer 

 maintains ttiai tliis division is justified by the fundamental difference in 

 the structure of the larval head (figs, i and 2). The second sub-family, 

 LamiiicB (Thomson's Aletaidacneinitce) corresponds exactly with the 

 Lamiin.e of our Classification by Leconte and Horn. His division 

 Prionini o{ \\iQ first subfamily, Cerambycitce (Thomson's AnalauctiemiLe), 

 corresponds with the sub-family Prioninie of Leconte and Horn and his 

 two remaining divisions comliined correspond with Leconte and Horn's 

 sub-family Cernmbyci^ice. From his synoptic table of the imagos (1. c. , 

 p. 684) it is evident that Ganglbauer has great difficulty in separating his 

 Lepiurifti ?iS equivalent to the Prionini ^nd Cera??ibvcini ■A.nd Leconte and 

 Horn include them as a "series," Lepturoides, in the sub-family Ceram- 

 bycini: but from the larval characters it would appear that the Lepturini 

 are not only most readily separated from but also equivalent to the Pri- 

 onince and Cerambycince. 



The importance of the above table for the determination of Ceram- 

 bycid larvae 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 pleurae 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. J. B. S. 



* The above table expressed in the original language used by Schicedte and com- 

 piled from the Conspectus morphologicus and Conspectus systematicus, reads as 

 follows : 

 Foramen cervicare transverse rotundatum. 



Pleura; capitis pone epistoma spatio longiole concretfe, post dehiscentes, angulatre. . 



Prionini 



Pleurre capitis pone epistoma ad apicem ferme concretce, post singulatim rotiuulatre. . 



Cerambycini 



Pleura; capitis pone epistoma dehiscentes, angulata; Lepturini 



Foramen cervicale oblonge ovatum, septo divisum ante decrescente, cui musculi ad- 



ductores mandibularum affiguntur. 



Pleurae capitis pone epistoma per totam longitudinem concrete, post conjunctim 



rotundatre Lamiini
