THE ENTOMOLOGIST. 



degree of confidence, that he was dealing with that form which 

 was described two years later by Brunner von Wattenwyl under 

 the name of C. pancici. 



A comparison of the five European species gives us a founda- 

 tion for the following synoptical table for their determination : — 



1. (2) 



2. (1) 



3. (6) 



4. (5) 



5. (4) 



6. (3) 



7. (8) 



8. (7), 



Pronotum (male) strongly inflated pos- 

 teriorly. Subgenital lamina (male) very 

 convex, with a broad emargination 



Pronotum not inflated. 



Mesosternal lobes cylindrical. 



Length of mesosternal lobes equal to 

 theirbreadth. Subgenitallamina (male) 

 with slight emargination, but with 

 ridges on the sides ; female rounded 

 posteriorly apically, with a sharp tooth 

 in the inner margin ; pointed apically 

 in female ...... 



Mesosternal lobes longer than broad. 

 Subgenital lamina (male) entire, with 

 lateral ridges ; in the female broad, 

 emarginate posteriorly and laterally, 

 with teeth at the posterior angles and 

 at the base; cerci (male) conical and 

 pointed with a strong tooth ; same in 

 female ...... 



Mesosternal lobes obtusely triangular ; 

 subgenital lamina (male) entire, with 

 lateral ridges, but rounded in the female 

 with an apical emargination, and cerci 

 (male) cylindrical and rounded, but 

 short in female, conical and pointed. 



Mesosternal lobes blunt at the apex. 

 Metasternal lobes blunt, rounded api- 

 cally, slightly longer than broad 

 Mesosternal lobes pointed apically ; 

 metasternal lobes narrow, longer than 

 broad, parallel, pointed at the apex 

 itself ....... 



C. dilatatus, Stal. 



C. o?iiscus, Charp. 



C. longicollis, Schulth. 



C. montandoni, Burr. 



C. braimeri, Shug. 



From this table it is evident that C. brauneri, Shug., stands 

 nearest to C. montandoni, Burr, and it is possible that both 

 species may turn out to be local races of one form ; for the deter- 

 mination of this question, it is necessary to have material from 

 all localities north, north-west, and north-east of the shores of the 

 Black Sea. At the present time, when in the Zoological Museum 

 of the Imperial Academy of Sciences at St. Petersburg there are 

 only sixteen specimens of Callimenus of various species, and in 

 the National History Museum of the Chersonese only two,* and
