3. NIOROMACITATUS, H.-S. 



Stenobot/irus into four subgenera, which are here treated as distinct 

 genera, for better convenience in dealing with the numerous species. 

 StfnobothrKs in the strict sense is characterised by the long, narrow 

 mediastinal area and by the strong tooth on the valves of the ovipositor, 



Taiu.k of Speciks. 

 1.1. Elytra strongly abbreviated (size small, ulnar vein 



undivided ; Austrian species) . . . . . . 1. crabsipks, Ocsk. 



1.1. Elytra generally developed. (Larger insects.) 



2. CariniB of pronotum slightly diverging anteriorly 

 and posteriorly, slightly bent in in front of 

 the typical sulcus ; ulnar area absent, owing 

 to fusion of the two ulnar veins, or extremely 

 narrow ; very rarely it is distinctly developed, 

 but, in this case, the discoidal area is very much 

 broader, with regular parallel fenestrations 

 3. Ulnar veins fused or united near the base, 

 so that ulnar area is absent. 

 4. Elytra and wings longer than abdomen ; 

 elytra with a white band a little 

 beyond the middle; second radial vein 

 sinuous, and the ulnar veins fused 

 from the base . . 

 4.4. Elytra and wings shorter than abdo- 

 men ; elytra with greyish spots 

 along discoidal area, and a white 

 spot near apex, but no white stripe ; 

 second radial vein straight, and 

 ulnar veins visible separately as far 

 as middle of elytra, where they are 

 fused, but they are contiguous 

 always 

 8.3. Ulnar veins separate throughout their 

 length, though sometimes almost contig- 

 uous, and even fused in a few isolated 

 spots. 

 4. Ulnar area straight, the two veins almost 

 contiguous ; elytra as long as abdomen 

 in ? , and slightly longer in <? , with 

 second radial vein sinuous, the dis- 

 coidal area more or less dark with a 

 large white spot in the middle ot a 

 grey space situated at one third the 

 length of elytra 



4.4. Ulnar area slighty broadened towards 

 apex, the ulnar veins diverging 

 from the base ; elytra generally 

 shorter than abdomen in ? , and 

 slightly longer than cf ; second 

 radial vein straight, the discoidal 

 area crossed by a black band 

 interrupted by white spots, with a 

 small white spot near the apex of 

 elytra . . 

 2.2. Carinse of pronotum distinctly bent in and even 

 almost angled in the prozona, much more 

 strongly diverging behind than anteriorly. 

 Ulnar area gradually broadened from base. 

 3. Smaller ; last segment of palpi of uniform 

 colour; antennic short; carinjf of 

 pronotum angled ; elytra with radial area 

 parallel, or only slightly broadened to- 

 wards apex .. .. .. .. ..6. PESTIVC8, Bol. 



3.3. Larger. Last segment of palpi of different
