BUPRESTIS STRIGOSA Gebler 



Buprestis strigosa Gebler, Ledebours Reise, vol. 2, pt. 2, 1S30, pp. 78-79. 



This species was described by Gebler from Siberia, and was reported 

 by him as having been collected frequently in the Alta Mountains 

 and Davuria, and rarely at Barnaul. Motschulsky^ reports it as 

 common with Buprestis haemorrhoidalis Herbst {B. punctata Fabricius) 

 in the forests of fir near the northern part of the Amur River, and 

 gives it the varietal nsLiae Jiavosparsa without giving a description of 

 it. It seems to be a common species and widely distributed through- 

 out Siberia and Mongolia. 



Nine specimens, five males and four females, were examined, of 

 which seven were collected by A. I. Lavrushin along the Amagu 

 River during July, 1923, and the other two by T. D. A. Cockerell 

 Along the Kudia River, in the Province of Amagu, during July, 1923. 



The color markings are quite variable in this species; some have 

 the elytra immaculate, while in others the yellow markings are quite 

 distinct. The yellow spot at apical angle of pronotum is also variable 

 in size, and is entirely absent in one specimen. 



The males have a large broad hook at the tip of the anterior tibiae, 

 and the last abdominal segment is feebly arcuately emarginate at 

 the apex, and usually only the last segment ornated with yellow 

 spots at the sides, but in one specimen these spots are entirely absent. 



In the females the anterior tibiae are not armed with a hook, and 

 usually all of the abdominal segments are marked with yellow spots 

 at the sides, and the last segment is broadly truncate at apex. 



BUPRESTIS HAEMORRHOIDALIS Herbst 



Buprestis haemorrhoidalis Herbst, Schriften Berl. Gesellsch. Nat. Freunde, vol. 



1, 1779, p. 97. 



Herbst described this species under the above name from Europe, 

 and later it was described by a number of other writers under 

 various names, all of which have been placed as synonyms of 

 haemorrJioidalis by Kerremans.^ Motschulsky,* under the name of 

 Buprestis punctata Fabricius (placed as a synonym of haemorrlwidalis 

 by Kerremans) , records it as being very common in the forests of 

 fir near the northern part of the Amur River in eastern Siberia. 

 The color markings on this species are also variable, and if the 

 synonym given by Kerremans is correct, the species has a wide 

 distribution, living in the conifers throughout Europe and Siberia.
