— Abdomen transversum, thorace breveus. Oophthora: — 
Abdomen subcylindricum, thorace longeus“. This appears 
undoubtedly rather bold, when considering that Westwood, 
who naturally just as all the older collectors mounted their 
specimens on pins or card, only had dried specimens to 
description from, whilst Aurivillius had fresh, and even living 
specimens in numbers for his examinations. Max Wolff, 
who apparently is not aware of Aurivillius' work at all, 
states at once that the species bred by him is a 7richo- 
gramma, and places it in this genus. In Russia, where 
much work is done in practical Entomology, the genus 
is well known, and the name Trichogramma semblidis 
(not Oopthora semblidis) is used for the species. As far as 
I am able to judge from the literature I have seen, it is 
finally agreed now in 1917 to use the name Trichogramma, 
with Trichogramma evanescens Westwood, as type. 
This genus has of late years won a renown that has 
gone out to all parts of the world, being used in econo- 
mic entomological work in the fight against injurious 
Lepidoptera. This fight was first commenced in North 
America, and as regards the results that have been ob- 
tained I can refer to Howard and Fiske: Bulletin No. 91. 
U. S. Dep. of Agriculture. Washington. 1912. 
In Russia also the genus is beneficially used, the nu- 
merous articles issued by the various entomological sta- 
tions in that great empire bearing witness hereof. The fol- 
lowing are a few examples: Herald of the Sugar Industry, 
Kiew 1913. 11 pp. Reports for 1912 from the Kiew Ento- 
mological station, Kiew 1913. Turkestan Ent. Station, Tash- 
kent 1913. 28 pp. Report of the chief entomologist to the 
Semstvo Simferopol 1913. p.1—23. Memoirs of the Bureau 
of Entomology, St. Petersburg 1913. X. Nr. 4. (An interesting 
article as to how it is possible to breed Oopthora sem- 
blidis in the winter by help of Phalera bucephala L.) —
