TL;DR: The attempted synthesis of 4-hydroxy-3-vinyl-2-quinolones, intended precursors for dictamnine and its derivatives, resulted in a cycloaddition reaction leading to a dihydropyrano[3,2-c]quinoline system as mentioned in this paper.

TL;DR: The subrectal glands associated with the female reproductive system is a characteristic feature of Harpactorinae and these glands produce spumaline for gluing eggs to the substratum in a mass.
Abstract: In Reduviidae, the glandular outgrowths from the bursa either as paired or as a single median gland distinctly different from the paired subrectal glands are described as the bursal glands. The occurrence of such female accessory glands has been investigated in 22 species of Reduviidae. Based on their development, the glands are classified into 3 types. The histomorphology of the gland in various species is given.

TL;DR: Inter and intramorph breeding experiments in the laboratory establish the existence of polymorphism in R. marginatus, a reduviid existing in three different morphs, which appears to be a non-mutational, non-adaptive trend in evolution an equivalent of antogenetic evolution.
Abstract: Rhinocoris marginatus Fabricius is a reduviid existing in three different morphs viz., (A) niger (B) sanguineous and (C) nigrosanguineous. Inter and intramorph breeding experiments in the laboratory establish the existence of polymorphism in this species. The sanguineous morph appears to be the most biologically successfull morph and the nigrosanguineous morph appears to be the least successful one. The existence of polymorphism in R. marginatus appears to be a non-mutational, non-adaptive trend in evolution an equivalent of antogenetic evolution.
