The abdominal defensive glands ofC. maxillosus secrete a mixture (70μg/beetle) of isoamyl alcohol (I), isoamyl acetate (II), iridodial (III), actinidine (IV), dihydronepetalactone (VE), and (E)-8-oxocitronellyl acetate (X). When disturbed, the beetle everts the glands and revolves the abdomen so as to wipe the glands against the offending agent. Fecal fluid is commonly emitted at the same time and may become added to the glandular material. Ants (Formica exsectoides) are effectively fended off by the beetle and were shown in bioassays (Monomorium destructor) to be repelled by the four major components of the secretion (II, III, X, VE); the principal component (VE) was the most active. Some anatomical features of the glands are described.
巨胸犀金龟的腹部防御腺分泌一种混合物（每头甲虫 70μg），包含异戊醇（I）、异戊酸乙酯（II）、艾里莫烷（III）、actinidine（IV）、二氢去甲槟榔次酮（VE）和（E）-8-氧代香茅基乙酸酯（X）。当受到干扰时，甲虫会外翻腺体并转动腹部，使腺体摩擦到刺激物。同时通常会排出粪便液，可能会与腺体物质混合。蚂蚁（Formica exsectoides）会被甲虫有效地击退，生物测定（Monomorium destructor）显示，分泌物的四个主要成分（II、III、X、VE）会使蚂蚁感到排斥；主要成分（VE）最为活跃。本文还描述了一些腺体的解剖特征。
