Remarks. C. (s. str.) arida is characterized by the following character states: pronotum entirely black and sparsely punctured at each side; median lobe covered with dense setae on the ventral side at apical one-sixth (Fig. 6 F).

According to Medvedev (1961), the dorsal color patterns of C. (s. str.) arida are variable. Three patterns occur in China. The first pattern has a large humeral spot and a transverse band at apical two-fifths of each elytron (Fig. 13 B); the second pattern has a much smaller humeral spot and a reduced band at apical two-fifths of each elytron (Fig. 13 A); the third pattern has only a humeral spot without transverse band (Fig. 13 C).

Gressitt & Kimoto (1961) and Tan et al. (1980) recorded C. (s. str.) laeviuscula from the north of China. After examination of type material from ZMHB and all specimens in IZ-CAS, we found that specimens identified as C. (s. str.) laeviuscula by the authors above-mentioned to be C. (s. str.) arida based on the median lobe morphology.
