elytra more coarsely, punctate, llie latter with finer punctures intermixed. 

 Head rather small, foveate on each side near the eyes, the latter large ; 

 antennae moderately lono', joints 2 and 3 short, equal, the others elongate, not 

 very slender. Prothorax rapidly narrowed from the base, deeply hollowed in 

 frout opposite the eyes, the anterior angles prominent. Elytra rather convex, 

 flattened on the disc, strongly rounded and sharply margined laterally, without 

 raised lines or grooves. Posterior coxae without plate. Posterior tibiae rather 

 broad, cariuate. 



Length 3^, breadth 2^ mm. 

 Hah. Assam, Patkai Mts. {Doherty, ex coll. Fri/). 



Two specimens, sex not ascertained. Smaller than the Indian 

 O. {Galleruca) i^icta F., the elytra more rounded at the sides, the 

 sharply- defined irregular markings mainly restricted to the apical half, 

 and pai*tly condensed into two, common, angulate fasciae. The punc- 

 tm'es on the el^^tra are unequal in size, and here and there transversely 

 confluent, in both species. Scirtes nigronotcdiis Pic (1913), from 

 Sumbawa (compared by him with ;S^. difficilis Waterh.), may be an 

 allied form ?

Motschulsky's length}' diagnosis applies well to the insect subse- 

 quently described by Waterhouse. There are seven specimens of this 

 species in the Museum, including the type of S. irregidtiris, which is 

 a $ , the males having the elytra less dilated at the middle. The two 

 examples from Kina Balu have the markings (five rows of scattered 

 minute dots in the typical form) more extended on the disc of the elytra 

 and partly confluent. The elytral surface is feebly tricostate and here and 

 there raised or swollen, thus appearing very uneven. The jDOsterior coxae 

 are without angular plate. The two dark spots on the head, mentioned 

 by both authors, each arise from a deep fovea. 0. nigropunctata is 

 evidently a widely-distributed form in the Malayan region. 



19. — Ora rugosissima, n. sp. 



$ . Hemispherical, convex, moderately shining, thickly cinereo-pubescent ; 

 the antennae (joints 1 and 2 excepted), upper surface, and the legs in part, 

 piceous, the under surface (the elytral epipleura excepted), two short, oblique, 

 coaiescent streaks at the base of each elytron, and the posterior tibiae and tarsi.
