Head strongly convex, nearly covered b} T prothorax and not visible 

 from above, front not produced into a lobe on each side of clypeus, 

 transversely depressed behind clypeus; clypeus strongly transverse, 

 broadly, arcuately emarginate in front, at sides shorter than labrum; 

 labrum broadly rounded and ciliate in front ; mentum strongly trans- 

 verse, truncate in front; maxillary palpi longer than labial palpi, 

 apical segments long, cultiform; labial palpi with apical segments 

 elongate, acute at apices; mandibles robust, with a triangular tooth 

 on inner margin near middle; eyes strongly projecting, transverse, 

 oblong, abruptly defiexed posteriorly. Antenna 10- or 11- segmented ; 

 first and second segments robust, second shorter than first; third to 

 seventh or eighth narrower, more or less transverse, subequal in 

 length ; last three segments forming a large loose club, first two seg- 

 ments of club triangular, apical segment oblong, and broadly rounded 

 at apex. Pronotum subglobose. subequal in length and width, broadly 

 rounded in front, rugose and tuberculate in front, granulose or punc- 

 tate on basal half; sides rounded, distinctly margined posteriorly. 

 Scutellum small, transverse, rectangular. Elytra strongly convex, 

 regularly declivous posteriorly, irregularly punctate. Legs short, 

 subequal in length; tibia slightly expanded toward apices, dentate 

 on exterior margin, anterior pair with an arcuate spine at apices; 

 posterior tarsi shorter than tibiae, last segment of each as long as the 

 preceding four segments united. Anterior and middle coxae con- 

 tiguous. Body moderately elongate, cylindrical. 



Genotype. — Of Dinoderus, Dinoderus oceUaris Stephens. Of 

 Patea, Dinoderus brevis Horn. (Monobasic.) 



This genus is of Oriental origin, but many of the species have been 

 distributed to all parts of the world in commerce. 



Stephens (1830) erected Dinoderus for Apate substriatus Paykull 

 (identification queried) and Dinoderus oceUaris, new species. His 

 identification of substriatus is not the species described by Paykull 

 under that name, and according to Article 30, section B, of the Inter- 

 national Code, "Species which were species inquirendae from the 

 standpoint of the author of the generic name at the time of its pub- 

 lication" are excluded from consideration in determining the types 

 of genera. This leaves only Dinoderus oceUaris Stephens available 

 as the genotype of Dinoderus.
