14. OrtJioperiis minutissimus, Matthews (?). 

 (PI. V. fig. 41.) 



Orthoperus mmutissimus, Matthews, Mon. Corylophidfe, 1899, p. 196. 



A single (^, in bad pi'eservation. Pitchy fuscous, leg< 

 and antennai lighter, shining and quite glabrous above. 

 Tiiovax not (or scarcely) punctured. Elytra finely and sub- 

 obsoletely punctured, the punctures more than their own 

 diameter a|)arfc. Ventrally tlie metasternum is impuncfcate 

 in tiie middle, bat its sides and the first abilominal segment 

 have very fine punctures several times their own diameter 

 apart. Wings not examined. 



So far as can be seen in its bad icondition, the specimen 

 agrees in size, colour, and punctuation with an example in 

 Matthews's Collfction from Grenada, West Indies, placed as 

 O. minutlssiinus'^. The two agree particularly' in the form 

 o£ the front tibiee, which are sharply incurved at tlie apex, 

 the inner apical angle forming a sharp heel. Fig. 44 shows 

 the right-hand front tibia in the West-Indian specimen. 



Log. Seychelles : Silhouette, from Mare aux Oochons, 

 1000 feet or more, ix. 1908. 0. minufissimufi, Matth., is 

 recorded from South America and West Indies. 



15. Orthoperus sp. 



Among the material from Rangoon is a single specimen, 

 peihiips not full)- mature, of a very minute species, quite 

 distinct from 0. munice by the absence of the basal thoracic 

 series of punctures. In size and punctuation of the u|)per 

 surface it is not unlike tlie example from Silhouette described 

 above- and reCerred to 0. minutis shims. It is just possible 

 that it is a ? of that species, since it probably belongs to the 

 $ sex, the front tibisenot being incurved and having no sharp 

 heel. The metasternum appears quite impunctate, even at 

 the sides ; diverging striai perfectly distinct but not punc- 

 tured. Determination or further description of this form is 

 impossible in the absence of more uiaterial. Wings not 

 examined. 



• The name and description of O. mimitissiinus Rxe^whYvfihe^ in square 

 brackets in Matthews's Monograph, from his own ]MS. notes, by P. 13. 

 Mason, editor of the Mouog-raph. Mason gives reasons for thinking that 

 Mattliews probably intended to sink tliis name as a synonym of O. pev- 

 pusillns, Matth. 1 have, however, provisionally retained the name 

 minutissiniKS, since time has not admitted of an examination of Matthews's 

 material sufficiently close to decide whether minutissimus and perpusillus 

 are identical or not.
