tliorace supra et in elytrorum maculis nonnullis nigra, in pro- 

 thoracis maculis nonnullis et in elytrorum partibus discoidalibus 

 (maculis nigris exceptis) fulva ; protliorace (spinis lateralibus 

 exclusis) quam latiori paullo longiori, antice quam postice baud 

 angustiori, supra sat convexo, utrinque spina magna robusta 

 conica instructo, rugulose crassissime punctulato, lateribus minus 

 fortiter arcuatis ; scutello parvo elongato-triangulari ; elytris pro- 

 thorace (spinis lateralibus inclusis) vix latioribus, supra sat leviter 

 (latera versus grosse) sparsim punctulatis, carinis 2 simplicibus 

 instructis (exteriori antice obsoleta, altera antice spinam robustam 

 obtusam suberectam formanti), apice minute divaricatis ; corpora 

 toto, antennis, pedibusque, setis plus minus squamiformibus (alteris 

 albidis alteris nigris) vestitis. [Long. 7|^, lat. 2^ lines. 



The antennae (by measurement) are slightly more than | the 

 length of the whole insect. The spots of fulvous pubescence on 

 the prothorax are not very conspicuous, — one occupies the centre 

 of the disc, another (smaller) is on either side a little in front of 

 the middle. TJie black spots on the elytra are extremely conspi- 

 cuous and are arranged as follows ; — about 9 small spots down 

 each side of the suture (the last 3 or 4 more or less confluent on 

 each row), — the basal tubercle and about 4 spots (the 2nd and 3rd 

 largest) on the discoidal carina, — a very large spot of irregular 

 form extending from near the lateral margin to near the discoidal 

 carina and longitudinally from the apex of the basal I of the 

 elytron to the middle, — two or three spots on the defined part of 

 the external carina ; all the punctures on the elytra also more or 

 less black. 



Near M. Arachne, Pasc, and sticticus, Pasc. From the former 

 it differs inter alia in colour (e g. head pale grey instead of dark 

 brown), also in having the external elytral carina scarcely traceable 

 except in its hinder half instead of " entire and well marked ;" from 

 the latter in having the pubescence of the black spots (apart from 

 colour) quite similar to that of the rest of the surface instead of 

 " composed of stiff erect hairs * * * raised above the sur- 

 rounding pubescence." The discoidal carina is bent round towards
