Coleopiera from Chontales. 209 



LagocJieirns araneiformis, Lin. Syst. Nat. II. p. 625. — 

 Several examples from Chontales, differing very slightly 

 from the type form from Guiana and the Amazons region. 



Lagocheirus cristulatus, n. sp. — L. aranciformi convexior, 

 paulo minus elongatus postice magis angustatus, elytria 

 basi haud transversim fusco-notatis, antennis griseo-an- 

 nulatis. Pallide fuscus, thorace dorso 5-tuberculato, 2 

 anticis obtusis, 3 postei-ioribus fortiter elevatis, conicis ; 

 elytris apice juxta suturam breviter oblique et obtuse 

 truncatis, medio baseos gibbosis, carina centro-basali 

 an tice dente forti erecto armato, deinde fasciculato-cristato, 

 disco post medium obtuse 5 carinatis, carinis nigro-fasci- 

 culatis, punctatis, macula semicirculari laterali fusca apud 

 medium antice in vittam marginali continuata, fasciaque 

 lata valde flexuosa post medium, ochreo-grisea ; antennis 

 (c?) quam in L. araneiformi multo brevioribus, fuscis, 

 articulis 3-6 griseo-biannulatis ; tarsis omnino nigris. 



Long. 9 lin. $ . 



Quite distinct from all the varieties of L. araneiformis. 

 The lateral brown patch is more rounded, and advances 

 much less towards the disc, than in L. araneiformis. 



This species may, possibly, be the L. ohsoletus, Thorns. 

 Classif. des Cerarab. p. 10 ; but beyond the faintness of 

 the usual markings of this genus implied in his descrip- 

 tion, none of the really distinguishing characters, nor the 

 strongly flexuous pale fasciee are mentioned; so that it 

 must be a distinct allied species found in Mexico. 



Lagocheirus prcecellens, n. sp. — L. araneiformi differt 

 colore purpureo-fusca, elytris minus parallelis, etc. Supra 

 Isete fuscescenti-purpureus ; thorace dorso tuberibus 5 

 vix elevatis, obtusissirais, interstitiis grosse punctatis, 

 maculis fuscis ut in L. araneiformi; elytris apice obtu- 

 sissime suboblique truncatis, medio baseos tuberculo 

 elevate, sed carina centro-basali haud distincta, penicillia 

 nigris parvis lineatim maculatis, et passim fortiter 

 punctatis, punctis postice nigris, pone medium fascia 

 transversali (antice flexuosa et distincta postice fusco- 

 marginata) maculaque apicali ad suturam canis; macula 

 fusca laterali saturate purpurea, antennis fuscis, articulis 

 3-4 griseo bi- 5-10 uni-annulatis ; pectore et abdomine 

 medio griseis, lateribus fulvis ; pedibus griseo et nigro 

 variegatis, tarsis articulis 1-2 griseis, 3-4 nigris.
