LACHNO STERNA. 197 



Three examples, besides one in my own collection received from Paris under the 

 name L. rorida, Burm., from which it is evidently distinct, and which is, moreover, 

 a South-Brazilian insect. I have seen only one male (from Teapa) ; it differs slightly 

 from the three females, and is much smaller (20 millim., the females being 25 millim.), 

 and seems intermediate between this species and L. rondenta, but the punctures have 

 each a small grey seta. 



26. Lachnosterna cinnamomea. (Tab. XL fig. 8.) 



Ancylonycha cinnamomea, Blanch. Cat. Coll. Ent. i. p. 134 . 

 Hob. Mexico 1 , Cordova {Salle). 



Extremely near L.parvisetis, but glabrous, without pruinose bloom, and the punctures 

 naked. Colour castaneous, shining. In the male the pygidium is polished and flattened 

 towards the apex ; the lower hind spur is rather longer than in L. rondenta, but soldered 

 to the tibia ; the ventral segments are sculptured precisely as in that species. In the 

 female the pygidium differs in the apical area being more depressed and margined 

 laterally by much higher ridges. 



2. Lower spur of the hind tibice freely articulated. 



27. Lachnosterna sturmi. (Tab. XI. fig. 9, $ .) 



Phytalo pruinoso similis. Anguste oblonga, suboylindrica, fuligineo-nigra, elytris plerumque rufescentibus, 

 supra toto pruinosa ; pedibus castaneis. politis ; clypeo antice medio profunde subacute sinuato, capite toto 

 dense punctato ; tborace elytrisque disperse umbilicato-punctulatis, punctis (prope elytrorum apicem 

 breviter setosis exceptis) nudis ; pectore minus dense incumbenti-fulvo-piloso ; antennis castaneis, clava 

 fulvescente. 

 cJ . Pygidium mediocriter convexum, apice renexum, disperse umbilicato-punctatum, nudum. Venter medio 

 canaliculars, sublawis, segmento 5° apice medio depresso ibique aspere punctato, polito, 6° transversim 

 subdepresso rugoso. Calcaria postica libera, ensiformes, inferiore multo breviore. Ungues dente inferiore 

 valido baud breviore, submediano ; basi parum dilatati. Antennarum clava paullo elongata, articulis 

 2°-7 m aequalis. 



2 . Pygidium subtriangulare, convexum, lateraliter subcompressum, apice renexum. Venter medio sparse 

 lateribus densius punctulato-pi]osus, segmento 6° convexo, postice grossius punctato. Ungues sicut in <j . 



Long. 18-22 millim. 



Hob. Mexico, Cordova, Orizaba, Tuxtla, Playa Vicente (Salle). 



Closely resembling in form and sculpture Phytalus pruinosus, but widely differing in 

 the spurs of the hind tibige of the male, the form of the tarsal claws, and other important 

 points of structure. It appears to have been hitherto confounded with P. pruinosus 

 (Burm.) ; it being so named in the Salle collection (by Sturm) and in my own from 

 specimens received years ago from Paris. I have examined nine examples. 



The clypeus is a little more deeply notched in the middle of the front margin than 

 in P. /pruinosus, and the sides are less convergent. 



Our figure is taken from a female specimen from Tuxtla.
