188 LAMELLICORNIA. 



Hah. British Honduras, R. Sarstoon (Blancaneaux) ; Guatemala, Cerro Zunil 

 (Champion). 



Two examples, both females. Closely allied to L. piceola, but differing too much in 

 the outline of the clypeus and in the punctuation of the thorax to admit of the suppo- 

 sition that it is the female of that species. The Guatemalan example is figured. 



6. Lachnosterna leonina. (Tab. X. fig. 22, e .) 



L. cribricolli et L. rugicolU proxime affinis ; differt corpore toto fusco-nigro, antennis pedibusque rufioribus, 

 utroque sexu thorace elytrorumque basi et prope suturam pilis valde elongatis erectis obsitis elytrisque 

 lateribus quoque breviter griseo-pilosis ; clypeo parvo, extus sat late rotundato ( J ), antice medio late 

 sinuato ; tborace medio valde dilatato, antice leviter sinuatim angustato, angulis anticis acutis, grossissime 

 et dense sed parum conflnenter punctato ; elytris pauilo grossius quam in L. cribricolli, multo grossius 

 quam in L. rugicolU, punctatis, costis sat perspicuis ; pectore pallide fulvo-villoso abdomineque lateribus 

 incumbente sat dense pubescentibus. Antennae 10-articulatas. 



3 . Pygidium mediocriter convexum, nitidum, vage parum profunde punctatum, longe erecte hirsutum, apice 

 glabrum. Venter medio convexus, politus, interdum subtiliter canaliculatus, segmento 5° apice arcuatim 

 emarginato, medio apice dense punctulato, segmento 6° magno, medio area depressa setifero-punctulata. 

 Calcaria postica libera, superiore acuto inferiore subspathulato. Ungues basi quadrato-dilatati, dente 

 mediano cum dente superiore fere paralleli sed illo paullo latiore et breviore, dentibus tribus basi approxi- 

 matis. Antennarum clava sat brevi. 



2 ? Pygidium planum, vage rugoso-punctatum, setiferum. Venter medio convexus, lasvis, segmento 6° simplici, 

 punctis nonnullis grossis. Clypeus lateribus baud late rotundatis, arcuatus, medio antice sat acute inciso- 

 sinuatus. 



Long. 13-16 millim. 



Bab. Mexico, Toluca, Peras (Salle). 



Two males from Toluca ; two females from Peras : the difference in the outline of 

 the clypeus may, therefore, indicate a local variety. In all other points the specimens 

 agree perfectly. They are named L. foveicollis, Sturm, in the Salle collection, but are 

 certainly a different species from the one described under that name by Sturm. 



A male specimen from Toluca is figured. 



7. Lachnosterna pubicauda. 



L. leonince affinis ; differt colore toto rufo-testaceo pygidioque crebre punctulato, et longe pubescente. Tborax 

 antice tenuiter marginatus. Ungues sicut in L. leonina, sed basi minus late dilatati. 



cJ . Pygidium margine apicali valde refiexo. Venter segmento 5° apice arcuatim emarginato, glabro, 6° magno, 



medio haud depresso, grosse setoso-punctato, longitudinaliter sulcato. 

 $ . Pygidium apice mediocriter refiexo. Venter segmento 5° parum arcuato-emarginato, 6° breviore, conveso, 

 grosse punctato. 



Long. 14-16 millim. 



Hab. Mexico, Parada, Oaxaca (Salle). 



Three examples. The great difference in the punctuation and pubescence of the 

 pygidium, in both sexes, indicates a species distinct from L. leonina, though the form 

 and sculpture of the head, thorax, and elytra are almost exactly similar. The sixth 

 ventral segment in the male shows no trace of the depressed median area, or wide
