178 LAMELLICOENIA. 



similarly dark-coloured and smooth, pruinose species of Lachnostema. The following 

 secondary sexual characters will facilitate its determination :— 



cJ . Pygidium mediocriter convexum, apice explanato-reflexo, nudum, rotundato-punctatum. Venter medio 

 mediocriter depressus, toto pruinosus, segmento 6° solum nitido, crebre punctato. Tibiarum posticarum 

 calcari inferiore connato, parvo, unciformi. "Ungues omnes (basi J § breviter dentati) apice profunde et 

 anguste fissi, dente inferiore paullo latiore. 



$ . Pygidium ante apicem convexum, subconicum, apice ipso explanato-reflexo. Venter convexus, pruinosus, 

 segmento 6° solum nitido, crebre punctato. Tibiarum posticarum calcaria sat brevia, compressa, libera. 

 Ungues omnes dente inferiore parum latiore, mediocriter remoto, deorsum curvato. 



9. Phy talus prolixus. 



Cylindricus, elytris prsecipue valde elongatis, supra glaber, nitidus, castaneo-fuscus vel castaneo-rufus, elytris 

 plerumque fulvo-testaceis ; clypeo brevi, transverso, medio profunde sinuato, lateribus rotundatis, sat 

 sparsim punctato ; tborace transverso, post medium haud angustato, angulis posticis rectis, sat dense 

 punctulato ; elytris undique punctatis, costis vix elevatis, interstitio suturali parce punctulato ; pectore 

 fulvo-birsuto. 

 c? . Pygidium parum convexum, glabrum, grosse disperse punctatum. Venter medio depressus, laevis, segmento 

 6° brevi, grosse punctato et setoso. Tibiarum posticarum calcar inferior breve connatum. Ungues apice 

 profunde fissi, dente inferiore paullo latiore et multo longiore. 

 5 . Pygidium a c? baud differt. Venter convexus, laevis, segmento 6° convexo, grosse punctato. Ungues 

 desunt. 



Long. 20-26 millim. 



Eab. Nicaragua, Chontales (Belt, Janson). 



Five examples, of which one only is of the female sex. 



The shape of the head is similar to that which prevails in the L. rorulenta and 

 L. fusca groups of Lachnostema, which also exhibit the peculiar feature of a soldered 

 lower spur to the hind tibiae of the male. 



10. Phytalus trichodes. 



P. pvMcolli similariter pubescens, sed major, clypeo medio sat acute sinuato, etc. Oblongus, fulvo-ochraceus, 

 subnitidus, undique sat breviter dense fulvo-pilosus et dense punctatus ; capite umbilicato-punctato ; 

 antennis rufis, nitidis, clava pallidiore, opaca ; pectore dense fulvo-villoso. 



Long. 17-20 millim. 



Hob. Mexico, Las Vigas (Hbge). 



Numerous examples were captured by Herr Hoge. P. trichodes is an oblong-ovate 

 species of tawny or reddish-ochreous colour, and densely clothed throughout with rather 

 short erect tawny hairs. The tarsal claws are dilated at the base, and, as in P. obsoletus, 

 differ as regards the apical fissure according to sex ; the following are the secondary 

 sexual characters : — 



cS . Pygidium sat elongatum, parum convexum, dense punctato-pilosum, margine apicali acuto, paullo reflexo. 

 Venter medio longitudinaliter depressus, subglaber ; segmentum 6 m magnum, convexum. Tibiarum posti- 

 carum calcari inferiore affixo brevi, unciformi. Ungues omnes apice anguste fissi, dente inferiore majore 

 et longiore. 



$ . Pygidium glabrum, sparse punctatum, declive et paullo ante apicem unituberculatum. Venter medio 

 convexus, laevis, suturis l a -4 m obliteratis, segmento 6° convexo. Tibiarum posticarum calcaria aequaliter 

 elongata, ensiformia. Ungues omnes apice profunde fissi, dente inferiore distanti deorsum curvato.
