6. Strigoderma sallaei. (Tab. XIV. fig. 9.) 



8. vestitce affinissima, differt solum thorace semper seneo vel cupreo conoolor et sicut pygidio et corpore subtus 



dense incumbenter cinereo-piloso. 

 Long. 7-8 millim. S $ . 



Hab. Mexico, Cuernavaca {Salle, Edge), Parada, Tepansacualco, Juquila, Capulalpam, 

 Yolotepec (Salle). 



When the pubescence of the thorax is abraded it is difficult to distinguish this species 

 from S. vestita. The sexual characters and sculpture are similar. The thorax in 

 S. sailed, however, is less elongated in both sexes, and the closely packed punctures 

 are less confluent and confused ; its colour also is always dark brassy-green or dull 

 cupreous — there is no example in the tolerably large series examined tawny-red in 

 front, which seems to be the most prevalent colour in S. vestita. A specimen from 

 Juquila is figured. 



7. Strigoderma longicollis. (Tab. XIV. fig. 10.) 



Depressa, thorace angusto et elongate, supra glabra, fulvo-castanea, nitida, vertice, thorace vitta vaga mediana, 

 scutello suturaque (interdum elytris totis) fusco-nigris ; capite dense ruguloso-punctato ; thorace ante 

 medium subito dilatato, antice longe et gradatim angustato, postice valde sinuato, basi lato angulisque 

 posticis exstantibus acutis, dorso utrinque insequali sulcis vagis et latis obliquis impresso ibique grosse 

 scabroso-punctato, medio dorso convexo, discrete punctato, basi valde flexuoso medio sublobato, carinaque 

 obtusa laterali prope marginem a basi usque ad dilatationem ducta ; elytris latis deplanatis utrinque post 

 seutellum concavis calloque humerali valde elevato, sicut in 8. vestita punctato-sulcatis, sulcis sex inter 

 suturam et callum humeralem. Subtus et propygidii apex dense incumbente cinereo-pilosa, pygidio 

 subglabro, aspere punctato, nitido. Mesosternum latum, subverticale, apice nullo modo porrectum. 



Metasternum d medio densissime erecte hirsutum. 



Long. 9 millim. 



Hab. Mexico, Orizaba (Salle). 

 Three examples. 



8. Strigoderma contracta. (Tab. XIV. fig. 11.) 



S. hngicolli affinis ; multo minor. Breviter ovata antice angustata, parum convexa, nigro-aenea, elytris nigris,

 quadrate, angulis rotundatis, margine sat alte reflexo; thorace angusto, ante medium dilatato, antice 

 longe et gradatim angustato, postice valde sinuato, angulis acutis, posticis exstantibus, supra toto basi 

 tumore flexuoso margine basali fere parallelo et per latera continuato, margine antico utrinque incrassato 

 discoque oblique impresso, toto disco disperse haud profunde punctato ; elytris utrinque post seutellum 

 concavis, profunde punctato-striatis, interstitiis l°-8 m convexis, 9° angusto depresso. Pygidium confluenter 

 haud dense strigulosum cum propygidio corporeque subtus cinereo-pubescens. Mesosternum subverticali 

 apice tumidum sed haud porrectum. 5 . Elytrorum margo ante medium perparum arcuatus et incrassatus. 



Long. 6-64 millim. 



Hab. Mexico, Tepansacualco (Salle) ; Guatemala, Zapote (Champion). 



Five examples. The single Guatemalan representative is a female, and differs from 

 the others in the flexuous wheal across the base of the thorax and other inequalities
