I'd like to translate the label "Verify Captcha" that appears above the captcha

Hi!

I’d like to translate the label “Verify Captcha” that appears above the captcha. Here’s my page where the wo-reCAPTCHA is inserted: http://livrariadanubioeditora.com.br/cadastro/.

I’ve searched for “Verify Captcha” inside all the .php files of the plugin, but I couldn’t find this string.

Does anyone knows how to translate this?

Thanks in advance!
